The way the paper lands perfectly on the seat at 7:58 was either unplanned or this was take 23. Either way, the fact that Ryan seemed not to notice was the best part.
I live in the town where Felix Wankel had his workshop and lived while engineering the rotary engine. My mother knew him. Had a small dog apparently. He also developed a boat which could dive under waves. That's why his workshop is a few feet away from lake constance. The facility is owned by Audi today.
@@MrMrMrMrMrT Hitler invaded poland in september kicking off ww2...and its a bike from Germany. Hes saying dont get carried away like him...and Wankel was a "Not-See"
He is very good indeed. However when he stops playing Jeremy Clarkson he would be even better. But that is not mandatory, I have no problem with 2 Clarksons on this planet)
Rumour has it that Mazda has never actually stopped developing their rotary in their secret labs deep down underground. As a former RX8 owner, I sold before seal failure, I love the rotary and would love to have another….
you are right they are going to put a rotary engine in the extended range electric car they have now it going to run a generator to recharge the battery .
There might be truth to that! I've heard rumours of Mazda developing Wankel generators for use as range extenders in hybrid cars. They work pretty well at steady rpm! ~RF9
My parents were a Hercules dealer in the late 70's. Couldn't sell any of the 3 bikes initially sold to them by the company. So, the oil injector model(yes there was one you didn't have to pre-mix for) went to a business partner/investor. The 2 pre-mixers, dad road raced. One was a sprint race bike, the other the endurance bike. Never won anything, but never finished last. He ran them until about 1983.
Thats super rireous.my dad raced also but more like late 70s into early 80s.true hardcore kinda shit right there.i mean they had metal everything.and 4 wheelers were still bein tried out with 3 wheels for whatever reason.stupid lookin but do i still wanna try it out ? Damn well know it
there was one of them rotting for at least a decade outside a house (in athens greece) that as kid I would pass by it every day on my way to school (in the 90's), I guess the engine was dead and nobody could fix it.
They say the last 200 (or so) produced right when 1975 became 1976 had oil injection. They are easy to spot as there is *a visible "tube" indicating the level of the oil tank* on the side panel directly beneath the *second 'E'* in HERCULES that's painted on the gas tank. th-cam.com/video/1bni-fir4A8/w-d-xo.html
In 1974 I was in the Army, station in What was West Germany, and I remember the Hercules rotary engine motorcycle. I was fascinated by it but I couldn’t figure out how it worked. It was a nice looking bike and I still remember this weird motorcycle like it was yesterday. Thanks for doing a show on it, it made me fill young again.
I saw my first 1 in Spain, was amazed by it, plus my uncle had an early 1900s converted barge with a single rotory engine, which my father had to fiddle with to get running

When the Suzuk RE5 was contemporary, the Australian Motorcycle racing rules counted the capacity as twice the single-rotor-face capacity, so for the RE5, it was rated as a 1,000 cc. Bit more reasonable than counting 3/3, or 1/3. RE5 was of limited practicality, but that didn't stop me from riding from Melbourne to Darwin and back again, one fine month, about 5,000 odd miles. I have one sitting in the shed, waiting for me to move into a residence with a garage (or should I say: into a garage with attached residence). Good vid, I enjoyed it.
Great. The RE5 wasn't bad ride at all (I was a mechanic for a Suzuki/Kawasaki shop in New York) but had some peculiarities that just wouldn't be overcome. The styling of the first incarnation was a bit off what was pleasing the market but on the road, it was pretty nice. There were some odd stories coming down the pike about servicing them, one: don't put one on a dyno or you'll stand the chance of melting the aluminum exhaust manifold attached to the engine. Synching the two carburetor throats was tricky but once dialed in, it didn't vary enough to cause trouble.
@@whalesong999 The RE5 seems really interesting, but if I'd walked into a Suzuki dealership to look at one, I think I'd have probably ridden out on a GT550. Even today I'd love to have a Suzuki triple. Park it right next to my Kawasaki triple.
@@JETZcorp So refined, the Suzuki triples. I liked them too. The 550 did have an issue for a time with the starter clutches engaging and disintegrating the starter motor during operation but the factory covered that well.

Desmo valves are pretty much the best in the business in my opinion, much less to go wrong. That sevice was hefty enough though, I think around $800. I ride it very hard though, it's seen it's fair share of abuse.

Back in the '70s I had an Artic Cat snowmobile with the same Sachs rotary engine, the engine size was called a 303 though. It was a good, torquey motor, and was able to power up hills that the more powerful 440s would spin their tracks on. I always wanted to try a Hercules with that motor. Reciprocating engines have had over 100 years of development by almost every car and motorcycle manufacturing company to get them to the high level of refinement they now enjoy. By comparison, the rotary has had only a handful of companies even get to the point of building development mules, and only one has made a serious production engine. I've always wondered where we would be if the rotary had been invented first. Imagine trying to convince a rotary engine manufacturer that they need to replace their engine with something that had 100 times more parts and vibrated like a paint shaker.
NSU made Wankel. Sachs Mazda Suzuki Many others . All came to the same end. Norton made them and it took them down the dead end to bankruptcy ( or they were dead anyway and clutched at this straw) AIE makes them today and is aiming at the Drone market .I have a sneaking suspicion that they have Norton roots. While an attractive idea it is inherently full of compromise to make the concept work.
in the automotive industry, Mazda used a rotary engine for it's RX-7 and I've heard they we're really nice cars. I think the oil and gas combination is always a pretty big turnoff, but I also think two stroke engines have charisma despite of it... You've got a good point with the historical development of both engines
@@Leotheleprachaun yeah, what I meant by mentioning the two-stroke engine was only using it as a comparison to a rotary which also burns oil inside the ignition chamber. But thanks! I really didn't know they used a two stroke earlier
Rolls Royce made the compression problems and also the efficiency problems go away by using a two stage rotary. It made enough compression to work as a Diesel generator. In essence a supercharger/turbocharger hybrid. with a big compression rotary and a small rotary that used the compressed air from the big one and spat the remains of its combustion back on to the big one too. They were geared together. That still doesn't solve the lubrication issue, but it does solve the problem of how to get it to bang hard enough.
Seems like it would be more efficient to just use a supercharger as a first stage compressor instead of two wankels in a row? I’m quite sure that a Wankel rotor is far from the the ideal compressor.
It's been such a long time since I've even thought about Hercules bikes. Thanks for taking me down a trip through memory lane. I was always fascinated by these after seeing one for a ridiculous price in a magazine.
Hercules bikes is so way back then. As a kid I had one similar to this, a KTM with a Sachs two-stroke. Basically the same thing as all the others, just not Hercules
Missing the most important feature of the Hercules. At the motorcycle shop I worked at, we had a couple of Hercules advertising posters that clearly showed that if you purchased a Hercules, topless Scandinavian models would happily jump on the back of the seat. I still have no idea why it failed. That should have been the biggest feature.
I owned a 1973 Hercules Wankel 2000 in the early 1980's. All spare parts came out of Quebec, Canada. You had to *WRITE A LETTER* with a list of parts (including part #) you wanted. They replied with prices for each item. You then responded with which parts you wanted to buy and included a check. You accepted it because it was the only way to get them!!! I can't count the number of times people asked me if it was a jet engine!
there was one of them rotting for at least a decade outside a house (in athens greece) that as kid I would pass by it every day on my way to school (in the 90's), I guess the engine was dead and nobody could fix it OR they couldn't get the parts... :-(

@@mark3427 I just this second realized why I've been so patient with my Amazon Prime shipments taking a week to arrive instead of a day or 2. It's because I was born in a time of, *"It'll arrive when it arrives. A tracking number? What's that?"*
Only to the generations who do not know much. That engine, with out a energy eating rotating counter balance, (which both type engines have used), shakes a lot. Back in the day, I rode my buddies 1972 Artic Cat Panther snowmobile with Wankel engine and no counter balance. It shook like a paint shaker at Home Depot. You, the next generation, would not know that. But he is wrong---and that can easily be called a masterpeice if you don't know the difference. What story will a person speak, if they don't know? Nothing you can prove wrong.
@@eugene7518 Well, I never fell into the trap of buying a cell phone, and still I did not ride my bikes last summer. If many people prefer texting instead of riding,---mankind is doomed.
all the good things you had to say about it are just 2 stroke things, but a normal 2 stroke lasts longer (and that says something) and provides way more torque, this wasn't Pandora's box, it was the bottom of the barrel
I only saw this machine once. It was extremely expensive, compared to similar bikes and I didn't have the money for it. I still remember the sales brochure with the very Teutonic models posing with the bike. It was a very handsome machine with extremely high build-quality standards. It's a shame it did not succeed but I remember it as one of the bikes "that got away."
I don't agree. Yes it was handsome but the really big Company Hercules went out of Business because it did not work and the development was so expensive. All Wankels, except Mazdas were shit, because the Odea of Wankel is shit.
Felix Wankel and Oskar Heil were two German engineers who had an outsized impact on my early life. I'm 47 and had a modified 2nd gen RX-7 (non-turbo) from about 1997 to 2001. And I inherited ESS AMT-1 speakers back in high school that blew me away ("sound as clear as light").
Ryan, Sachs produced a Wankle engined dirt bike with leading link front suspension in the early seventies. It was a strange beast. A family friend kept his in my father's shop. It was an interesting ride.
I bought a new CBR500R the other week. Yesterday, a driver ran into it when I was in a roundabout. Now it’s in the shop getting repaired. I’m binging all of your videos until it’s fixed. You’re a legend, thanks mate.
My old RX-7 used to run so smooth, the tach redline featured a loud warning buzzer to try and ensure you didn't spin the rotors right out the engine 'block'
I don't think that would actually happen, not at that lower rpm. One guy I was chatting with had 4x of those engines stacked (I believe with the stock turbos though), and he had it set for something like 12k rpm redline. Apparently stacking those is easy, but he didn't know for the RX-8 (which is what I have and would love a quad rotor, let alone a beast of an octa-rotor like he made). On mine you get this barely audible little "beep" I don't even hear 99% of the time because it's so soft compared to the engine screaming, but they have a rev limiter at 9.5k rpm anyways. It is incredibly smooth, I once drove like half an hour down the highway and didn't realize it was in 3rd gear instead of 6th (just purring away 7-8k rpm), oddly didn't seem to affect fuel economy...
@@jakegarrett8109 Mazda's first commercial for a rotary engined car had a song that went something like "A piston engine goes boing boing boing, but a Mazda goes hmmmmmm!" th-cam.com/video/oHzeGEHWMjo/w-d-xo.html
About 25 years ago when I was an auto tech we had a customer who had one of those 3rd generation RX-7s with the twin rotor turbo engine (twin turbos? I can't remember). That thing was amazingly smooth and fast. Driving it felt like the closest thing to riding a big-bore sport bike. Wouldn't want to own it and have to pay the repair bills though.
@@jfess1911 It should be more like "brap, brap, ptu-pOW!". I like how they brag about the quite noise, lol, though mine does have an exhaust mod probably a little louder than stock. I'd compare them more to a rolling gang or warzone on wheels with the occasional gunshot sounds after getting to 9.5k rpm and shifting with some nice flames coming out the tailpipes.

I own 4 sachs 303 wankel snowmobile engines, and honestly that was the perfect application for them. They aren't just air cooled, but are also cooled by the fuel mixture, which solves both the oiling and cooling problems which shortened the life of other rotary designs. One of mine has well over 4000 miles which is a lot for a 70s snowmobile, and it still starts and runs like new. In fact, very one I've found will run awesome after it gets fresh crank seals and a good week long ATF soak to break up carbon deposits. It was really the fuel crisis that killed them more than anything else. They suck down gas but make amazing and smooth power for their weight.
Wankel engines were not popular at all in snow machines, sold very poorly and were fairly quickly discontinued. Sachs abandoned all development Wankel engines in 1977 and sold most of the tooling and rights to Norton... who lost a fortune and went bankrupt.
Bull. Cat sold 10,000 Panther 303s in one year alone. They ran great when tuned right and we sold a boat load in the 1970s. Time moved on they got expensive and the Kawasaki twins took over for Cat.
Yep, it was mostly the fuel economy that killed them with the gas crisis. Phenomenal power density but poor fuel economy. I recently got my hands on a 75 cheetah 295 Wankel, it has a mikuni slide carb instead of the tillotson diaphragm, makes a night and day difference in the tuning. The tollotsons are temperamental on the roatries, but even swapping a 303 over to a mikuni slide carb makes the engine far more stable. @@glenmallory9982
Having owned an RX3 from new I had a completely satisfactory experience with the engine. Small, well laid out. Easy to work on. Smooth. Very powerful. Lacking in low end torque. Not efficient at low throttle settings but quite comparable with other powerful machines when the power was being used. It had antipollution equipment fitted before it was normal on other cars. The manual warned against rapid warm up. Be gentle and let it reach operating temperature before getting to gung ho. A good idea with any motor I might add. The engine was heavier than it looked so I did have troubles with getting bogged. Too much weight up front and not enough at the rear.
Engine weight was not the reason for the RX3s handling troubles, it was chassis design. The handling of the RX3 was so poor it made Mazda look back at chassis design and make it the core of every car they made after that.
@@lobsterbark Mazda has never been a high performance marque... it is still primarily a cheap entry-level car for young first time buyers. Mazda no longer has any factory motorsports programs.
@@sandervanderkammen9230 That has nothing to do with it's chassis design though. Every car they make, they actually put time and effort into making them good to drive and handle well. Most manufacturers do not give a shit, they have zero respect for their customers and think they are too stupid to notice when their car drives like shit. And they are hardly "entry level". Mazdas are noticeably more expensive and nicer than their competitors.
@@lobsterbark Yes, it does absolutely... as a rule, cheap cars have rudimentary chassis design. Mazda has always been a cheap entry-level car. Mazda's attempts to move into a up scale luxury cars have been complete and utter failures... Eunos, Amati and efini were all failures.
The Wankel and it's many derivatives fail vs the conventional piston engine because of its very inefficient combustion chamber. It's cursed with a large wetted area to volume ratio so the heat of combustion is soaked up by the sides of the chamber instead of doing work. The best shape for efficient combustion would be a sphere which, of course, has the most volume to surface area. Nobody has yet figured out how to couple mechanical energy out of a sphere so we are stuck with the second best shape: the cylinder. The Wankel has good mechanical efficiency (but so does a two-stroke piston engine). The Wankel excels at getting a lot of hp out of a small size but that trochoidal combustion chamber makes it uncompetitive with piston engines whenever fuel efficiency counts.

Dave Longmont CO
Talking of " getting a lot of hp out of a small size " I was reading that MAZDA wanted to use a small Wankel fro Hybrid cars. Because of the size/hp ratio the idea was to mount a small Wankle to produce the energy needed by the main elctrical powertrain (or maybe for the batteries, so if you have an engine which reload the battieries, it increases your driving range). Which makes sense IMHO. Yes.. fuel efficiency of the Wankle is poor BUT not so relevant because of its size and scope.. I don't know how is this idea going.
@@x_mau9355 a big advantage to using an engine as a generator is that it can have a very narrow powerband, so it can be tuned for great efficiency and power output. Traditional car/bike drivetrains are limited by the need to have a very wide powerband.
Wankels are still going strong! I own a selflaunching glider (ASH 31 Mi) The engine is manufactered by Austro. I think it is developed from the Norton wankel. It is light, no vibrations and quieter than a twostroke. It is fuelinjected and has 57 hp. It works very well in this application. It has a separate oiltank, and mixes itself, and can run on 95 leadless car petrol. I have so far had no troubles with it.
The Austro AE50R only exists for special circumstances where high power to weight is extremely critical and fuel consumption and emissions are relatively unimportant. Powered gliders are a classic example as are milatary drones. This engine's fuel economy is pretty horible and its emissions are even worse. Fortunately it's not an issue in a glider because they have such small engines and they run for relatively short periods of time compared to their overall flight times.
@@nessie42786 When I was in my early20s there was a commercial sort of Go Kart track, they had suspension, that used an air cooled rotary engine. I loved that place. It was all timed laps. They went under pretty quickly.
As a RX-7 "mechanic", I have PTSD to this day about the seals that ... don't. Not really. Unless spinning at a steady RPM... a single good RPM. I think Wankel's make for great generator engines ...
And when it only works with one good RPM, that is what you use. That is why Wankel's are used on generators and such that does not need a range of speeds. Other uses is being coupled with Continuously variable transmissions like in a snowmobile.
I had a buddy buy a dead RX-7 and we got it going with split fire plugs - the smoke was so blue and sweat smelling... I just patted him on the back and shook my head. 'let it go, buddy.' was my advice. he was like ' what does this mean? what does this mean?'
Wow! I saw one of these Hercules at the hot rod show in Daytona Beach Yesterday and it was in about the same shape as this one. I was a Suzuki factory service rep when the RE5 rotary was introduced and one of my duties was to fix problems the dealer couldn't fix. I think I worked on every RE5 that was sold in my territory. I was never so happy to see a model dropped from our product line.
Yeah, for a lot less money you could buy a very similar Suzuki but with a proven and reliable 3-cylinder 2-stroke 750 engine that would out run the RE-5 and use less fuel doing it and run forever. So why did anybody buy the RE-5? Just to be different? Did former RE-5 owners move on to Tempters?

I was lucky enough to begin my motorcycle mech apprenticeship not long after the RE5 had been shot in the skull. Amazingly the tech college i was sent to had one gifted to them, we ran it up on the colleges dyno one day and despite not really making any real horsepower it still managed to set fire to the ducting attached to the muffler.
Definitely a fun engine design. I think a lot of people are drawn to it simply because it is different and unique. I had a couple of first generation rx7s. Actually they were relatively reliable. Never had any significant problems with him and both of them went past 150,000 miles. I think the 13B with fuel injection was probably the sweet spot on the engine. Fuel injection made it run a lot better, but yet was still early enough that emissions regulations weren't causing problems. Not long after that I think it just became a lost cause. There was no way you were going to get that thing to pass stricter emissions regulations. Without significantly increasing the complexity which kind of defeats the purpose. At the same time reciprocating piston designs got better and better forced induction increase the power to displacement ratio. And it kind of became pointless. I do think there is a definite place for rotaries. People have mentioned possible generators for hybrids. They do work very well for stationary power and constant RPM.
i reackon the carbon footprint of these engines might have an angle (pardon the pun) due to far lower manufacturing costs and components? you could get around the emission issue by using castor bean oil (a couple of oil manufacturers make some good products) there is a big rotary pop culture here in Australasia.
As for use as generator in series hybrid cars, 2 stroke Free Piston Linear Generators are promising. They have a common problem with the wankle. Oil needs to be premixed. Toyota might even be trying to run this engine on hydrogen.
@@GbMuthu You can have an oil tank and do direct oil injection.. many 2 strokes and the previous Mazda rotary's worked this way.. you can have low oil warnings for refilling the tank. I think the Mazdas had a reservoir built into the engine.. so when you did an oil change.. and poured in the oil.. it first filled that section... Then overflowed into the crankcase... And had a warning light for low oil. Been a while since I worked on one..
@@kens97sto171 pre mix or direct fuel injection, oil was always left to burn with the fuel. Not sure about wankle but recon might have been the case too.

I rebuilt a Mazda RX 3 rotary once (in the 80's); never seen so many "rings" (the compression seals do the same thing but are not round) in my life. It was very fiddly but quite fast since the "segments" bolted together in a jiffy and the bloody thing went like a robbers dream but did not like corners or stopping much, and you needed an audible warning siren to go off to tell you when to change gears as it was impossible to "hear" any revvs and when you did there was a rubber screech on every gear - even top (!) - until (I couldnt see the speed as I was terrified to take my eyes off the road) the thing felt like it was disintegrating and I wondered where the parachute was...Later in life I was a MC Mech also and worked on the Suzuki and the Norton so I'm cursed too...
Another unusual use of the Wankel design I've heard about is in an explosive actuated seatbelt tensioner. In a crash a small charge goes off which spins a Wankel rotor that winds up the belt. I don't recall which make and model(s) used or may still use them. It would be interesting to see if one could be adapted to running on air or steam.
@@PedroPioLopes Mine still runs, it's light weight, easy maintenance, and so smooth I once ran it 7-8k rpm for over a half hour on the highway before I realized it was in the wrong gear (didn't seem to affect my fuel economy either).

@@PedroPioLopes Well yes, its a baby sub-250 pound engine that fits in an 18" cube that's NA. I think they should have came with turbos, otherwise its barely beating the GSX-R 1000cc bike I'm looking at in terms of power/size, also they set a very low rpm limit at 9.5k rpm stock instead of something more reasonable like 12k. Mine I've had to do very little maintenance, the most unreliable thing are the headlights... Why can't they make headlights last as long as the ones on my 30 year old Mercedes? Trying some LEDs now, otherwise headlights would die every 6 months (and I don't do much night driving). Second most unreliable thing are coil packs, you basically want to change those every time you change a sparkplug! Why do stores only carry 1x coil pack? I had to bike over to several stores just to replace 2 of them, you can't even get a matching set without ordering them (maybe the mixed brands is part of it having 4 different brands of coil packs, but I'm sure they are same assembly line). That's basically it, for maintenance I try to remember to change the oil relatively on time (also don't follow the suggested oil, use heavier), change the oil filter every other time, and I dump a random amount of 2 stroke oil in the tank when I'm filling up (a good portion always ends up on the side of my car, meh, whatever, clean it off when it gets on the brake disks). I also make sure to redline it every time I drive it, you do that and you're golden, drive it like you stole it (burns out the carbon from the cold side), its quite easy and make sure to thrash it and you won't have much issue!

Look up: Inventor: "Nikola Tesla", Name of Invention: "Bladeless Rotary Turbine Engine", approximate date of U.S. Patent: 1890. One moving part, ZERO vibration, can be made to run as an "Internal Combustion Engine", also works with high or low-pressure steam, compressed air, gases, etc. (It's roughly based on his patent of ~1870, a water pump.)
It produced incredible rpm but no real torque, the basis of molecular interaction with the surfaces of flat disks is not sticky enough even with steam. You can stack CD's and make one.
It works well as a pump for viscous liquids bit is not as efficent as a blade turbine. It also has trouble with steam as the discs warp due to the temperature gradient caused by the expanding steam. This gets worse the more you scale it up.
Clicked on the video out of curiosity, got interested when you mentioned wankel engine since I love Mazda's, then ended up staying and watching the whole video because of how good the story telling was. I have now liked and subbed!
Suzuki lost a lot of money on each RE5 they sold, but I once read that their development of apex seals ended up being what mazda needed to fix their own problems, so paid suzuki royalties for their designs for many years. So in the end it did work out for both companies. Rotaries were the engine of the future in the late 60's and into the early 70's until the problems with building and especially reliability were too big to deal with. Add to that poor economy and high emissions and everyone but Mazda gave up. Mazda may have yet another rotary powered car in the works, and anyone who drove their cars for a while will tell you the rotary is a real experience, and good one. They're actually a lot of fun and quite powerful, and easy to tune for more. I fell in love with the Rx8, almost bought one, but 16 MPG on premium was too high a price to deal with. The chassis and driveline of that car are amazing though.
@@todydn Mazda's rotaries had a pump that added engine oil to the intake the whole time. So yeah, adding oil was normal. Early ones had an interesting cold start system that pumped antifreeze into the intake as well. I never saw the couple people with old RX's use that though.
@@sandervanderkammen9230 Mazda is still around and often talks about a new generation rotary. I drove and almost bought an Rx8, the test drive was amazing, one of the best little cars I have driven, and i still love rotary engines. Everyone else that tried building rotaries eventually failed except mazda.
Hi Ryan! Your videos are the BEST thing on the internet. Everything about them is pure gold. I usually watch videos at 1.5X speed but I watch yours at regular speed to savor every second of them. Please never stop making them!!
Somewhat off topic but how you managed to squeeze this in between non-stop pissing rain is truly impressive. That scene at Cycle BC was hysterical... "Turn it off!" "What???" cough...cough...cough
The history and complexity you present on your channel is nothing short of amazing. Thanks for your constant digging and hard work to bring us all of these gems.
First time I've seen this engine and I spot the design flaw. They should have increased the grimbleflute a further 2 microsnards then aligned the fungle tweeter to the drooble oscillator. Then simply cruglulate the declination of the hingstal comparator.
The Wankel is an interesting engine, I used to have a 1984 Mazda RX-7. The engine was only good for about 100,000 miles, but that little engine could turn the RPM. I ran mine at around 10,000 RPM in 2nd gear for about a mile and backed off because I was running out of road, as I was delivering it to a dealership for trade.
Lol far from truth my 85 gsl has 200k+ and still going strong and that's out of the original 12a that unreliable rumor is bullshit, little more maintenance than a Honda civic but it's not a Ferrari . Absolutely love rotary engines, I own an 85 Gsl and the base model Gs, along with a second gen turbo ll, both the first gens ran well past a 100k, I only built the GS because I had some port work and clearancing done, to match my intake and exhaust work. Cheers to any fellow rotary enthusiasts
@@2strokejunkie686 Its not a rumor, it is a well-known and understood thar the Wankel engine is inherently unreliable and inferior to reciprocating engines it failed to replace. Mazda abandoned all development of Wankel engines in May 2009 after going bankrupt over the RX8 fiasco.
@@sandervanderkammen9230 was mainly because emissions and fuel economy, half of you who say this nonsense, have never even owned one, there is less to go wrong with far fewer moving parts, only weak points were the many seals the rotors require..my Rx7s have outlasted many of mine aswell as friends piston engines, even in high performance applications....only good for 100,000 my ass go sell that to someone else, cause I dont buy it. They only sold them since the 70s into the 2000s lol pretty damn successful, mazda capitalized on the design so to speak and is a big part other makes didn't go the rotary route. So much success they were even Deemed over efficient just like 2 strokes with unfair advantage in a racing sense, I agree much more suited for such use, but the whole unreliable rumor is absolutely bullshit.
@@2strokejunkie686 You sir are a big fat liar, the Mazda RX8 met or exceeded the strictest emissions regulations in the world right up until production ceased due to lack of sales.
LOL, pretty good. I attend the Vintage Festival at Barber Motorsport Park every year and there has been both Hercules and Suzuki Wankels displayed there. Ryan did a good job of explaining why the engine was a failure.
My first bike was a Hercules k125 BW V1 and it also ran on 1:25 Oil/Fuel. My mates asked if I could wait a little after the end of the school day before riding home because of the plumes of smoke that bike created and they didn't want to be behind me.
I rode the K125 while in the army as a dispatch rider. Smoked as hell and had a tendency to overheat and piston seizures, plus the front moved up on braking due to the weird fork construction.
I've just "discovered" your channel and I'm absolutely in love with it! even tough I am not a fan of motorcicles the aesthetics are just plainly perfect
Liquid Piston made rotary engine which looks line inside-out Wankel which apparently has much better fuel efficiency and power than Wankel engine. What is interesting is that Wankel himself also was considering shape Liquid Piston made, but wasn't able to seal it properly. Who knows, maybe if he would succeed all engines now would be Wankel engines.
Due to the fact the points of the 'triangle' are where the combustion chambers are, they can make that quite a bit more efficient. you still have apex seals too (twice as many of them in fact!) but they can be much bigger and chunkier because they're not moving. So it does have some promise. it's also freaking *tiny* for how much power it makes.
Liquid piston made the combustion chamber triangular and the rotor oval the inverse of traditional rotors which allows three combustions for every one revolution as opposed to one combustion per one revolution. This solved the efficiency part of the problem the fatal flaw with any rotary engine is the sheer amount of surface area that has to be sealed and lubricated at the same time.
Liquid piston's solution fixes some problems and aggravates others. E.g. they can get better combustion chamber geometry and maybe fewer issues with apex seals, but the flipside is that the porting situation is a bit bonkers (air and exhaust have to pass through the inside of the rotor) and the asymmetric heating problem that caused lots of issues in early rotaries is made even worse because the same side of the rotor faces every explosion... and unlike the housing of a normal wankel, you can't put a water jacket there to soak up the worst of the heat. It seems that their solution to this is to blow extra cooling air through the inside of the engine, which is probably needed for it to work at all, but air never cools as well as water.
@@DFX2KX The fact that the apex seals are stationary also means you can run regular gas and thus fuel injection, and have the oil sitting happily OUTSIDE the engine, not being spewed out the exhaust. Also, blowing extra cooling air + just running air to gas = this engine will turbocharge like a madman. Wankel's nail in the coffin was emission standards anyway. Two-strokes will suffer the same fate.
The way the paper lands perfectly on the seat at 7:58 was either unplanned or this was take 23. Either way, the fact that Ryan seemed not to notice was the best part.
Totally caught that. Had to be some sort of editing magic.

I live in the town where Felix Wankel had his workshop and lived while engineering the rotary engine. My mother knew him. Had a small dog apparently.

Rumour has it that Mazda has never actually stopped developing their rotary in their secret labs deep down underground. As a former RX8 owner, I sold before seal failure, I love the rotary and would love to have another….
They are awesome when they aren’t broken, lol.
Same! Bought my RX-8 at 12k miles and loved every day of it until 55k. It was a thrill to ride at 8k RPM.
you are right they are going to put a rotary engine in the extended range electric car they have now it going to run a generator to recharge the battery .
There might be truth to that! I've heard rumours of Mazda developing Wankel generators for use as range extenders in hybrid cars. They work pretty well at steady rpm! ~RF9

My parents were a Hercules dealer in the late 70's. Couldn't sell any of the 3 bikes initially sold to them by the company. So, the oil injector model(yes there was one you didn't have to pre-mix for) went to a business partner/investor. The 2 pre-mixers, dad road raced. One was a sprint race bike, the other the endurance bike. Never won anything, but never finished last. He ran them until about 1983.
Thats super rireous.my dad raced also but more like late 70s into early 80s.true hardcore kinda shit right there.i mean they had metal everything.and 4 wheelers were still bein tried out with 3 wheels for whatever reason.stupid lookin but do i still wanna try it out ? Damn well know it
there was one of them rotting for at least a decade outside a house (in athens greece) that as kid I would pass by it every day on my way to school (in the 90's), I guess the engine was dead and nobody could fix it.

When the Suzuk RE5 was contemporary, the Australian Motorcycle racing rules counted the capacity as twice the single-rotor-face capacity, so for the RE5, it was rated as a 1,000 cc. Bit more reasonable than counting 3/3, or 1/3.
RE5 was of limited practicality, but that didn't stop me from riding from Melbourne to Darwin and back again, one fine month, about 5,000 odd miles.
I have one sitting in the shed, waiting for me to move into a residence with a garage (or should I say: into a garage with attached residence).
Good vid, I enjoyed it.
Great. The RE5 wasn't bad ride at all (I was a mechanic for a Suzuki/Kawasaki shop in New York) but had some peculiarities that just wouldn't be overcome. The styling of the first incarnation was a bit off what was pleasing the market but on the road, it was pretty nice. There were some odd stories coming down the pike about servicing them, one: don't put one on a dyno or you'll stand the chance of melting the aluminum exhaust manifold attached to the engine. Synching the two carburetor throats was tricky but once dialed in, it didn't vary enough to cause trouble.
@@whalesong999 The RE5 seems really interesting, but if I'd walked into a Suzuki dealership to look at one, I think I'd have probably ridden out on a GT550. Even today I'd love to have a Suzuki triple. Park it right next to my Kawasaki triple.
If I rode from Melbourne to Darwin,, I would have definitely not gone back to Melbourne!!!
@@JETZcorp So refined, the Suzuki triples. I liked them too. The 550 did have an issue for a time with the starter clutches engaging and disintegrating the starter motor during operation but the factory covered that well.

Back in the '70s I had an Artic Cat snowmobile with the same Sachs rotary engine, the engine size was called a 303 though. It was a good, torquey motor, and was able to power up hills that the more powerful 440s would spin their tracks on. I always wanted to try a Hercules with that motor.
Reciprocating engines have had over 100 years of development by almost every car and motorcycle manufacturing company to get them to the high level of refinement they now enjoy. By comparison, the rotary has had only a handful of companies even get to the point of building development mules, and only one has made a serious production engine. I've always wondered where we would be if the rotary had been invented first. Imagine trying to convince a rotary engine manufacturer that they need to replace their engine with something that had 100 times more parts and vibrated like a paint shaker.
NSU made Wankel.

His jokes land so soft it takes you a second to comprehend
but he just said
Rolls Royce made the compression problems and also the efficiency problems go away by using a two stage rotary. It made enough compression to work as a Diesel generator. In essence a supercharger/turbocharger hybrid. with a big compression rotary and a small rotary that used the compressed air from the big one and spat the remains of its combustion back on to the big one too. They were geared together.
That still doesn't solve the lubrication issue, but it does solve the problem of how to get it to bang hard enough.
The issue comes when you bang too hard without lubrication, only bad things come from that ;)
@@sandwichmaker1289 When I bang with lubrication there is a change of pants that follows. ; )
AIE from UK has a Wankel engine with proper lubrication.
As said above swapping the Dorito and egg-shapes with a spark at each corner solves the poor blow down stroke and the excessive flame quenching.
Seems like it would be more efficient to just use a supercharger as a first stage compressor instead of two wankels in a row? I’m quite sure that a Wankel rotor is far from the the ideal compressor.
It's been such a long time since I've even thought about Hercules bikes.
Thanks for taking me down a trip through memory lane. I was always fascinated by these after seeing one for a ridiculous price in a magazine.

Ryan,
Sachs produced a Wankle engined dirt bike with leading link front suspension in the early seventies. It was a strange beast. A family friend kept his in my father's shop. It was an interesting ride.
Wild! Hercules also had an off-road variant with this engine - the 502GS. Super rare, I gather. ~RF9
I bought a new CBR500R the other week.
Yesterday, a driver ran into it when I was in a roundabout. Now it’s in the shop getting repaired.
I’m binging all of your videos until it’s fixed. You’re a legend, thanks mate.
Oh man, I hope your bike's fixed soon!
Nice bike, it's a shame. I had a '75 CB100 when I was a kid, but my ma made me get rid of it before someone ran into me.
My old RX-7 used to run so smooth, the tach redline featured a loud warning buzzer to try and ensure you didn't spin the rotors right out the engine 'block'
Yeah, and forget about hearing it idle at a traffic light.
I don't think that would actually happen, not at that lower rpm. One guy I was chatting with had 4x of those engines stacked (I believe with the stock turbos though), and he had it set for something like 12k rpm redline. Apparently stacking those is easy, but he didn't know for the RX-8 (which is what I have and would love a quad rotor, let alone a beast of an octa-rotor like he made). On mine you get this barely audible little "beep" I don't even hear 99% of the time because it's so soft compared to the engine screaming, but they have a rev limiter at 9.5k rpm anyways.
It is incredibly smooth, I once drove like half an hour down the highway and didn't realize it was in 3rd gear instead of 6th (just purring away 7-8k rpm), oddly didn't seem to affect fuel economy...
@@jakegarrett8109 Mazda's first commercial for a rotary engined car had a song that went something like "A piston engine goes boing boing boing, but a Mazda goes hmmmmmm!" th-cam.com/video/oHzeGEHWMjo/w-d-xo.html
About 25 years ago when I was an auto tech we had a customer who had one of those 3rd generation RX-7s with the twin rotor turbo engine (twin turbos? I can't remember). That thing was amazingly smooth and fast. Driving it felt like the closest thing to riding a big-bore sport bike. Wouldn't want to own it and have to pay the repair bills though.
@@jfess1911 It should be more like "brap, brap, ptu-pOW!". I like how they brag about the quite noise, lol, though mine does have an exhaust mod probably a little louder than stock. I'd compare them more to a rolling gang or warzone on wheels with the occasional gunshot sounds after getting to 9.5k rpm and shifting with some nice flames coming out the tailpipes.
That fart blast off on the rotary bike was awesome!! Lol

I used to ride its nemesis, the Suzuki RE5 Wankel in the late seventies. Enjoyed your presentation so much I'd forgotten how first class you are your craft. Informative and entertaining, most others on YT don't get anywhere close.
I own 4 sachs 303 wankel snowmobile engines, and honestly that was the perfect application for them. They aren't just air cooled, but are also cooled by the fuel mixture, which solves both the oiling and cooling problems which shortened the life of other rotary designs. One of mine has well over 4000 miles which is a lot for a 70s snowmobile, and it still starts and runs like new. In fact, very one I've found will run awesome after it gets fresh crank seals and a good week long ATF soak to break up carbon deposits. It was really the fuel crisis that killed them more than anything else. They suck down gas but make amazing and smooth power for their weight.
Wankel engines were not popular at all in snow machines, sold very poorly and were fairly quickly discontinued.
Sachs abandoned all development Wankel engines in 1977 and sold most of the tooling and rights to Norton... who lost a fortune and went bankrupt.
You don't mention that in 1989 the the Norton rotary had a good success on the tarmac in the British road racing Cup beating the factory Yamaha's
Bull. Cat sold 10,000 Panther 303s in one year alone. They ran great when tuned right and we sold a boat load in the 1970s. Time moved on they got expensive and the Kawasaki twins took over for Cat.
Yep, it was mostly the fuel economy that killed them with the gas crisis. Phenomenal power density but poor fuel economy. I recently got my hands on a 75 cheetah 295 Wankel, it has a mikuni slide carb instead of the tillotson diaphragm, makes a night and day difference in the tuning. The tollotsons are temperamental on the roatries, but even swapping a 303 over to a mikuni slide carb makes the engine far more stable. @@glenmallory9982
Having owned an RX3 from new I had a completely satisfactory experience with the engine. Small, well laid out. Easy to work on. Smooth. Very powerful.
Lacking in low end torque. Not efficient at low throttle settings but quite comparable with other powerful machines when the power was being used.
It had antipollution equipment fitted before it was normal on other cars. The manual warned against rapid warm up. Be gentle and let it reach operating temperature before getting to gung ho. A good idea with any motor I might add. The engine was heavier than it looked so I did have troubles with getting bogged. Too much weight up front and not enough at the rear.
Thank you for revealing that you know absolutely nothing about cars...
Engine weight was not the reason for the RX3s handling troubles, it was chassis design. The handling of the RX3 was so poor it made Mazda look back at chassis design and make it the core of every car they made after that.
@@lobsterbark Mazda has never been a high performance marque... it is still primarily a cheap entry-level car for young first time buyers.
Mazda no longer has any factory motorsports programs.
@@sandervanderkammen9230 That has nothing to do with it's chassis design though. Every car they make, they actually put time and effort into making them good to drive and handle well. Most manufacturers do not give a shit, they have zero respect for their customers and think they are too stupid to notice when their car drives like shit.
And they are hardly "entry level". Mazdas are noticeably more expensive and nicer than their competitors.
@@lobsterbark Yes, it does absolutely... as a rule, cheap cars have rudimentary chassis design.
Mazda has always been a cheap entry-level car.
Mazda's attempts to move into a up scale luxury cars have been complete and utter failures... Eunos, Amati and efini were all failures.
The title really resonates after the conclusion. Another piece of masterful storytelling. Thank you!
"I went to poland in september, it was lovely! You just can't get carried away"
Comedy genius right here.
The Wankel and it's many derivatives fail vs the conventional piston engine because of its very inefficient combustion chamber. It's cursed with a large wetted area to volume ratio so the heat of combustion is soaked up by the sides of the chamber instead of doing work. The best shape for efficient combustion would be a sphere which, of course, has the most volume to surface area. Nobody has yet figured out how to couple mechanical energy out of a sphere so we are stuck with the second best shape: the cylinder. The Wankel has good mechanical efficiency (but so does a two-stroke piston engine). The Wankel excels at getting a lot of hp out of a small size but that trochoidal combustion chamber makes it uncompetitive with piston engines whenever fuel efficiency counts.
we had an Re5 rotary ZOOK ! at our shop in Co Usa..10 years ago. Amazing. but i liked ( loved ) my dads Gt750 Buffalo MORE! I still flip my shitt when I seen one ( both)..Notice: The Herc W2000 has CO plates>? how am I NOT stalking this Bike ?? How did i not know it was HERE>? LOL RF9 might have it in BC Duhhh.
Dave Longmont CO
See the gas turbine helicopter engine. Most power to weight ratio
Try looking up liquid piston rotary engine
Talking of " getting a lot of hp out of a small size " I was reading that MAZDA wanted to use a small Wankel fro Hybrid cars.
Because of the size/hp ratio the idea was to mount a small Wankle to produce the energy needed by the main elctrical powertrain (or maybe for the batteries, so if you have an engine which reload the battieries, it increases your driving range).
Which makes sense IMHO.
Yes.. fuel efficiency of the Wankle is poor BUT not so relevant because of its size and scope..
I don't know how is this idea going.
@@x_mau9355 a big advantage to using an engine as a generator is that it can have a very narrow powerband, so it can be tuned for great efficiency and power output. Traditional car/bike drivetrains are limited by the need to have a very wide powerband.
Wankels are still going strong! I own a selflaunching glider (ASH 31 Mi) The engine is manufactered by Austro. I think it is developed from the Norton wankel.
It is light, no vibrations and quieter than a twostroke. It is fuelinjected and has 57 hp. It works very well in this application. It has a separate oiltank, and mixes itself, and can run on 95 leadless car petrol. I have so far had no troubles with it.
The Austro AE50R only exists for special circumstances where high power to weight is extremely critical and fuel consumption and emissions are relatively unimportant. Powered gliders are a classic example as are milatary drones. This engine's fuel economy is pretty horible and its emissions are even worse. Fortunately it's not an issue in a glider because they have such small engines and they run for relatively short periods of time compared to their overall flight times.
Can I put it on a go kart?
@@nessie42786 Sure, as long as you are happy to spend $20k+ on a go kart engine.
@@nessie42786 When I was in my early20s there was a commercial sort of Go Kart track, they had suspension, that used an air cooled rotary engine. I loved that place. It was all timed laps. They went under pretty quickly.
*Wankel engines are inherently unreliable and cannot meet the minimum PFTR reliability standards for passenger aircraft.*
As a RX-7 "mechanic", I have PTSD to this day about the seals that ... don't. Not really. Unless spinning at a steady RPM... a single good RPM. I think Wankel's make for great generator engines ...
And when it only works with one good RPM, that is what you use. That is why Wankel's are used on generators and such that does not need a range of speeds. Other uses is being coupled with Continuously variable transmissions like in a snowmobile.
I had a buddy buy a dead RX-7 and we got it going with split fire plugs - the smoke was so blue and sweat smelling... I just patted him on the back and shook my head. 'let it go, buddy.' was my advice. he was like ' what does this mean? what does this mean?'

A truly genius comedian, his videos are hilarious..
Wow! I saw one of these Hercules at the hot rod show in Daytona Beach Yesterday and it was in about the same shape as this one. I was a Suzuki factory service rep when the RE5 rotary was introduced and one of my duties was to fix problems the dealer couldn't fix. I think I worked on every RE5 that was sold in my territory. I was never so happy to see a model dropped from our product line.
God what a horrible task to be entrusted with. I'm glad you never lost your mechanical interest after that design quagmire.
Yeah, for a lot less money you could buy a very similar Suzuki but with a proven and reliable 3-cylinder 2-stroke 750 engine that would out run the RE-5 and use less fuel doing it and run forever. So why did anybody buy the RE-5? Just to be different? Did former RE-5 owners move on to Tempters?

I was lucky enough to begin my motorcycle mech apprenticeship not long after the RE5 had been shot in the skull. Amazingly the tech college i was sent to had one gifted to them, we ran it up on the colleges dyno one day and despite not really making any real horsepower it still managed to set fire to the ducting attached to the muffler.
@@barryervin8536 ohhh! I so remember that triple 2 stroke. That thing was scary fast…an absolute hoot to ride!
Definitely a fun engine design. I think a lot of people are drawn to it simply because it is different and unique.
I had a couple of first generation rx7s. Actually they were relatively reliable. Never had any significant problems with him and both of them went past 150,000 miles.
I think the 13B with fuel injection was probably the sweet spot on the engine. Fuel injection made it run a lot better, but yet was still early enough that emissions regulations weren't causing problems. Not long after that I think it just became a lost cause. There was no way you were going to get that thing to pass stricter emissions regulations. Without significantly increasing the complexity which kind of defeats the purpose.
At the same time reciprocating piston designs got better and better forced induction increase the power to displacement ratio. And it kind of became pointless.
I do think there is a definite place for rotaries. People have mentioned possible generators for hybrids. They do work very well for stationary power and constant RPM.
i reackon the carbon footprint of these engines might have an angle (pardon the pun) due to far lower manufacturing costs and components? you could get around the emission issue by using castor bean oil (a couple of oil manufacturers make some good products) there is a big rotary pop culture here in Australasia.
I feel like rotaries get a bad rap because people dont leave them stock....
As for use as generator in series hybrid cars, 2 stroke Free Piston Linear Generators are promising. They have a common problem with the wankle. Oil needs to be premixed. Toyota might even be trying to run this engine on hydrogen.
@@GbMuthu
You can have an oil tank and do direct oil injection.. many 2 strokes and the previous Mazda rotary's worked this way.. you can have low oil warnings for refilling the tank.
I think the Mazdas had a reservoir built into the engine.. so when you did an oil change.. and poured in the oil.. it first filled that section... Then overflowed into the crankcase... And had a warning light for low oil. Been a while since I worked on one..
@@kens97sto171 pre mix or direct fuel injection, oil was always left to burn with the fuel. Not sure about wankle but recon might have been the case too.

Get this book, it will change your life: Back Mechanic by Dr. Stuart McGill
I rebuilt a Mazda RX 3 rotary once (in the 80's); never seen so many "rings" (the compression seals do the same thing but are not round) in my life. It was very fiddly but quite fast since the "segments" bolted together in a jiffy and the bloody thing went like a robbers dream but did not like corners or stopping much, and you needed an audible warning siren to go off to tell you when to change gears as it was impossible to "hear" any revvs and when you did there was a rubber screech on every gear - even top (!) - until (I couldnt see the speed as I was terrified to take my eyes off the road) the thing felt like it was disintegrating and I wondered where the parachute was...Later in life I was a MC Mech also and worked on the Suzuki and the Norton so I'm cursed too...
Another unusual use of the Wankel design I've heard about is in an explosive actuated seatbelt tensioner. In a crash a small charge goes off which spins a Wankel rotor that winds up the belt. I don't recall which make and model(s) used or may still use them. It would be interesting to see if one could be adapted to running on air or steam.

@@jakegarrett8109 The RX-8 is extremely un-reliable and underpowered
@@PedroPioLopes Well yes, its a baby sub-250 pound engine that fits in an 18" cube that's NA. I think they should have came with turbos, otherwise its barely beating the GSX-R 1000cc bike I'm looking at in terms of power/size, also they set a very low rpm limit at 9.5k rpm stock instead of something more reasonable like 12k.
Mine I've had to do very little maintenance, the most unreliable thing are the headlights... Why can't they make headlights last as long as the ones on my 30 year old Mercedes? Trying some LEDs now, otherwise headlights would die every 6 months (and I don't do much night driving). Second most unreliable thing are coil packs, you basically want to change those every time you change a sparkplug! Why do stores only carry 1x coil pack? I had to bike over to several stores just to replace 2 of them, you can't even get a matching set without ordering them (maybe the mixed brands is part of it having 4 different brands of coil packs, but I'm sure they are same assembly line).
That's basically it, for maintenance I try to remember to change the oil relatively on time (also don't follow the suggested oil, use heavier), change the oil filter every other time, and I dump a random amount of 2 stroke oil in the tank when I'm filling up (a good portion always ends up on the side of my car, meh, whatever, clean it off when it gets on the brake disks). I also make sure to redline it every time I drive it, you do that and you're golden, drive it like you stole it (burns out the carbon from the cold side), its quite easy and make sure to thrash it and you won't have much issue!

Look up: Inventor: "Nikola Tesla", Name of Invention: "Bladeless Rotary Turbine Engine", approximate date of U.S. Patent: 1890.
One moving part, ZERO vibration, can be made to run as an "Internal Combustion Engine", also works with high or low-pressure steam, compressed air, gases, etc.
(It's roughly based on his patent of ~1870, a water pump.)
the tesla turbine?
It produced incredible rpm but no real torque, the basis of molecular interaction with the surfaces of flat disks is not sticky enough even with steam. You can stack CD's and make one.
Nikola Tesla - ABSOLUTE GENIUS!
It works well as a pump for viscous liquids bit is not as efficent as a blade turbine. It also has trouble with steam as the discs warp due to the temperature gradient caused by the expanding steam. This gets worse the more you scale it up.

Clicked on the video out of curiosity, got interested when you mentioned wankel engine since I love Mazda's, then ended up staying and watching the whole video because of how good the story telling was. I have now liked and subbed!
Suzuki lost a lot of money on each RE5 they sold, but I once read that their development of apex seals ended up being what mazda needed to fix their own problems, so paid suzuki royalties for their designs for many years. So in the end it did work out for both companies. Rotaries were the engine of the future in the late 60's and into the early 70's until the problems with building and especially reliability were too big to deal with. Add to that poor economy and high emissions and everyone but Mazda gave up. Mazda may have yet another rotary powered car in the works, and anyone who drove their cars for a while will tell you the rotary is a real experience, and good one. They're actually a lot of fun and quite powerful, and easy to tune for more. I fell in love with the Rx8, almost bought one, but 16 MPG on premium was too high a price to deal with. The chassis and driveline of that car are amazing though.
Got 20 plus mpg in mine for 225k, loved it but michigan winter rusted it away, way fun car.
The RX8 was a $3 billion dollar disaster that bankrupted Mazda and killed off the entire RX brand for good.
Not to mention every third tank you need to add oil even the best built rotories burn oil like a still chainsaw
@@todydn Mazda's rotaries had a pump that added engine oil to the intake the whole time. So yeah, adding oil was normal. Early ones had an interesting cold start system that pumped antifreeze into the intake as well. I never saw the couple people with old RX's use that though.

The Wankel is an interesting engine, I used to have a 1984 Mazda RX-7. The engine was only good for about 100,000 miles, but that little engine could turn the RPM. I ran mine at around 10,000 RPM in 2nd gear for about a mile and backed off because I was running out of road, as I was delivering it to a dealership for trade.
I have lifetime memories of the Mazda at leMans. Ear splitting scream at 2am. That engine was indestructible.

I rode the K125 while in the army as a dispatch rider. Smoked as hell and had a tendency to overheat and piston seizures, plus the front moved up on braking due to the weird fork construction.

It's a good day when F9 posts
Liquid Piston made rotary engine which looks line inside-out Wankel which apparently has much better fuel efficiency and power than Wankel engine. What is interesting is that Wankel himself also was considering shape Liquid Piston made, but wasn't able to seal it properly. Who knows, maybe if he would succeed all engines now would be Wankel engines.
Due to the fact the points of the 'triangle' are where the combustion chambers are, they can make that quite a bit more efficient. you still have apex seals too (twice as many of them in fact!) but they can be much bigger and chunkier because they're not moving. So it does have some promise. it's also freaking *tiny* for how much power it makes.
Liquid piston made the combustion chamber triangular and the rotor oval the inverse of traditional rotors which allows three combustions for every one revolution as opposed to one combustion per one revolution. This solved the efficiency part of the problem the fatal flaw with any rotary engine is the sheer amount of surface area that has to be sealed and lubricated at the same time.
Liquid piston's solution fixes some problems and aggravates others. E.g. they can get better combustion chamber geometry and maybe fewer issues with apex seals, but the flipside is that the porting situation is a bit bonkers (air and exhaust have to pass through the inside of the rotor) and the asymmetric heating problem that caused lots of issues in early rotaries is made even worse because the same side of the rotor faces every explosion... and unlike the housing of a normal wankel, you can't put a water jacket there to soak up the worst of the heat. It seems that their solution to this is to blow extra cooling air through the inside of the engine, which is probably needed for it to work at all, but air never cools as well as water.
@@DFX2KX The fact that the apex seals are stationary also means you can run regular gas and thus fuel injection, and have the oil sitting happily OUTSIDE the engine, not being spewed out the exhaust. Also, blowing extra cooling air + just running air to gas = this engine will turbocharge like a madman.
Wankel's nail in the coffin was emission standards anyway. Two-strokes will suffer the same fate.
