KLR-650 bike the marine corps uses will run on either jet fuel or diesel. That’s not bad. For a few gallons of diesel and a box of crayons you can keep the bike and the rider fueled up and ready to go.
The Enfield Taurus was popular in India's rural areas, where the customer's priorities are typically different. They're usually not looking for flash or speed, but reliability, low TCO, fuel efficiency, ruggedness, simplicity (easier repair etc.) and durability, and the Taurus offered all that in spades. I remember an auto magazine once jokingly saying that the Taurus would reliably give you 60 kmpl (kilometres per litre/ 226.8 mpg) no matter the load ("whether there was one person, two people or you were towing an ox with it" (or something like that)). Never rode it myself, but the petrol (gasoline) version of the Royal Enfield Bullet was a smooth, effortless cruiser.
I owned a 1957 Royal Enfield Bullet 350cc. Made in Redditch (UK), I had many different British Bikes. The Enfield was outstanding when compared to every other Brit Bike. Always regretted parting with it.
@@peterduxbury927 Enfield has come a loooong way since then - check out their newer bikes if you can. Btw Enfield riders are practically a cult in India and you occasionally still see well maintained examples from the 1950s-1970s. My grandfather owned one from the mid 60s. He was so excited to tell me about it in 2019 just before he passed away. Apparently while going downhill, he'd switch off the engine and stand up (to stretch his legs) and it would slowly go "dhuk... dhuk... dhuk...". There are also stories of seeing ghosts on the highway during night rides. Fun stuff :P
I spotted one in mint condition maybe 5 years ago in my village and I had no idea it was a Taurus(wasn't much into bikes back then) but knew it was the first ever diesel bike I saw. And man was it solidly built. I didn't get to ride it but I did however sit and turn the beast on... It sounded and vibrated crazy, it felt as if it was possessed by an untamed beast waiting to come out. Will never forget the impression that it gave me. That bike was also a reason why I started looking more into bikes and slowly falling in love with them.
i love how he stated several times how much simpler diesel is then explain several complications, but in short diesel is scalable up and gas down. That is why container ships run diesel but a lawnmower is gasoline. Also i ride my bike in quite cold weather and have to wait to build up heat to run properly, diesel is famous to have massive problems starting cold and take way too long to get to operating temperature. The biggest killer for diesel is short distance when you build up carbon deposits fast and dont bring it to temperature to burn it off.
same issue i’ve had working on marine diesels. You gotta run them long enough to prevent that buildup and put a load on them. Although if you run them and maintain them frequently they will keep running
There are actually many diesel lawn mowers (they call them lawn tractors though) but yeah the best way to run a diesel is to turn it on break off the key and leave it on. You will get little to no fuel in the oil and it will run for centuries lol.
“I love cars, but I really LOVE motorcycles” as well! I’d love to see more motorcycle content from Donut. I’m a little bit of a BMW Boxer fanboy. Naturally, anything that covers any mode from das bairische motoren werke is cool by me!
I remember going on a fairly long ride on royal Enfield diesel once. Didn't feel any potholes on Indian roads.. mostly because the thud from the engine was constantly re-aligning my bones and changing the pace of my heart every now and then. 😅
That vibration thing is actually crucial for the driver, if your hands (i.e.) are exposed to prolonged periods of a mild vibration, then your hands will end up shaking for some time after the vibration stopped. That can become a nerve injury, if the vibration is high and prolonged enough.
I’m surprised harley owners don’t diesel swap their bikes! They’re already: big heavy loud vibrating underpowered high torque low power… I’d imagine harley riders would happily coal roll people too!
Swapping a non-motorcycle designed engine into a motorcycle has a massive barrier due to motorcycle transmissions are normally integrated as part of the motorcycle engine block. Even if you had an off the shelf transmission the ratio's would need to be adjusted regardless if it was derived from automobile or motorcycle. Using an automobile transmission would have such short gear ratio's that it would spin the tires and / or wheelie at inconvenient times in particular in the midst of a curve. Using a motorcycle transmission the gear ratio's would be so long that the top speed would be horrendous as the max diesel RPM is half or even lower compared to typical motorbike engine. Either option would also have the problem of properly aligning the belt, chain, or driveshaft transferring power to the rear wheel. Necessitating a clean slate frame design hence the lack of swap kits.
@@Cerberus984 well if those are the issues, more gears could simply be used. I'm still very surprised at the market has not created some sort of gutless diesel motorcycle yet akin to Harley-Davidsons
@@tambosnipes1652 no, they're very powerful 'Harley' engines. Compared to sport bikes, the horse power they make vs the size of the engine isn't great. The torque numbers are nice but that's not the whole story of any race. My Indian FTR makes 120hp out of 1200cc's from the factory. Compare that to a sportster 1200 at what, 58hp? Also, you have to buy the screaming eagle stuff separately and then have it installed, not a cheap option. My 06 CBR1000 and 05 GSXR1000 were making upwards of 150hp from the factory. While the torque was much lower than the big Harley engines, the Harley would lead a race for maybe 60ft and then get blown away and this is mostly due to the weight of the Harley keeping the front end down. Now the 1000cc sport bikes all make around 200hp or more. I'm not trying to sound confrontational or anything, just comparing apples to oranges on the internet. en.wikipedia.org/wiki/List_of_fastest_production_motorcycles_by_acceleration
Two acquaintance of mine had "Royal Enfield Taurus" both were satisfied with it's performance. Both were city users not long distance user. The time period when this bike was launched there was huge price difference between Diesel and Petrol. May be they are not using this bike anymore because of lack of spare parts. It's engine looked like and sounded like regular small agriculture water pump's engine.
15:03 It depends which tanks - for instance, turboshaft engines of M1 Abrams can run on practically everything, from JP-8 aviation kerosene to even perfumes. For those who don't know, turboshaft engine is a modified version of a jet engine, but with enormous turbine. It's extremely fuel-hungry, but can run on practically any fuel and with practically any power output.
Jeremiah : Long stroke, high low end torque, low high end power, center of gravity and balance problems, vibrations etc... are bad for bikes. Harley Davidson : Yes!
Great video, thanks. Royal Enfield had a diesel approx 500cc, in the 1950s. My mate Garry had one, from what I understand, they were a special order. I don't know much about them at all. It fired once every lamp-post, and was a poor handling bike due to fly wheel inertia and slow to alter revs relative to throttle input. Up side was he could achieve an easy 400 to 450 kms in the back roads and hills and 500 kms on main roads, it would slowly wind up to 120kph and thump along merrily sounding like a hyperactive Lister water pump. It could also pull a bulldozer out of mud with its torque. Garry also had a 3 wheel English service bike with a diesel from the late 1940s, approx 500 made by a niche manufacturer
It had a cement mixer engine or so it said from what I remember of a magazine review of the bike. It did say with a considerable amount of imagination you could imagine you were on a standard British big single.
Modern turbodiesels can compete. Not to the end of the video yet but I hope he mentions the one the US military uses. Hayes M1030 if you want to search. It can burn anything and go anywhere. It would be a bit lighter if either of those requirements could be removed, but if you ask me it's still one of the best bikes ever made, all-around. Edit: as hoped, he did get to it. :D Amazing piece of machinery, the cost could come down if more were made. I know the top speed isn't impressive, but imagine doing even 65 on dirt and uphill, with a heavy pack slung to the back and burning a tank full of twice-filtered gutter oil. "We don't need another hero."
FYI, there are also two-stroke diesel engines. Don't know if they've ever been put in a motorcycle, but I think they're typical in modern train locomotives, which are hybrid diesel/electric.
Yes that made me laugh too as diesel is much more expensive then regular gasoline right now. Why do you think the truckers are crying. Thanks a lot Brandon!! Fjb!!
"They discontinued it in 2000, one year before I was born." Me: Wait, Jeremiah is only 20 years old?! That's crazy. He's got a couple of city miles on him.
Royal Enfield India made a diesel variant of their bikes, the Royal Enfield Bullet Diesel or Taurus, it had a 325cc single-cylinder engine. Launched in 1993, the 325cc Royal Enfield Taurus (Bullet Diesel) motorcycle was specifically made for the Indian market in order to curb the rising trend of fitting a custom diesel engine in the 350cc Bullet frame.
i've seen a diesel bike in britain, back in the nineties, build in the late fifties... it had one cylinder an incredibly long stroke, a heavy flywheel, was unbelievably loud and needed a five gear transmission to get going, pretty much like a two wheeled traktor... and it was pulling a tandem trailer with a car wreck on top, which was kind of impressive!
A lot of riders convert their to diesel and gets good MPG. They are nice and fuel efficient. No one would buy petrol bikes when gas prices keeps going up.
There have been Diesel rotaries, but the whole point of having a Diesel engine is reduced fuel consumption. Rotaries have lower thermal efficiency so they burn more fuel, and that means if you want a Diesel, it will undoubtedly be a reciprocating piston engine.
+1 for the great education. My favorite compression raising trick is pushing the piston's crown into the heads, though that can only raise the compression ratio so far. I wonder if a sideways OP 2 -cyl engine would be a nice balance, get nice high compression ratios, & be able to rev higher from the shorter strokes....
Let's see. Under powered, over weight, vibrates, is loud,...I'm surprised Harley-Davidson didn't make one. That pretty much describes all of their bikes. And a lot of Harley buyers make them louder and shake more
Yeah! Don’t just enjoy your bike! Throw shade at other riders for not liking the same thing you do! Insult them by insinuating that they’re stupid! Now you’ve turned simple enjoyment of your bike in to something much spicier by adding hate and disrespect! Genius. More power to you. And as an added plus? If you happened to be insecure and immature, telling people they’re stupid for not liking what you like might make you feel better about yourself! Dude, you got it all figured out over there.
@@FUNKOfilms Are you bashing people for modifying their vehicle? I'm sorry, am I in the right room? Could've sworn I was watching a Donut video where that's done 99% of the time....
I’d love to see something like an 800cc single cylinder diesel bike that gets a hundred miles a gallon and can cruise at 70mph. Acceleration be damned.
The British army was playing with 1200CC diesel motorbikes a good few years back. Horizontally opposed BUT with a single combustion chamber in the middle and it was 2 stroke. (look up a deltic engine to get a rough idea). Nearly 200 MPH cruising at 70MPH. Top speed something like 150ish?
many years ago, here in the UK, i read in Motorcycle news that someone was taking older Triumph Tiger modles and putting in the smart car diesel engine. i think that was an 800cc diesel engine. not sure if it took off but was an interesting read for those out there that are not interested in speed and love to cruise and enjoy the ride lol
As cars become more numb, autonomous and expensive, motorcycles are the last refuge of the auto enthusiast. Hope y’all do more on bikes in the future. Love this show 🍩
I still believe thoroughly that older cars will always be available to purchase, drive, and modify. We don’t HAVE to purchase newer electric autonomous vehicles.
@@videoviewer8818 I agree but they won’t be mainstream. Owning/driving an ICE car will be limited to enthusiasts and have a much much smaller market , which inherently will increase the barrier to entry w.r.t. cost. The same way that no one banned recreational horse riding or yachting after cars and airplanes went mainstream, doesn’t mean it’s accessible to the masses anymore.
In Germany, there is still a small Motorcycle manufacturer called "Sommer Motorräder" that produces diesel powered bikes that use the engine out of a vibrating plate. The frames are mostly from Royal Enfield, but he is also using selfmade frames.
I was an instructor for the Marine Corps for those HDT KLR's. They were definitely a different animal to ride. HDT also entered one into the Baja 500 or 1000. It didn't do half bad. You do have to ride it different than any other type of motorcycle.
Hi Friends I am Anji M Swami from India and in our place (southern part of India) Diesel motor cycles are common. We used to mount Grieves 325 CC single cylinder diesel engine in Royal Enfield motor cycles. The fuel efficiency is around 70-80 KM/Littre. Even I used on such machine for six months immediately after my college. First the technique was introduced in Gobichettipalayam a small town in Erode District of Tamil Nadu the Southern part of India.
@@alklazaris3741 suitable for small towns with not much traffic -- like I guess small towns in Erode District; would be very unfriendly to other citizens of used much in a large city
I'm sure you have a lot of interesting vehicles down there in southern India. I think Indian car culture is pretty unique, even though I'd never be able to drive there lol
Sommer motorrader have diesel bikes. Gas mileage on that thing is; - hey bud! check out fuel? -There is some liquid on the bottom the tank - we 'll fill it next week.
I know this video is 2 years old, and nobody cares, but Kawasaki made a diesel version of the klr 650 that was so awesome that the marine corps used it. You can find them used for sale.
Actually, a very talented mechanic in my hometown built a small number of diesel bikes based on the Suzuki LS650 Savage I think. He called them Diesel Wiesel (weasle in english). Looked crazy, sounded crazy and was pretty cool 😊
ALSO, klr 650 is a dope bike. so easy to work on, literally made to be worked on outside someplace. Only thing is, it don't go fast and in major traffic, acceleration is the thing that makes motorcycles be viable to me.
As he said during the video "if you watched(?)", diesel engine are loud and shaking so bad it makes the rider hand numb and the sound is just pain in your ear lol
@@manddaallaa Any engine will tire your ears after a couple of hours of riding. Plus the wind noise. That's the first thing I learned in my first travel: earplugs and windshield are mandatory.
Lol. I was on a 1000km ride with some mates and the Harley that was with us did indeed shake itself apart over that distance. We were constantly pulling over to bolt it back together.
@@iamthebroker what year was is? The newer ones with the M8 motor are pretty smooth. Even the twin cam although it did vibrate when stationary is smooth once running. Last time I heard that happening to a Harley it was a 1972 Shovel head made during the AMF days. And this was only because the owner wanted a classic but didn’t maintain the bike worth shit.
@@antoniocampos6627 couldn’t tell you what model. It was a bit of shitter and the gear select lever kept vibrating loose. In the end we had to wire it on. I suspect it was badly maintained by its owner. I had two previous Harley and never had that problem, still have one now.
i love how invested Jeremiah gets when talking about motorcycles. so much potential for crossovers, hi/low bikes? moneypit bike?? f2f can defenetly be another show. love ya duud
Jeremiah is like Hammond and May in TG and GT. They always been a bikers, but in my opinion Clarkson has stopped any ideas of including bikes in the shows with a few exceptions. I hope this is not the case here.
@@rockymcallister4258 when I was refueling planes, it was described to me as JetA1 was 93 gas, and diesel was 87. then kerosene and bunker oil was just the trash. lol
Saw a homemade Diesel bike....used a frame from early 80's Enduro, and a one lung 16Hp diesel, then he used a golf cart trans and some custom machining to make use of the chain.
Sounds like a perfect addition to Harleys, they are already too loud, than they add those stereos and they already slow down traffic enough.... how to make them more annoying? Throw rolling coal into the mix
I mean I don't see how "too loud" is much of an argument for this, from the factory they're pretty quiet but modifying them to make them "loud" just seems like every other car guy out there putting an exhaust system on
Seems to me that the BMW R18 would be a near perfect platform to convert to diesel as most of those negatives already apply to the bike to start with. The engine is a 1802cc boxer twin the makes peak HP at 4750 RPM, which is pretty much diesel terrority anyway. Since it's a boxer it's already given up lean angle in tight turns so if you need to add more stroke it probably wouldn't be noticed if you loose another degree or two of lean angle. Not to mention that being a boxer means the center of gravity is very low too. The engine is already a heavy boy and the bike is a cruiser so a few extra pounds won't hurt it. Other than emissions I'm not seeing many downsides here lol
@@MolanLabe78 The Daihatsu three-cylinder diesel engine of 1000cc can fit the R-series gearbox (with a bit of lathe work and a conversion plate). 40bhp N/A and 60bhp turboed. The rev range is very similar to the boxer engine. I thought of this in 1990, but was told it wouldn't work. Imagine my surprise when I discovered that some German diesel bike freaks had done this conversion plenty of times in the years since I thought of it. Only goes to show there's always punters out there thinking of stuf to do with other stuff.
Just replace the sparkplugs with glow plugs fill the tank with diesel and it might just work anyway. (I'm only joking) maybe just an increase in the compression and a high pressure diesel pump. Chevy made a diesel from a petrol V8
@@itachi6352 Not sure that would work actually - alcohol (ethanol) is harder to ignite, thus might not fire. Ethanol has a pretty high octane, meaning it won't auto-ignite. This is advantageous in a spark-ignition engine, hence why a lot of tuner or souped up cars run E85, it's the highest octane stuff you can buy at a gas station (well used to be able to, haven't seen it lately) and is cheap compared to special race fuel. Diesels run by auto-ignition, the exact thing high octane is to prevent.
Dunno about that motor bit I know folks running used veggie oil in their turbo diesel trucks, claims of better mileage result but also warnings about seemingly premature injector failure and pitting.
Also riding gains more relationships too. I find the bike community is vary tight nit, I mean the biker wave exits, would you image waving at every car that passes lol
Very surprising, his knowledge and appearance is like that of an uncle to me and I am just 22. Just wow. I usually take things like that as a joke but seeing how the younger generation looks much mature than we did back then, and considering the way they dress, I mean it's not that hard to believe these days...
For many years I worked for a company that created mods for 4 stroke singles. Back when the US Military was trying to reach the "One Fuel" goal of all NATO countries (everything on the ground would run on diesel), we worked on a custom crankshaft and rod assembly for a company with the military contract to create a diesel engine for the KLR. The plan was to utilize as many of the KLR components as possible to keep cost low and parts sourcing easy. We tried many different designs for the rod assembly, main bearing, and piston, but even after finding solutions to most issues an Achilles heel remained; galling of the small end of the rod, meaning a radically different oiling system would be required. The company went back to the drawing board and basically built a completely new engine, using only the KLR gearbox and a few other stock components. I never got to see the innards of the end result, but did see plans and exploded diagrams, it's an amazing design. And no, I'm not going to say which company we were working with, there were many given the same contract with Hayes coming out as the winner.
Typically JP-8 with US tanks. That's supposed to be the standard for US military equipment in field and combat operations. If every engine is tuned to use the same fuel, it's just smoother from a logistics standpoint.
I didn't see anyone mention anything about the fact that you guys accidentally put fuel efficiency where torque shouldve been on the slide comparing the Royal Enfield Taurus to the Royal Enfield Bullet. Love you guys and I love coming back to watch these older videos. More bike content, please!
The Taurus can do something else. You can actually use the engine to work water pumps. Or anything else you want, the engine has more than one usable force absorbtion point. Quite useful in rural India back in the days. Today, I still ride my Diesel powered Enfield, just because I didn't find any better way to turn fuel into noise and vibrations without accidently producing power :)
DAMN I wish someone would build a Diesel cruiser. Something like a Goldwing for those coast to coast trips would be awesome on diesel efficiency. Cruisers don't need to feel like sport bikes. Some of them are 800Lb's anyway
Absolutely. All the "cons" of a diesel bike are negligible in a cruiser. The only real downside why we don't have them is emission restrictions. There's not a big enough market for diesel cruisers to justify the inversion in developing a cleaner bike, plus there's no much room for all the systems required for it like in a truck or a car.
Possible solutions: - Swirl injectors - Advanced composite materials, such as metal-reinforced ceramics. - Oval pistons - Spark-controlled compression ignition - Cylinder walls that are lined with an extremely thermally conductive material to make the temperature distribution as even as possible
That won't happen anytime soon and will be costly, so until then, petrol will be the better option. At that perspective though, I wonder how well will a electric powered bike performed.
You can do fuel injection with gasoline engines, too. There are upsides to the normal carburettor … especially when you do not keep the engine straight and level - think Spitfire. They had a fun time with negative g’s when the 109 did them - the 109 had fuel injection and the Spitfire a carburettor system that would stop delivering any fuel to the engine while in negative g’s - but would successfully overfill the carburettor and thus cause more problems once more normal situations reappeared. That meant the momentary loss of power while following through the manoeuvre and thus losing speed … Also you can run a high-power large-volume engine cooler and leaner by having a cross draft with both valves open for a long time - there is no fuel lost here - removing more used air and burn waste products and remove heat from the engine without using evaporative cooling of a rich fuel mix. This helps fuel economy. As I understand it, you’d still use a spark plug, though, you are just mixing fuel and air in the cylinder, not in the carburettor.
No doubt about it. 💚👍🏼 But, what if this crazy idea happens: An electric car that powers itself by using the rear wheels to supply DC current to the front wheels and charges its battery while it's running. 🤔
@@nuclearwinter21 with the energy conversion still being lost to heat you'll probably extend the range but may kill the battery with excessive heat from charging and may need a cooling system to save the generator system from heating as well
Interesting. This makes me think of Mazda's SkyActive-X. That's a gas engine, but has many similarities to diesel engines (it can do compression ignition and has high compression ratio). It seems some of the diesel engine disadvantages apply to that engine too. Mazda plans to continue to develop it and has said it will try to make an engine that can run on both gas and diesel. Mazda has told about the advantages of their engine, perhaps it is worthwile to make a video about the downsides of the SpCCi engine.
I remember for a certain period that engine had some serious reliability issues. I heard stories of engine replacements before 50k miles and it was happening to any model car with the engine. Obviously it’s been addressed since then but the tech is clearly very experimental. I personally don’t think it will be much more beneficial to standard Gas combustion no matter what they do with it. Especially when compared to EVs and their benefits over gas.
You cant really overcome the stroke problem. Like he said, Diesel engines need larger stroke and its hard getting all that material to rev high. Id say for a modern motorcycle you need at least 9 thousand RPM and i dont think a diesel engine will ever do that
If you put a nice big v-twin diesel in a cruiser, high RPM isn’t required, and nor is light weight. A big heavy thumping torquey v-twin diesel cruiser motorcycle would sell really well if the exhaust system sounds good, especially in America!
@@gabrielibarra5551 Achates may have a solution to that with an opposed piston 2-stroke, they've used fluid dynamic computer modeling to make it more efficient and lower emmissions than 4 strokes. 3 cylinders, 6 pistons, 2 crankshafts.
@@phillip_mcguinness7025 That’s going to ruin the simplicity that was a upside to diesel. And the weight would be insane. And Im assuming something that complicated wouldnt even be able to rev that high anyways

We have the technology to put a diesel in a motorcycle now I think the reason diesel didnt catch up is that all these emission devices you need to install for the motorcycle Imagine a DPF and another separate tank for ad blue
As long as it doesn’t reach 25hp it doesn’t need any emission stuff on it, I ride a crf250l with 17hp so honestly I think with today’s technology diesel is a very viable option for a fuel efficient bike
So what, he is 19 to 20 years old? He looks 34 tbh. How could he have spent "way too much time and money on bikes losing friends and girlfriends if he is barely old to drive. It's gotta be a joke
As a longtime rider familiar with how gasoline and Diesel engines work, it’s never occurred to me that putting a diesel in a motorcycle would be a good idea, for all the reasons you covered plus one you didn’t: heat. I think having a diesel between my legs would be like sitting above a cast iron stove. You brought up an amusing question so I watched for fun, and I think you did a fantastic job explaining all the issues clearly and concisely.

That vibration thing is actually crucial for the driver, if your hands (i.e.) are exposed to prolonged periods of a mild vibration, then your hands will end up shaking for some time after the vibration stopped. That can become a nerve injury, if the vibration is high and prolonged enough.

Swapping a non-motorcycle designed engine into a motorcycle has a massive barrier due to motorcycle transmissions are normally integrated as part of the motorcycle engine block. Even if you had an off the shelf transmission the ratio's would need to be adjusted regardless if it was derived from automobile or motorcycle.
Using an automobile transmission would have such short gear ratio's that it would spin the tires and / or wheelie at inconvenient times in particular in the midst of a curve. Using a motorcycle transmission the gear ratio's would be so long that the top speed would be horrendous as the max diesel RPM is half or even lower compared to typical motorbike engine. Either option would also have the problem of properly aligning the belt, chain, or driveshaft transferring power to the rear wheel. Necessitating a clean slate frame design hence the lack of swap kits.
@@Cerberus984 well if those are the issues, more gears could simply be used. I'm still very surprised at the market has not created some sort of gutless diesel motorcycle yet akin to Harley-Davidsons
Hatley davidson engines are very powerful espescially the screaming eagle ones
@@tambosnipes1652 no, they're very powerful 'Harley' engines. Compared to sport bikes, the horse power they make vs the size of the engine isn't great. The torque numbers are nice but that's not the whole story of any race. My Indian FTR makes 120hp out of 1200cc's from the factory. Compare that to a sportster 1200 at what, 58hp? Also, you have to buy the screaming eagle stuff separately and then have it installed, not a cheap option. My 06 CBR1000 and 05 GSXR1000 were making upwards of 150hp from the factory. While the torque was much lower than the big Harley engines, the Harley would lead a race for maybe 60ft and then get blown away and this is mostly due to the weight of the Harley keeping the front end down. Now the 1000cc sport bikes all make around 200hp or more.

It depends which tanks - for instance, turboshaft engines of M1 Abrams can run on practically everything, from JP-8 aviation kerosene to even perfumes.
For those who don't know, turboshaft engine is a modified version of a jet engine, but with enormous turbine. It's extremely fuel-hungry, but can run on practically any fuel and with practically any power output.

Great video, thanks.
Royal Enfield had a diesel approx 500cc, in the 1950s. My mate Garry had one, from what I understand, they were a special order. I don't know much about them at all. It fired once every lamp-post, and was a poor handling bike due to fly wheel inertia and slow to alter revs relative to throttle input. Up side was he could achieve an easy 400 to 450 kms in the back roads and hills and 500 kms on main roads, it would slowly wind up to 120kph and thump along merrily sounding like a hyperactive Lister water pump. It could also pull a bulldozer out of mud with its torque. Garry also had a 3 wheel English service bike with a diesel from the late 1940s, approx 500 made by a niche manufacturer
It had a cement mixer engine or so it said from what I remember of a magazine review of the bike. It did say with a considerable amount of imagination you could imagine you were on a standard British big single.
Think the diesel Royal Enfield sold well in India, & from what i heard was also made for a while in India?
Modern turbodiesels can compete. Not to the end of the video yet but I hope he mentions the one the US military uses. Hayes M1030 if you want to search. It can burn anything and go anywhere. It would be a bit lighter if either of those requirements could be removed, but if you ask me it's still one of the best bikes ever made, all-around.
Edit: as hoped, he did get to it. :D
Amazing piece of machinery, the cost could come down if more were made. I know the top speed isn't impressive, but imagine doing even 65 on dirt and uphill, with a heavy pack slung to the back and burning a tank full of twice-filtered gutter oil. "We don't need another hero."
Yube bobers that make these stupid vids should be running the country

A lot of riders convert their to diesel and gets good MPG. They are nice and fuel efficient. No one would buy petrol bikes when gas prices keeps going up.
great way of explaining things and really good animations!!!
This reminds me of the Rotary Diesel history, would be cool to have an episode on that
There have been Diesel rotaries, but the whole point of having a Diesel engine is reduced fuel consumption. Rotaries have lower thermal efficiency so they burn more fuel, and that means if you want a Diesel, it will undoubtedly be a reciprocating piston engine.
It's still an interesting concept. I like strange stuff like that

+1 for the great education.
My favorite compression raising trick is pushing the piston's crown into the heads, though that can only raise the compression ratio so far.

Seems to me that the BMW R18 would be a near perfect platform to convert to diesel as most of those negatives already apply to the bike to start with. The engine is a 1802cc boxer twin the makes peak HP at 4750 RPM, which is pretty much diesel terrority anyway. Since it's a boxer it's already given up lean angle in tight turns so if you need to add more stroke it probably wouldn't be noticed if you loose another degree or two of lean angle. Not to mention that being a boxer means the center of gravity is very low too. The engine is already a heavy boy and the bike is a cruiser so a few extra pounds won't hurt it. Other than emissions I'm not seeing many downsides here lol
First thing i thought of too. What about an R bike style?👍
@@MolanLabe78 The Daihatsu three-cylinder diesel engine of 1000cc can fit the R-series gearbox (with a bit of lathe work and a conversion plate). 40bhp N/A and 60bhp turboed. The rev range is very similar to the boxer engine.
I thought of this in 1990, but was told it wouldn't work.
Imagine my surprise when I discovered that some German diesel bike freaks had done this conversion plenty of times in the years since I thought of it.
Only goes to show there's always punters out there thinking of stuf to do with other stuff.
Just replace the sparkplugs with glow plugs fill the tank with diesel and it might just work anyway. (I'm only joking) maybe just an increase in the compression and a high pressure diesel pump. Chevy made a diesel from a petrol V8

For many years I worked for a company that created mods for 4 stroke singles. Back when the US Military was trying to reach the "One Fuel" goal of all NATO countries (everything on the ground would run on diesel), we worked on a custom crankshaft and rod assembly for a company with the military contract to create a diesel engine for the KLR. The plan was to utilize as many of the KLR components as possible to keep cost low and parts sourcing easy.
We tried many different designs for the rod assembly, main bearing, and piston, but even after finding solutions to most issues an Achilles heel remained; galling of the small end of the rod, meaning a radically different oiling system would be required. The company went back to the drawing board and basically built a completely new engine, using only the KLR gearbox and a few other stock components.
I never got to see the innards of the end result, but did see plans and exploded diagrams, it's an amazing design. And no, I'm not going to say which company we were working with, there were many given the same contract with Hayes coming out as the winner.
Here in Scotland, we made a diesel motorcycle for a while which was also 2wd, aimed at forestry and farming but also road legal.
That sounds really cool
What was it called?

"And whatever it is they put inside of tanks"
Gas, diesel, and jet fuel, believe it or not.
Typically JP-8 with US tanks. That's supposed to be the standard for US military equipment in field and combat operations. If every engine is tuned to use the same fuel, it's just smoother from a logistics standpoint.
Just trying to get views my guy?
The USMC converted a few KLR’s to run on JP5. I think they could run diesel too
I didn't see anyone mention anything about the fact that you guys accidentally put fuel efficiency where torque shouldve been on the slide comparing the Royal Enfield Taurus to the Royal Enfield Bullet. Love you guys and I love coming back to watch these older videos. More bike content, please!
"Costing less to run in most countries"
*angry UK noises*
He says "most" because it's not true in his home country either. Pretty much the same noises in the US but you guys add extra letters to some of them.
@@s.willis8426 It was more that it reminded me how much taxation we have in this country.....

Thankfully the 3p a liter is offset by mpg.

"When your engine is small it's all about that peak power".... that's what she said ;)

Vibrations
Diesel *****&
@@Gl-my8fw as all KLRs are lol. Making one that can run on basically anything just made sense
Ah yes desile
The Taurus can do something else. You can actually use the engine to work water pumps. Or anything else you want, the engine has more than one usable force absorbtion point. Quite useful in rural India back in the days. Today, I still ride my Diesel powered Enfield, just because I didn't find any better way to turn fuel into noise and vibrations without accidently producing power :)
Bro anyone else shocked Jeremiah was born in 2001?! Thought he was definitely older than that
Right? I WILL NOT believe he's only as old as I am :/
You all make me feel so old 😂🤣😂
I always thought that he was born in maybe 95-98 but 2001 is very young lol.
You tell me that he is still a teenager?
@@hazgebu so wild
@@hazgebu He's gotta be older than that. It's speculated he's nearly the same age as his partner, so somewhere around 40-ish
Harleys: how bout having all the downsides without the benefits!
DAMN I wish someone would build a Diesel cruiser. Something like a Goldwing for those coast to coast trips would be awesome on diesel efficiency. Cruisers don't need to feel like sport bikes. Some of them are 800Lb's anyway
We are working on it no
@axiomdiesel
BMW made one over 10 years ago and it was a cruiser that would pull the front tire in any gear because of double the torque
Absolutely. All the "cons" of a diesel bike are negligible in a cruiser. The only real downside why we don't have them is emission restrictions. There's not a big enough market for diesel cruisers to justify the inversion in developing a cleaner bike, plus there's no much room for all the systems required for it like in a truck or a car.
what the heck is Lb's anyway?
FINALLY A MOTORCYCLE EPISODE!!!

Possible solutions:
- Swirl injectors
- Advanced composite materials, such as metal-reinforced ceramics.
- Oval pistons
- Spark-controlled compression ignition
- Cylinder walls that are lined with an extremely thermally conductive material to make the temperature distribution as even as possible
That won't happen anytime soon and will be costly, so until then, petrol will be the better option. At that perspective though, I wonder how well will a electric powered bike performed.
You can do fuel injection with gasoline engines, too. There are upsides to the normal carburettor … especially when you do not keep the engine straight and level - think Spitfire. They had a fun time with negative g’s when the 109 did them - the 109 had fuel injection and the Spitfire a carburettor system that would stop delivering any fuel to the engine while in negative g’s - but would successfully overfill the carburettor and thus cause more problems once more normal situations reappeared. That meant the momentary loss of power while following through the manoeuvre and thus losing speed …
Also you can run a high-power large-volume engine cooler and leaner by having a cross draft with both valves open for a long time - there is no fuel lost here - removing more used air and burn waste products and remove heat from the engine without using evaporative cooling of a rich fuel mix. This helps fuel economy.
As I understand it, you’d still use a spark plug, though, you are just mixing fuel and air in the cylinder, not in the carburettor.
Basically buying an e bike and a diesel gen would be the way to go.
No doubt about it. 💚👍🏼
But, what if this crazy idea happens:
An electric car that powers itself by using the rear wheels to supply DC current to the front wheels and charges its battery while it's running. 🤔
Sure seems like a diesel-electric would be rad!
Never catch on though… no revs
@@KesslerMickschGeorgeII That's OK. It'll save you money for fuel and your land travels, though.
@@nuclearwinter21 with the energy conversion still being lost to heat you'll probably extend the range but may kill the battery with excessive heat from charging and may need a cooling system to save the generator system from heating as well
Interesting. This makes me think of Mazda's SkyActive-X. That's a gas engine, but has many similarities to diesel engines (it can do compression ignition and has high compression ratio). It seems some of the diesel engine disadvantages apply to that engine too. Mazda plans to continue to develop it and has said it will try to make an engine that can run on both gas and diesel. Mazda has told about the advantages of their engine, perhaps it is worthwile to make a video about the downsides of the SpCCi engine.
Learn about different types of combustion cycles
I remember for a certain period that engine had some serious reliability issues. I heard stories of engine replacements before 50k miles and it was happening to any model car with the engine. Obviously it’s been addressed since then but the tech is clearly very experimental. I personally don’t think it will be much more beneficial to standard Gas combustion no matter what they do with it. Especially when compared to EVs and their benefits over gas.
And that's what's gonna make it unreliable and expensive to maintain it
Honestly all the diesel problems sound way too fixable to let go of all the benefits.
I know right? I’d love a big bike that gets more than 40mpg.
You cant really overcome the stroke problem. Like he said, Diesel engines need larger stroke and its hard getting all that material to rev high.
Id say for a modern motorcycle you need at least 9 thousand RPM and i dont think a diesel engine will ever do that
If you put a nice big v-twin diesel in a cruiser, high RPM isn’t required, and nor is light weight. A big heavy thumping torquey v-twin diesel cruiser motorcycle would sell really well if the exhaust system sounds good, especially in America!
@@gabrielibarra5551 Achates may have a solution to that with an opposed piston 2-stroke, they've used fluid dynamic computer modeling to make it more efficient and lower emmissions than 4 strokes. 3 cylinders, 6 pistons, 2 crankshafts.
@@phillip_mcguinness7025 That’s going to ruin the simplicity that was a upside to diesel. And the weight would be insane. And Im assuming something that complicated wouldnt even be able to rev that high anyways
Underrated thing about this video is how deep into the math it gets and correctly adding that to the equation.
Imagine diesel Harley. You'd be even slower than before, you'd probably need to get speed for 10 miles just to pass truck
still faster than ferrari SF1000
And you could reduce the tank even further! :D
@@KitKitChanIsaac Lol nope, Harleys are slow asf
@@izzy031096 man I have all kinds of bikes from sport, adv, dirt, and cruisers. Even an old harley sporster pushing 50hp for its weight is still faster to 60 than a lot of cars on the road. But there is always children that don't ride that post about something they know nothing about.
Actually diesel engines came a long way. I'd expect a diesel motorcycle would be quick
We have the technology to put a diesel in a motorcycle now
I think the reason diesel didnt catch up is that all these emission devices you need to install for the motorcycle
Imagine a DPF and another separate tank for ad blue
Putting a dpf on a motorcycle seems pretty much impossible. Can't imagine there's a safe way to sneak a 1000 degree exhaust on a bike.
As long as it doesn’t reach 25hp it doesn’t need any emission stuff on it, I ride a crf250l with 17hp so honestly I think with today’s technology diesel is a very viable option for a fuel efficient bike
Yeah, that silly emission standard kill diesel engines
Motorcycles are barely emissions tested lol what are you on? They’re a different category entirely
There's no way Jeremiah was born in 2001. I refuse to believe it.
maybe 2000
I feel he was born in 1997
Holy shit I know right
So what, he is 19 to 20 years old? He looks 34 tbh. How could he have spent "way too much time and money on bikes losing friends and girlfriends if he is barely old to drive. It's gotta be a joke
Not possible
As a longtime rider familiar with how gasoline and Diesel engines work, it’s never occurred to me that putting a diesel in a motorcycle would be a good idea, for all the reasons you covered plus one you didn’t: heat. I think having a diesel between my legs would be like sitting above a cast iron stove. You brought up an amusing question so I watched for fun, and I think you did a fantastic job explaining all the issues clearly and concisely.
Imagine what happens if you get a combustion feedback loop ( runaway diesel) on a bike too. :)
