I still can’t quite wrap my head around how such a small engine can produce so much power. A conventional piston engine of similar overall size would be for large RC models, not a full size go kart. Granted, it’s not setting any speed records, but the fact it moves at all is seriously impressive. If LiquidPiston plays their cards right, this could be a revolution
4 stroke piston engines needs 2 up and 2 down strokes to make 1 power. Whilst this thing, 1 rotation makes 3 power. 1:3 compared to 4:1. Factor in mechanical losses of the up and down losses for pistons.
From what i could see this engine only drives a generator. Bet they had to little juice stored on the battery for that first run. The concept is interesting for sure but more work needs to be done here. I wonder how large that engine will have to be to be able to move an ordinary sized passenger car...

I said the same thing. Permanent magnets are the best, but apparently notoriously difficult to control (sync with the engine speeds). Permanent magnet motors are higher efficiency motors, that are best used as a generator only. I believe Honda uses them. And have a cog that allows some of them to rotate at speeds of up to 18k rpm. They are much smaller in design than even the liquid piston. Excess power can be stored in a battery. But all this will make the design unnecessarily complex and expensive.
An inline motor would be regenerative like an alternator but instead apply voltage to it and now the shaft rotation/torque are improved. You are in that case helping spin the crank. Power booster. Now make this motor/alternater also be able to draw in air while rotating to boost fuel-air mix pressure and you have a motor booster, a pressure booster (al electric supercharger of sorts) and when not driven, you get alternator and furl intake pressure boost (supercharger effect...boost intake pressure)

The exhaust back pressure losses from a turbo is much lower than any electric drain on the engine to push a turbo/supercharger, as the turbo/supercharger needs to be active all the time.

As such, it will be more comparable to a supercharger, which always has worse fuel economy than a turbo.

It ain't the future. You could use the electricity ti charge a battery and then power an electric motor at 90% efficiency. Or you could use electricity to electrolyze water into hydrogen gas at a 50% efficiency at best, use more electricity to compress it so you can actually store it, use more electricity to get it to a filling station and then burn it in a combustion engine at maybe 40% efficiency. So all in all you could drive somewhere in an EV or you can spend 6 times as much to drive to the same place in the same vehicle but this time it's powered by a combustion engine burning hydrogen.
The energy density in hydrogen is, well unbeatable for a chemical reaction and the waste products of the reaction are always clean. Cool thing is, you could fuel both direct combustion and electric generating hydrogen engines at the same station and the fill-up takes roughly the same amount of time as gas. I really hope silly subsidies stop positively discriminating battery powered transportation and instead give chance to other clean alternatives, that don't have the many disadvantages of batteries.
Be aware that the fossil fuel industry is subsidised globally by $600 billion (6x10^11 US dollars) per year. Counting all of the indirect subsidies and benefits in kind, it adds up to around $3 trillion (3x10^12 US dollars) per year, globally. The subsidies on electric vehicles are tiny in comparison.
I think the hydrogen toyotas that aren't racecars don't use direct hydrogen combustion. It uses cells which create electric in a similar way to how electrolysis works. This creates electric also water as a waste product only. The charge created then drives electric motors
An engine running on gas or diesel produces water as a by product too. It comes out as steam and will just float off. A little might condense while the exhaust is cold, but it's really a non issue.
It may be slow, but it worked. That's where you learn. The belt clutch was possibly holding it back without the rpms needed. Tune the drive train I'd like to see more on it.
I love when the engine runs on beat with the music in slow-mo. Awesome. Such a beautiful piece of engineering. Should this machine enter mass production, I would have one instantly!
Hydrogen + rotary = EPIC LiquidPiston: Thanks for bringing it to life, serious potential. As an armchair enthusiast, I've had a very similar idea but obviously no way to bring it to life. Warped Perception: Thanks for filming. The more publicly these alternative technologies are covered, the more likely they are to succeed. I'll be investigating the LiquidPiston further thanks to your content. 🙂👍 I love the elegant engineering to combat the typical detonation hot spot that wankle engines have (because of one combustion chamber) AND the geometry of the rotor itself to compensate for the difference in quenching distance for hydrogen. Thank you for including the slow motion of this combustion process, amazing eye candy. [Perhaps consider an edit with gasoline comparison (acetylene was nice, but different visually than gasoline) to show the huge difference in flame speed and quench distance between the two fuel types?] I'll be waiting with anticipation to see LiquidPiston's future iterations of this project and the potential for eventual improvement beyond petroleum. BRAVO👏 Edit: subscribed and found the previous video "See Thru Liquid Piston Rotary Engine - in Slow Motion" of this motor design running on gasoline. 👏👏)
I think its great when people keep trying to innovate and make idea's that were once considered impossible in to a reality and actually making it, Technology can be dangerous, but so can a piece of paper, all depends if you use it for the right reasons, This is awesome thanks Liquid Piston and all at WP 🤘🏴👍
HEll YEA I wanna see engines that sound good while being eco-friendly so that not all the cars on the road would be silent. Electrics are great but having these would be nice too.
@@jlo13800 Sarich is long gone. But on 2 stroke jetskis we use a full synthetic oil. It lubes perfectly without burning away and comes as oil out of the muffler.
That sounds like the EMD16-645 2 strokes on the boat i work on and the detroits also. oil comes out of the exhaust if there is not enough load on the engines.
I'm unsure of this liquid piston engine. They boast of how efficient it is, and how much pound for pound power it can produce, but every time I see one running there's always some electric motor involved, which is causing me to doubt it's actual output.
I completely agree. This one doesn’t make much power and probably doesn’t have much torque either. It’s very small and impressive but i believe it should have done something different.
If they were touting this as the final product I'd be skeptical AF. This isn't even the prototype though... they're still in the R&D proof-of-concept stage.
@@andie_pants i do agree, however claiming an engine is "running" when it is possibly not and just being spun by a electric motor with fuel being thrown in to cause a few bangs would hardly be considered running or making power by any means. when i see one run unassisted by an electric motor ill be more open to the idea that this engine design is actually plausible.
I love how this sounds like a Triple cylinder motorcycle engine! The adaptability of fuels in this engine config is just brilliant. You can run it on Petrol, Vodka, H2 and even diesel. ❤
That's insane! Really lets you believe rotaries aren't dead yet, and if they're getting it to run on Hydrogen... Ah, the possibilities! Also can we take a moment to appreciate how good it sounds?
I'm very skeptical that hydrogen fuel will ever take off practically because it's just too hard to produce and store and is incredibly dangerous in the event of a tank breach. Thankfully this Liquid Piston engine can run on loads of different fuels. I've seen it run on propane, gasoline and diesel, as well as hydrogen now, so it is plenty flexible enough to remain relevant even if hydrogen doesn't take off
Nice touch timing the firing to the music. I'm curious if the exhaust should point down instead of up for water evacuation. Back pressure from the fuel burn might have water collecting in the upward facing exhaust plumbing? 👍 😃
The water doesn't condense in the pipe, the reaction product is gaseous water (steam) and any cold start condensation will quickly boil off from exhaust temperature. Hydrogen runs really HOT. You can't play with the stoichiometric ratio of H2 to O2 as you can with liquid fuel and oxygen. If anything you have to run it oxygen rich to reduce power of the stroke. If you run it H2 rich, you'd have a constant flame from your exhaust(and melt the tip of the pipe) as any hydrogen left in the exhaust product will immediately react with the atmospheric oxygen.
*_A new rotary invented engine with the future of fuel powered engines... This is crazy. Liquid Piston is doing amazing things!_* Hopefully this can be on a full sized car soon.
@@alexzanderroberts995 *_There are plenty of fully blown 2 rotor drag cars that run 6 seconds at the quarter LOL_* :c it's pretty crazy. Not allot of torque but the original rotary engines are crazy fast when modified. *I just wonder how the future will look for these new invented ones.*
@@rjaybruhh the issue is consistency, and reliable torque. You cant exactly tell my those cars are reliable. We dont exactly know the reliability of these engines yet, so I assume the apex seals tend to wear down. Edit: I am not talking about future designs, as they will be better in every way, I am talking about this engine right here.
Something tells me its fake. Even when working, you can see the electric motor start to spin and propel the kart before the engine rev up. That kart is moving on lipos, and we can't know how much it's the engine recharging them.But seems like even the engine is moved by the electric motor, at least at the low rpm range. At this point, i need to see that engine working standalone, without even the dyno. You can see on the dyno footage that the engine is reved up before the ignition starts. That thing is smelling worse on each video. Sorry to all if I'm wrong, but they need to expect some skepticism and provide some proof like the engine working alone. They know it, and avoiding doing so seems suspicious. i really hope I'm wrong.
@@xiro6 Yeah every time i see these engines they are connected to something that looks like an electric motor. I don't understand why it is never run just setting on a test stand without something connected to the output
@@xiro6 Nah you're right, it smells like many other investment scams. But even if it works, it's probably way too small to power things any other way, or they can't get it to run at a lower RPM. Cool little thing, but I'd bet they're greatly exaggerating the power it makes. Hopefully I'm wrong, but it's just too much like every other bunch of bull for me to trust it yet.
@@glennmagnus854 My guess is that when they are connected to an electric motor, then they can run at the best rpm for peak efficiency at all time and waste less power to heat. It's the very reason the Wankel rotary was considered by Mazda as a range extender for their electric vehicles.
This is far more ground breaking than most can conceive. The liquid piston technology puts solar, wind, nuclear and fossil fuels in the rear view mirror
@@tony_5156 the CVT transmissions on go karts (the one seen here) has a built in clutch. However it is made to be used on gas engines so it engages at 2.5-3.5k rpms. This is way too low on this engine's torque generations curve.
When it comes to Wankel rotaries (triangular rotors) oil is commonly added to the fuel which lubricates the rotor and apex seals then burns off during combustion, just like a 2 stroke engine you’d see in a line trimmer or chainsaw, but with the liquid piston, I have no idea. I only really understand liquid fueled systems, so I’m not sure about the gas either.
Since the seals aren't rotating, they could pump lube in through one side and out the other. With the see through plate provided by Warped Perception, this would have been ommited.
I thought Hydrogen powered internal combustion engine have a ridiculous yield compared to hydrogen cell. Remember that hydrogen is like a battery, it needs electricity to be produced and we don't find it naturally like oil. It's still cool tho and i'm not a fan of electric cars but i don't see the point of doing this exept the "because we can"
yes.. because we can... just a funny project, hydrogen combustion wont make it to market, it has even worse efficiency than fuel combusiton.. and many other issues..
Imagine not being a fan of EV when it's already better than ICE, faster in motorsport, easier to work on, and is more fun to drive then ICE. You must be boring at parties.
@@sqlevolicious They are lame AF to drive, has no gearbox to play with, no clutch, no heels and toe, often more than 2 ton to move around and brake, all sound the same and you can't do a trip with it. They can be easier to work on IF the manufacturer let you so... Faster is not always better, you must be boring for your gf
Reminds me of an oil sump impeller. Ovoid shape. Three ignitions per revolution jacks the power significantly. Edit: I'm glad they're not afraid to test and put it out in public view. Great video.
If that thing made any power at all, even 5 hp, it wouldn't need an electric motor. You don't prove the concept of your engine by combining it with another power source to get some work done. Not promising. Haven't they been working on this thing for a while?
yeah seems pretty bullshit to me... anyone can strap a garden gas power generator to a battery and electric motor and call it a hybrid... they just did that with a hydrogen tank but it doesn't even need flame, it would do the same damn thing on the 500psi of pressure alone!
I think Hydrogen is simply too dangerous to carry around in a race car/kart. One crash, one puncture, and you take out half the circuit. There's a reason it never has been seriously considered for use in motorsports.
What a genius little motor! and now able to run on hydrogen! Welldone LiquidPiston - wish you all the success for the future! Thanks WP for a great video!
That was sad! But i think the clutch is major issues. If im guessing like wankel rotary they make monstor revs!!!! Probsbably/temperamental on bottom and ramps power fast!!!!!!!! So clutch actuation woul be crucial, cool motor
I can appreciate the danger aspect. Strapping a tank of hydrogen with flimsy tube near a 300 degree engine is always exciting times. Ride this thing enough times and they'll find 5 pieces of this guy
I look forward to seeing more about the Liquid Piston Rotary engine, but mostly as a Motorcycle Drag/Road racing engine, running on modern 2-Cycle premixed fuels, with zero Hybridology in the future. An inexpensive racing engine only has to last for dozens of hours before a re-build, and the Liquid Piston Rotary seems PERFECT for this purpose in every racing application.

An engine running on gas or diesel produces water as a by product too. It comes out as steam and will just float off. A little might condense while the exhaust is cold, but it's really a non issue.
The water produced by burning hydrogen is in the form of vapor. It is only liquid water after it cools, long after it exits an exhaust pipe.
Broooo that edit of the explosions with the song was amazing
Thank you
It may be slow, but it worked. That's where you learn. The belt clutch was possibly holding it back without the rpms needed. Tune the drive train I'd like to see more on it.
That transparent side by side was perfect for understanding the difference between the two engines, thankyou
If they ever make these for normal vehicles like Mazdas then I could see them being less of an issue and more of a new kink for car enthusiast
I love when the engine runs on beat with the music in slow-mo. Awesome.
Such a beautiful piece of engineering. Should this machine enter mass production, I would have one instantly!
Hydrogen + rotary = EPIC
LiquidPiston: Thanks for bringing it to life, serious potential. As an armchair enthusiast, I've had a very similar idea but obviously no way to bring it to life.
Warped Perception: Thanks for filming. The more publicly these alternative technologies are covered, the more likely they are to succeed. I'll be investigating the LiquidPiston further thanks to your content. 🙂👍
I love the elegant engineering to combat the typical detonation hot spot that wankle engines have (because of one combustion chamber) AND the geometry of the rotor itself to compensate for the difference in quenching distance for hydrogen.
Thank you for including the slow motion of this combustion process, amazing eye candy. [Perhaps consider an edit with gasoline comparison (acetylene was nice, but different visually than gasoline) to show the huge difference in flame speed and quench distance between the two fuel types?]
I'll be waiting with anticipation to see LiquidPiston's future iterations of this project and the potential for eventual improvement beyond petroleum.
BRAVO👏
Edit: subscribed and found the previous video "See Thru Liquid Piston Rotary
Engine - in Slow Motion" of this motor design running on gasoline. 👏👏)
1:34 i love the fact that the combustion is syncronized with the song 😂
I think its great when people keep trying to innovate and make idea's that were once considered impossible in to a reality and actually making it,
Technology can be dangerous, but so can a piece of paper, all depends if you use it for the right reasons,
This is awesome thanks Liquid Piston and all at WP 🤘🏴👍
😎🏴
Sounds like a twin-turbo v6 from an nsx na1 lol,its actually pretty dang cool🔥
Jerry Seinfeld - “the helmet is wearing YOU for protection”
HEll YEA I wanna see engines that sound good while being eco-friendly so that not all the cars on the road would be silent. Electrics are great but having these would be nice too.
Good to see work continuing. In Australia we had the Sarich rotary engine, sadly never got to sort out the full burn level. Keep it up guys!
What 2 stroke oil did you run in that? I use nothing but amsoil interceptor in my rotaies.
@@jlo13800 Sarich is long gone. But on 2 stroke jetskis we use a full synthetic oil. It lubes perfectly without burning away and comes as oil out of the muffler.
That sounds like the EMD16-645 2 strokes on the boat i work on and the detroits also. oil comes out of the exhaust if there is not enough load on the engines.
Yes the rotaries use the same 2 stroke synthetic oil!
Mad props for slowmo sync!
I'm unsure of this liquid piston engine. They boast of how efficient it is, and how much pound for pound power it can produce, but every time I see one running there's always some electric motor involved, which is causing me to doubt it's actual output.
Precisely
I completely agree. This one doesn’t make much power and probably doesn’t have much torque either. It’s very small and impressive but i believe it should have done something different.
Yeah and the engine was at like 8000 to 10000 rpm wich is enuth to engage that chluch a 50ccm piston engine can do that
If they were touting this as the final product I'd be skeptical AF. This isn't even the prototype though... they're still in the R&D proof-of-concept stage.
@@andie_pants i do agree, however claiming an engine is "running" when it is possibly not and just being spun by a electric motor with fuel being thrown in to cause a few bangs would hardly be considered running or making power by any means. when i see one run unassisted by an electric motor ill be more open to the idea that this engine design is actually plausible.
I love how this sounds like a Triple cylinder motorcycle engine! The adaptability of fuels in this engine config is just brilliant. You can run it on Petrol, Vodka, H2 and even diesel. ❤
Might be amazing to see thermal images of your see-thru engines.
The sync between the piston fires and the song was 10/10
That's insane! Really lets you believe rotaries aren't dead yet, and if they're getting it to run on Hydrogen... Ah, the possibilities!
Also can we take a moment to appreciate how good it sounds?
I'm very skeptical that hydrogen fuel will ever take off practically because it's just too hard to produce and store and is incredibly dangerous in the event of a tank breach. Thankfully this Liquid Piston engine can run on loads of different fuels. I've seen it run on propane, gasoline and diesel, as well as hydrogen now, so it is plenty flexible enough to remain relevant even if hydrogen doesn't take off
Matching the fire music to the firing order 🔥🙌🏽 epic
Nice touch timing the firing to the music. I'm curious if the exhaust should point down instead of up for water evacuation. Back pressure from the fuel burn might have water collecting in the upward facing exhaust plumbing? 👍 😃
The water doesn't condense in the pipe, the reaction product is gaseous water (steam) and any cold start condensation will quickly boil off from exhaust temperature. Hydrogen runs really HOT. You can't play with the stoichiometric ratio of H2 to O2 as you can with liquid fuel and oxygen. If anything you have to run it oxygen rich to reduce power of the stroke. If you run it H2 rich, you'd have a constant flame from your exhaust(and melt the tip of the pipe) as any hydrogen left in the exhaust product will immediately react with the atmospheric oxygen.
The music syny to the slowmo playback speed was absolutely on point. Bravo sir.
*_A new rotary invented engine with the future of fuel powered engines... This is crazy. Liquid Piston is doing amazing things!_* Hopefully this can be on a full sized car soon.
Probably not, it has way too little torque.
@@alexzanderroberts995 *_There are plenty of fully blown 2 rotor drag cars that run 6 seconds at the quarter LOL_* :c it's pretty crazy. Not allot of torque but the original rotary engines are crazy fast when modified. *I just wonder how the future will look for these new invented ones.*
@@rjaybruhh the issue is consistency, and reliable torque. You cant exactly tell my those cars are reliable. We dont exactly know the reliability of these engines yet, so I assume the apex seals tend to wear down.
Edit: I am not talking about future designs, as they will be better in every way, I am talking about this engine right here.
@@alexzanderroberts995 *_Trueee_*
*_THIS IS THE FUTURE!_* The people who made this are generous!
Making it a hybrid was unnecessary. Just coupling the engine to the tourqe converter would have been better. Over engineered and under performing.
Something tells me its fake.
Even when working, you can see the electric motor start to spin and propel the kart before the engine rev up.
That kart is moving on lipos, and we can't know how much it's the engine recharging them.But seems like even the engine is moved by the electric motor, at least at the low rpm range.
At this point, i need to see that engine working standalone, without even the dyno. You can see on the dyno footage that the engine is reved up before the ignition starts.
That thing is smelling worse on each video.
Sorry to all if I'm wrong, but they need to expect some skepticism and provide some proof like the engine working alone. They know it, and avoiding doing so seems suspicious.
i really hope I'm wrong.
@@xiro6 Yeah every time i see these engines they are connected to something that looks like an electric motor. I don't understand why it is never run just setting on a test stand without something connected to the output
@@xiro6 Nah you're right, it smells like many other investment scams. But even if it works, it's probably way too small to power things any other way, or they can't get it to run at a lower RPM. Cool little thing, but I'd bet they're greatly exaggerating the power it makes. Hopefully I'm wrong, but it's just too much like every other bunch of bull for me to trust it yet.
@@glennmagnus854 My guess is that when they are connected to an electric motor, then they can run at the best rpm for peak efficiency at all time and waste less power to heat. It's the very reason the Wankel rotary was considered by Mazda as a range extender for their electric vehicles.
@@xiro6 I've read some of the papers from MIT. Impressive. Especially with the targeted (and almost) 26:1 compression ration. They like it.
1:16 This very moment, when the motor and the song "Fire - ALIBI Music" meets the same beat. Love that !!!
This is far more ground breaking than most can conceive. The liquid piston technology puts solar, wind, nuclear and fossil fuels in the rear view mirror
Yeah especial if you powered with ZPE! A pulsed plasma rotary 2 stroke anyone.
syncing the firing with the music was EPIC
You guys don’t know anything about go-carts clutches this was a bad example
Clutch what clutch just gas and stop
@@tony_5156 i think hes talking about the cvt
@@tony_5156 the CVT transmissions on go karts (the one seen here) has a built in clutch. However it is made to be used on gas engines so it engages at 2.5-3.5k rpms. This is way too low on this engine's torque generations curve.
That music in sync with the explosion awesome
Hmm, yes. Use a high pressure hydrogen tank as the rear bumper. Nothing wrong with that.
As if they're gonna crash at those speeds, come on
Shhhh! ...secret weapon, the boom and zoom rear assault defence bumper
Smiles in Ford and practically every car manufacturer until 1985.
The sound is just amazing!
I'm confused. How does the engine lubricates?
When it comes to Wankel rotaries (triangular rotors) oil is commonly added to the fuel which lubricates the rotor and apex seals then burns off during combustion, just like a 2 stroke engine you’d see in a line trimmer or chainsaw, but with the liquid piston, I have no idea. I only really understand liquid fueled systems, so I’m not sure about the gas either.
Since the seals aren't rotating, they could pump lube in through one side and out the other. With the see through plate provided by Warped Perception, this would have been ommited.
Dude looks ridiculous in a helmet with something moving that slow!
Very interesting video! Your content is very high quality. Greetings from austria!
This engine is amazing, has so much possibilities. Also it sounds awesome, I’ll be waiting for more videos of this engine!
I thought Hydrogen powered internal combustion engine have a ridiculous yield compared to hydrogen cell.
Remember that hydrogen is like a battery, it needs electricity to be produced and we don't find it naturally like oil.
It's still cool tho and i'm not a fan of electric cars but i don't see the point of doing this exept the "because we can"
yes.. because we can... just a funny project,
hydrogen combustion wont make it to market, it has even worse efficiency than fuel combusiton.. and many other issues..
Imagine not being a fan of EV when it's already better than ICE, faster in motorsport, easier to work on, and is more fun to drive then ICE. You must be boring at parties.
@@Pyrcae thats what they said about EVs and cellphones, lol.
@@sqlevolicious They are lame AF to drive, has no gearbox to play with, no clutch, no heels and toe, often more than 2 ton to move around and brake, all sound the same and you can't do a trip with it. They can be easier to work on IF the manufacturer let you so... Faster is not always better, you must be boring for your gf
@@sqlevolicious so you truly believe that Hydrogen combustion market will be bigger than EV and todays fuel combustion ?
I need to buy an RX-7 and put one of these in it! Awesome work!
Let’s build something Hydrogen Powered for you 🥶☮️
Technology-wise quite impressive, performance was underwhelming. I know, I know, give it time to mature.
1:25 Beat synced to sparks, you definitely own your editor a beer for that pleasuring awesome nice edit!
"Here is how it's supposed to run"
Me: I could still run faster.
I need to see and hear a big version because that sounds so cool
I'd like to see your mini rotary on a weed eater.
I was thinking it would make for a mean chainsaw.
A rotary powered goat?
@@dass1333 that would be one "bAAAd" mamajama.
Reminds me of an oil sump impeller. Ovoid shape. Three ignitions per revolution jacks the power significantly. Edit: I'm glad they're not afraid to test and put it out in public view. Great video.
If that thing made any power at all, even 5 hp, it wouldn't need an electric motor. You don't prove the concept of your engine by combining it with another power source to get some work done. Not promising. Haven't they been working on this thing for a while?
yeah seems pretty bullshit to me... anyone can strap a garden gas power generator to a battery and electric motor and call it a hybrid... they just did that with a hydrogen tank but it doesn't even need flame, it would do the same damn thing on the 500psi of pressure alone!
I think Hydrogen is simply too dangerous to carry around in a race car/kart. One crash, one puncture, and you take out half the circuit. There's a reason it never has been seriously considered for use in motorsports.
That's a quite a Go Kart from my Go Kart I had 1958. It had a Clinton lawn mower motor and top speed was 30 MPH. I was 12 years old and I loved it.
That was comically underwhelming. A climax of disappointment. Haha
What's disappointing about this? It's a freaking hydrogen rotary powered go kart!
Lmao
What a genius little motor! and now able to run on hydrogen! Welldone LiquidPiston - wish you all the success for the future! Thanks WP for a great video!
What?! That was sick with the music syncing with the combustion. Who was the producer??
Loved when you synced the music with the movie
The sound of the rotary engine is just>>>>>
Super Cool!!!! Thanks for sharing, She sounds like a 2-stroke chainsaw biting into a BIG log :)
I like how you synced the music with the engine. Very cool
This Engine should be promoted to be in our vehicles, as it is so simple, easy to maintain.
Nice work By Warp Perception.
That engine is really cool. It has 3 ignitions per revolution and the small combustion chambers make it really easy to fuel and ignite.
Amazing edit, the flames of the piston in slow motion with the song! Also great content!
Wow. Just wow. What a set up. Yet again with something new, innovative, and educational.
That was sad! But i think the clutch is major issues. If im guessing like wankel rotary they make monstor revs!!!! Probsbably/temperamental on bottom and ramps power fast!!!!!!!! So clutch actuation woul be crucial, cool motor
Loving it. Haters are literally 12 year ol arm chair experts.I like how you manage to grow through the shit they throw, it's fuel to the fire!
you got my follow as soon as you synced up the combustions with the song.
I think that is way cool and green. I think it has a lot of potential. I can a lot of uses for it.
Im just going to say it those electronics are killing it!!!
I like that the engine follows the beat of the song
Anybody else hearing the 3 cylinder overtones in the engine note? Man engines are fascinating
Yes its a 2 stroke rotary and sounds like a 2 stroke triple.
This is the best sounding go kart.
engine sounds incredible.
It might not be very fast right now, but man does it sound cool! I love it, lol
This engine has got to be in a shifter cart !
We are getting soooo close to being a viable combination of drivable, and sustainable power !
I can appreciate the danger aspect. Strapping a tank of hydrogen with flimsy tube near a 300 degree engine is always exciting times. Ride this thing enough times and they'll find 5 pieces of this guy
Rotary motors are so interesting.
the editing is next level
that engine has the best sound I have ever heard
I look forward to seeing more about the Liquid Piston Rotary engine, but mostly as a Motorcycle Drag/Road racing engine, running on modern 2-Cycle premixed fuels, with zero Hybridology in the future. An inexpensive racing engine only has to last for dozens of hours before a re-build, and the Liquid Piston Rotary seems PERFECT for this purpose in every racing application.
Quite an accomplishment. More, please.
