This Changes EVERYTHING 

Would the diesel version have any significant weight penalty? It seems there wouldn't be a rev limit issue for the diesel as the rotor doesn't have to reciprocate... I would think it would be superior if using modern diesel injection technology. Huge combustion pressures and high revs...

Diesel would be nice as an Axillary Power Unit for military vehicles that use diesel, and petrol for the same. APUs seem to be the way to go for powering warfare electronics and climate contol instead of having to run the fuel-hungry main engines.

I am sorry but Adept Ape on youtube made a video disproving this engine as a diesel engine, using their own facts against them. p.s. he is a CAT diesel mechanic. Here is the video I am referring to: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-K0Hn4EK9pkk.html

@@JoshKilen he doesn’t disprove the fact that it can run on diesel, but just raises doubts on whether it will meet the torque requirements that large diesel engines typically make use of. He questions whether it will be suitable as a direct replacement for large diesel engines with high rotating mass and torque, but doesn’t land on any concrete answers. Even if they can’t be used specifically for that purpose they will still be excellent in other applications due to their low weight and high power density.

Rob Dahm collab?

One man, one RX-7... and four liquid piston rotors. It's gotta happen at some.point surely!!

You already know some mad scientist is making one in his garage. Probably the same guy who made that 4 rotor in his garage lol

Never. Theyve had twenty years to bring an engine to market, havent sold one.

Yeah, I'd love to have this for that job exactly. It can run on all sorts of fuels (like say vodka) giving you fuel flexibility, it's low weight for its performance so it's not much worse than a pure electric car in that sense, and it's fuel efficient, so you can get some pretty good range with it. Adding to that the low number of moving parts and therefore high reliability... Yeah, this sounds like a dream.

When these come out i can use all the 2 stroke oil in them!

Good ideas....motorcycle..generator...hybrid car.. Gyrocopter.

I belive the issue with rotor temperature could be fixed using ceramics if I recall corectly we can make coats capable of withstanding such heat cheap, wouldn't it ? and if the freshload heats up isn't that good for carbon buildup ?

​​@@bigdaddyyute6472coating something with ceramics wouldn't do anything to solve the heat expansion problem. Ceramics just can handle heat better. What the person is talking about is how as an object is heated it changes the geometry of the object. However because the part that is rotating is the geometry of the piston itself any changes can impact the seal which will impact the efficiency. Which means you want something with extremely low size change within the normal operational specs of the engine. However, this causes an issue with the heating/cooling cycles. As cold air will rush into the engine making it smaller and then as you heat the air hot air will make it bigger this is also happened at extremely fast speeds. This is why you have expanding piston rings in a conventional cylinder engine. Meaning this engines will have to have insanely good tolerances and likely be individually tune. Also another major issue is going to be engine contaminant buildup which will literally change the piston geometry. How much this efficiency changes over time would be interesting to see. It still has apex seals it has to no metal to metal connection will ever be exact across different temperature ranges. Hell even think about just cpu/cpu coolers. They are of relatively similar metal types and almost the exact same temperatures but you won't get very far without thermal paste. I noticed that they only said up to 20-50%. Another thing that bothered me is they compared fully assembled engines with starts, spark/glow plug components, and full tanks compared to just the engine itself in size.

...But then the gas tank needed would be too heavy...

All these liquidpiston engines are either premix or oil injected, these do not require any oil filter or changes

Even better for a glider aircraft. Would be enough so they could take flight with out the need of being towed into the sky. Check out the plane with twin turbo V6 engine (in case You haven't)

Outboard motor for a boat

Or for hybrid vehicles like a tank. Size it up, make it diesel, and viola. Tanks need to go hybrid so they can run in a sort of stealth mode where they can at least hide their thermal signature. Being able to shoot first matters more these days.

@@dianapennepacker6854 most tanks are multifuel. Can switch to whatever u feed it. Got turbine engine

@@superliegebeest544 Sure and that is great and all. I wasn't talking about anything to do with fuel consumption. I was talking about it makes perfect sense to have a hybrid vehicle, because it is easier to mask your thermal signature. Thermal cameras are only getting cheaper, smaller, and better. Being able to hide from it is amazing. Also you get more torque and they are so much quieter. You can hear some tanks coming at ya from over a KM due to how loud those engines are. Just makes sense to pay more and deal with the extra complexity.

I was wondering that too, watched another vid and they didn't mention the torque specs either. Would love to see a legit dyno run

Very low eccentricity of the output shaft, therefore little torque. Just like the Wankel. Will they still cheat on the true displacement of these engines?

This will probably be their first use in cars, and they’d be very well suited to that application. Using a 30-40hp range extender, a large fuel tank and a small battery pack you could get unparalleled range and fuel efficiency without sacrificing on power. It’s the best of ICE convenience and energy density paired the efficiency and power of an EV. Plus without needing such large batteries and fewer engine parts they could be much cheaper. People would snap these up like nothing else.

Because everything is about money.

😊

it was actually 65-69 (oak ride thorium molten salt reactor) but I agree

Thorium was abandoned because there was no waste that could be sold to the military.

They originally where planning on actually using a liquid based piston, but abandoned the idea.

Overunity homopolar generator and the neutrino power cubes generator can tap the aetheric ZPE and power your car or what ever you want, not more batteries to charge and charging stations eliminated. i just see the obsession with dangerous heavy batteries or the grid

In such a way that if one rotor fails, you only loses ten percent power and can continue driving. At the workshop you remove the faulty rotor and just install a new one.

That is the common way to get more power in industrial applications, often you have a new crankcase and longer crank or, as Deutz did for many years, ability to bolt multiple engines together to make up to 16 cylinder inline (or V with new crankcases). Each cylinder was about 800cc. I remember a co-worker telling me about one that had run continuously at a mine in Africa for around 17 years, even oil changes were done on a running engine (being a diesel it wasn't particularly high rpm but did produce an incredible amount of torque)

Their website says the engine can be potentially scaled to anything between 1 and 1000+ HP. This guy claims it’s unlikely these will ever be used in cars but I’ve read that further down the line they are aiming for consumer vehicle applications as well. This engine would be especially useful as a generator/range extender in a Hybrid EV, but I can also see them being scaled up for use as the primary power train in sports cars, though that might take much longer. Once they’ve fulfilled their military contract obligations and perfected their designs I believe the first public markets they’ll try and break into will be generators, handheld tools and garden equipment. After that, likely HEVs, then probably motorcycles and finally sports cars, though this is just my estimation. They won’t be producing the engines themselves, they will be licensing to other manufacturers, so all of this will rely on other companies being willing to adopt the design. But if it’s as good as they say and they prove it with their military contracts I can see other manufacturers being keen to get their hands on this innovative technology.

That's probably the issue with this engine. Something isn't right the diesel engine show is only 40hp? Could be but it's an industrial engine, not a car engine. So build to last and probably tons of torque if u see that huge flywheel housing.

I would take the 2 strokes version as 4 strokes suck in trucks.

Probably just needs more testing. It's pretty new. They have the attention of the military, and other companies, so maybe it's just a matter of time before it becomes mainstream in something like generators or small aircraft.

If the first one was terrible, why did you buy a second one ?

@@sking2173 One, I didn't buy them consecutively. Two, i have also had bad traditional engine vehicles. Three, the second one wasn’t expensive..

Does the coyote have an oil injection system and can it run mounted in any position?

@@jlo13800 could be but that wasn't a well point of the engine. Power to weight is what was mentioned.

Size as you increase size you increase the rotational mass which will decrease the overall efficiency. It would be better to stack them like the dude does when he stacks three wankle engines together, but then you're going to start having massive cooling issues because the cooling system is mounted on the rotational portion. It's also air cooled. This is a really cool "toy" but I have severe doubts it will go very far. There are some critical issues that they have to overcome from a longevity perspective that seems unlikely to make this engine work over long periods of time.

As a 2 stroke it makes plenty of torque!

Yeah and 2 stroke oil injection too, no oil changes required!

relax...the engine on the left is a Isuzu c201 made for use in generators and pumps, it's naturally aspirated 4cyl designed before 1990 and makes 34hp at 2200 rpm....if I am not mistaken it is 1.6 liters (97 cubic inches),the engine is not "massive"...they weigh around 625 lbs. :-)

Its a 2 stroke that self supercharges which the XTS 210 does.
