I was a Mazda service manager at a dealership back in the day, and the biggest problem we saw with the RX7's was that the owners babied them. They didn't run the engine at high enough RPM's to clear the carbon build up on the original 7 piece apex seals. When they got towed in all locked up, my head shop mechanic would break them loose with a wrench, get them started running really roughly, then literally put a brick on the gas pedal and go to lunch. They would blow huge clouds of smoke for a while, then start to smooth out, then gradually clean out and end up running great! I might have already sold the customer a new engine, only to find out the engine now ran just fine. Saved the owners a lot of money!

Water worked really good for breaking up the carbon. I had a 12A that was babied its whole life, and it was all sorts of carboned up, got a gallon of water, put a water injection jet on a hose, and held it at 4 grand spraying at 2 second bursts. I was amazed how much carbon literally came off of this engine. I stuck a camera in there and it was nearly spotless.

You'll be glad to hear that I was frequently running my first gen Rx7 near redline.

I inherited a 1980 RX-7 with a rotary engine soon after starting college. I'd worked on tons of 60s and 70s cars at that point in my life, rebuilding about 30 engines. I had no idea what or how rotary engines worked so I ask my Math professor and he sent me directly to the Engineering department. I was lucky enough to talk to two professors who were also rotary engine owners and fans of the technology. After a few talks they both strongly suggested I switch my course of study from Math to Engineering and I did just that. I had an amazing career as a mechanical design engineer working for NASA, the DoD and other Aerospace firms across the country and around the world. I have the rotary engine to thank for all that.

Geometrically :very high compression ratio, but achievable depends on the seal leakage. They were not able to obtain compression ratios to achieve compression ignition, For the demonstration the use methane and spark ignition. The real problem is the peripheral face seal at the corner designed to seal the front and rear walls. The problem Cooley had after he invented exactly this in 1903. Incidently, Cooley also had a two and a four lobe design, later expanded with 5, 6 and more lobes.

Erik, The mathematical treatment for the ideal trochoid is simple, as far as displacement is of interest, The rpm is limited by the structural design of the seal, where the inflection is hard to stiffen due to the centrifugal load.

Sort of yes, except that the Wankel housing really is peanut-shaped, meaning bigger at the ends than in the middle (it's technically a two-lobed epitrochoid), while this rotor is a simple oval (semi-circular ends connected by straight sides). Similarly, the Wankel rotor can be a simple Dorito-like triangle (although in practice the sides are usually circular arcs, which is a Reuleaux triangle, to increase the compression ratio), while this engine has a rounded three-lobed housing. They're related, but not the same shapes.

@@jfisk60903 Not necessarily, but they do have an uphill climb in this emissions-paranoid era. It is possible, with the right oil and a good catalyst, to meet the stringent (ridiculous) emissions requirements in place in many places today even with an oil-burning engine. It likely would be a somewhat expensive oil. However, in areas that test emissions, using the wrong oil will cost you big money as you'll ruin the catalyst and they'll make you replace it or stop driving the vehicle. All that translates into a vehicle which will be niche, but rotary engine vehicles have always been niche.

Rotary engines are just a poor engine design. Even in situations where reliability is not a factor traditional piston engines are superior. Look at drag cars. The engines in them are rebuilt after almost every run. They still choose to use traditional engines because they work better.

@@jfisk60903 this engine does not consume oil as part of combustion. It is metered directly to the sealing surface from the engine block, whereas a Wankel has to inject it into the combustion chamber or pre-mix with the fuel. They have oil consumption down to 4-stroke piston levels.

Magnificent work!

Excellent slow motion photography , you can actually see the answer to the apex seals being destroyed .

It's not a new cycle, just another rotary piston engine configurations. It does intake, compression, power, and exhaust just like every other four-stroke engine (including the Wankel/Mazda rotary).

I think I've seen a gif of this type of rotor years ago! So cool to see it as an actual thing!

That was truly awesome to watch.

Oh man... I've been waiting for this since you teased it in the community post! :-D

Kudos for showing engineers in our natural habitat -- desperately trying to finish up. :-)

Awesome engine design and idea. Very exciting development!

Brilliant! Thank you Warped Perception for sharing this video on Liquid Piston X Engine. Greetings from Madang, Papua New Guinea!

This new rotary configuration is extremely interesting and I cannot wait for more advanced prototypes.

I want one. I gotta say I really like this take on the rotary engine. The way liquid piston rearranged the rotor, chamber and seals is pretty intuitive. I thought the original design was perfect but I was wrong. I need one of these for my scooter.

No surprise but still and always an AWESOME VIDEO!

So excited for this.

I remember back in the early 80s machining a glass cylinder head for a singly-cylinder piston engine so that we could fire a Laser Doppler Anemometer into the combustion chamber to 'measure' what was going on inside. This was before computer modelling etc. and it was the very early days of research into exactly what was happening inside a firing piston engine. We built a rig to traverse the 'laser measurement volume' in three dimensions across the combustion chamber to a few degrees before and after TDC. We fed the data into an ICL 2960 mainframe to process the data to give us a chance to 'visualise' the air-flows inside, before and after ignition of the fue;/air mixture.

That thing looks so crazy,! I'm glad I seen this

Great team work make great things .

Just insane to see that RPM from it in action :D

I've been waiting for liquid piston to finally get to market. I've been checking in on their site on and off for years now. The reduction in weight is incredible. 1hp per pound is pretty incredible for a four stroke.

Excellent video, more please and well done to the engineers

Great job Sir! Thanks for sharing.

@ujiltromm7358

The most important aspect of this engine IMO is that the apex seals aren't pushed against the walls of the engine from the momentum imparted by the rotor, unlike in a traditional Wankel. This is huge for reducing wear.
