These babies are supposed to surface this year for applications such as EV range extension and military field generators and such. But I am thinking they would be perfect for the ultimate high mileage RT. With a bit of luck we will see such applications in years to come. They claim that the machining of this engine is very simple. Would it not be great if they were something that was produced by many different machine shops, like the AR type rifle is? Once more, if what they claim on their site is true, it would be hard to understand why such liscensing agreements would not develop. I want one. www.automotiveworld.com/analysis/96647-us-liquid-piston-launches-x2-rotary-diesel-engine/No I do not have any monetary interest in this engine, just an automotive interest.

It looks like a single Wankel type Rotary. VW owns the patent on the Wankel and Mazda must license it from them. The funny about that is in 1979-1989 the RX7 was spanking Porsche 924's so Porsche made the Turbo 924 so Mazda made the Turbo RX7.
Looks promising for sure.

That's a lot of claims! You would think if this motor lived up to the hype, investors would be lined up to hand them $20 million. What's the hitch? It could be patents and intellectual property infringement issues, but the motor looks distinctly different and even runs on different fuel than the Wankel rotary motor. I think it is more a case of squirrely numbers and no real world prototype to back up the claims. The one picture they post is an incomplete block and set next to a monster diesel motor, leading us to believe the little rotary can do the same work as the big boy... I'm not buying it.

<<<SNIPPED>>> but the motor looks distinctly different and even runs on different fuel than the Wankel rotary motor. <<<SNIPPED>>> The one picture they post is an incomplete block and set next to a monster diesel motor, leading us to believe the little rotary can do the same work as the big boy... I'm not buying it. This whole design in that article is all based on misconceptions and embellishment of facts. There are no real dyno spreadsheets or any videos of this engine running. If you read all the other articles and the many comments it seems like all Venture Capital hype, kind of like what I am seeing with Eliomotors.com , VC HYPE!!! Agreed that little rotary could not put out the power of that HUGE diesel. But if you were into Rotarys back in the 70's like I was you'd know you can get a lot of power in one rotation of a Wankel. It runs like a 2 cycle in the respects of a power cycle in one 360 degree rotation (times 3 ports per rotor, times two rotors), where-as a 4 cycle takes 720 degrees for 1 power stroke. As the rotor rotates a leading seal uncovers the intake port, then as it continues it draws in the air/fuel mix, then as the trailing seal shuts off the intake port, compression and then spark, POOF, then the leading seal uncovers the exhaust port.... The standard engine in the RX7 was just 1150 cc or 70 Cubic Inch, Output was 110 HP. A company called "Racing Beat" did a lot of development on the Mazda licensed version of the Wankel. They built a single rotor for NASA that pumped out about 200 HP. They also made one to run on diesel. But they found that a rotary did not like much more than 9:1 compression running on GAS. But put a TURBO on one and WOW! I ran a BRE Turbo setup on my 79 RX7 and was kicking out just under 255 HP. I then built a 80 CI (1308cc) and it made 300 poneys. I had that in the car whey they deployed me to Germany. OH BOY, perfect Autobahn runner, until I priced the INSURANCE for that car in 1980, $2000 per year.
