Sounds similar to experimental designs by Rolls Royce for a diesel rotary during the 60s, in that it uses two separate parallel shafts and rotors for intake/compression and ignition/exhaust. > In the case of the Rolls-Royce Wankel Diesel, the fuel-air mixture is first compressed by the lower rotary, and the output of that engine (which would be like the exhaust valve of a conventional rotary) sends the compressed diesel/air mixture to the intake of the smaller upper rotary engine, where it’s compressed to ignite like a regular diesel engine. Seems like it had the same issues that have always plagued rotaries, primarily with apex seals. https://jalopnik.com/this-might-be-the-weirdest-engine-rolls-royce-ever-made-1797954082 https://jalopnik.com/this-might-be-the-weirdest-engine-rolls... https://youtu.be/1pDjwaqU0dU https://youtu.be/1pDjwaqU0dU
