I was doing a patent search on Jim’s “new” patent in which the vanes are moving in and out from the center of the engine toward the outer edge. But Liquid has a rotary design similar to the Wankel. What these Russian inventors claim is the use of a different kind of compression theory.
“High Efficiency Hybrid Cycle’ (HEHC) attempts to combine the best features of numerous thermodynamic cycles including Otto, Diesel, Rankine, and Atkinson to create a highly efficient engine.”
This is very similar to my ‘idea’ in that with the proper design technique one can control the combustion process down to the molecular level.
