This is geometrically an inverted Wankel engine that operates on the high-efficiency hybrid cycle. [1] [2] In the Wankel, the only successful pistonless rotary engine to date, a figure-eight-like epitrochoid housing surrounds a curved sided triangular rotor. The rotor revolves around a fixed gear in a hula-hoop motion. The output shaft revolves ...
