Inspired by: Quasiturbine rotary engine: welcomes most fuel and hydrogen !
Possibility of surpassing the current supremacy of Piston and Wankel engines by creating without any eccentric crankshaft, a new type of unconventional 4-stroke continuous combustion low RPM and high torque turbine-like, clean and efficient and HCCI or photo-detonation compatible. In this Quasiturbine the active pressure acts only tangentially on the periphery contour shape modifiable independently of the rotor (without radial displacement and without the flow prejudice cause in Piston and Wankel by acceleration inversion during stroke).
For each engine type, the 4-stroke 2-rotations Ratio of " Intake volume to external engine volume " (the engine power density) is:
Single Piston 10%;
Single Wankel 42%;
QT-SC 67%; and
QT-SCLimit 160% (intakes more than its external volume!).
