The Two-Stroke Rotary Engine for Start Systems and Small Planes 1999-01-1380
An innovative rotary engine uses a rotor that executes pendulum-like oscillatory rotation. This is converted into uniform rotation of the drive shaft by a simple mechanism. The new design is compact, lightweight and powerful. Simpler and cheaper fabrication, lower levels of noise and vibration, easier maintenance are among its advantages over the Wankel rotary engine and the Otto piston engine.
