So, How Does It Work? The Wankel Rotary Combustion Engine Theory, Design, and Principles of Operation Internal combustion engine: fuel air mixture ignites and the explosion directly drives the engine internally. Four phase Otto Cycle engine: intake, compression, power, exhaust. Three main moving parts in most RC engines: 2 rotors and the e ...

... it is an Otto Cycle engine. Unlike the conventional piston engine, the fuel air mixture is swept along, so the four phases take place in different areas of the engine. This turns out to be an advantage for Hydrogen fuel. Java Demonstration of RC Engine Cycles (about 104 KB) There is a 1/5 scale model "Visible Rotary Engine", available from D and J Hobby and Academy (and undoubtedly others). There is also a .30 model Wankel engine from OS / Graupner. Rotor, Eccentric Shaft, Peripheral Housi ...
