So, How Does It Work? Wankel Rotary Combustion Engine (RCE) Theory, Design, and Principles of Operation Internal combustion engine: fuel air mixture ignites and the explosion directly drives the engine internally. Four phase Cycle engine: intake, compression, power, exhaust. Three main moving parts in most RC engines: 2 rotors and the eccentric shaft. These rotate continuously in a single direction. They do not jerk backwards and forwards. These are surrounded by the peripheral housing where the …showed first 75 words of 787 total…

There were also designs by Pappenheim, Hornblower, Murdoch, Bramah, Flint, Poole, Wright, Marriott, Trotter, Galloway, Parsons, Roots, Wallinder, Skoog, Baylin, Larsen, Ljungström, Behrens, Maillard, and Jernaes. Marsh has made a good summary with diagrams. Wankel engines use cycloidal gearing, an old and unusual form of gearing used in watches, Roots blowers, screw compressors, and pumps.
