Development of Rotary Internal Combustion Engine

German engineer Felix Wankel developed the rotary internal-combustion engine in 1954-56 while at the NSU Motorenwerke AG in Neckarsulm, Germany. Wankel replaced the reciprocating pistons and cylinders of other engine designs with a rotor shaped like a curved equilateral triangle. The rotor engine turned creating three chambers of dynamically changing size and cycled through intake, compression, expansion, and exhaust taking place in each chamber. The output shaft provided power through the rotor.
