[PAR] [TLE] Wankel engine [SEP] The Wankel engine is a type of internal combustion engine using an eccentric rotary design to convert pressure into rotating motion.  In contrast to the more common reciprocating piston designs, the Wankel engine delivers advantages of simplicity, smoothness, compactness, high revolutions per minute, and a high power-to-weight ratio primarily due to the fact that it produces three power pulses per rotor revolution compared to one per revolution in a two-stroke piston engine and one per two revolutions in a four-stroke piston engine (although at the actual output shaft, there is only one power pulse per revolution, since the output shaft spins three times as fast as the actual rotor does, as can be seen in the animation below, making it roughly equivalent to a 2-stroke engine of the same displacement; this is also why the displacement only measures one face of the rotor, since only one face is working for each output shaft revolution).  The engine is commonly referred to as a rotary engine, although this name also applies to other completely different designs, primarily aircraft engines with their cylinders arranged in a circular fashion around the crankshaft.  All parts rotate consistently in one direction, as opposed to the common reciprocating piston engine, which has pistons violently changing direction.  The four-stage cycle of intake, compression, ignition, and exhaust occur each revolution at each of the three rotor tips moving inside the oval-like epitrochoid-shaped housing, enabling the three power pulses per rotor revolution.  The rotor is similar in shape to a Reuleaux triangle with sides that are somewhat flatter. [PAR] [TLE] NSU Delphin III [SEP] The NSU Delphin III streamliner motorcycle set the motorcycle land speed record in 1956.  Wilhelm Herz rode the machine to 211.4 mph at Bonneville Speedway in Utah, to break 200 mph (320 km/h) for the first time.  Its fairing, designed in a wind tunnel at University of Stuttgart (then Stuttgart Technical College), gave it a drag coefficient of 0.19.  The same engine powered Herz to a 1951 world speed record, with a less efficient frame/fairing, the "Delphin I".  The engine used an unusual rotary supercharger related to NSU's eventual development of the Wankel engine.  In the supercharger, both a trochoidal inner rotor and epitrochoidal outer rotor spun around a stationary shaft.
