Question: The NSU Delphin III streamliner motorcycle set the motorcycle land speed record in what year, the engine used an unusual rotary supercharger related to NSU's eventual development of the Wankel engine is a type of internal combustion engine using an eccentric rotary design to convert pressure into rotating motion?
Context: The General Motors Rotary Combustion Engine (GMRCE) is an internal combustion Wankel engine which uses a rotary design to convert pressure into a rotating motion instead of using reciprocating pistons.  In November 1970, GM paid $50 million for initial licenses to produce their version of the Wankel rotary engine, and GM President Ed Cole initially projected its release in three years.  Chevrolet, with impetus from Pete Estes and John DeLorean, as well as Ed Cole worked on the Wankel.  Bob Templin was the chief executive in charge of rotary-engine research at the GM Tech Center in Warren, Michigan, but Ed Cole would leave his office in Detroit twice a week for the trip to Warren, taking charge of the program.  The engine was initially targeted for an October 1973 introduction as a 1974 Chevrolet Vega option. A pressure wave supercharger (also known as a wave rotor) is a type of supercharger technology that harnesses the pressure waves produced by an internal combustion engine exhaust gas pulses to compress the intake air.  Its automotive use is not widespread; the most widely used example is the "Comprex", developed by Brown Boveri.  Valmet Tractors of Finland were one of the first to use the device when they fitted it to the 411CX engine which powered their 1203 model of 1980.  Although it provided a useful increase in performance it was considered too expensive to be incorporated into later models.  Ferrari tested such a device during the development of the 126C Formula One car.  The system did not lend itself to as tidy an installation as the alternative twin-turbocharger layout, and the car was never raced in this form.  A more successful application was in the RF series diesel engine found in the 1988 Mazda 626 Capella; ultimately 150,000 Mazda diesel cars were fitted with a Comprex supercharger.  Other users included Peugeot and Mercedes-Benz.  The Greenpeace SmILE concept car uses a "Hyprex" pressure wave supercharger developed by the Swiss company Wenko AG.  NASA uses wave rotors in experiments attempting to increase gas turbine efficiency.  The wave rotor is placed between the compressor, combustor, and turbine sections in order to extract more energy from the combustion process. Nikolaus August Otto (14 June 1832, Holzhausen an der Haide, Nassau – 26 January 1891, Cologne) was the German engineer who successfully developed the compressed charge internal combustion engine which ran on petroleum gas and led to the modern internal combustion engine.  The VDI (Association of German Engineers) created DIN standard 1940 which says "Otto Engine: internal combustion engine in which the compressed fuel-air mixture is initiated by a timed spark ignition" which has been applied to all engines of this type since. A hydrogen internal combustion engine vehicle (HICEV) is a type of hydrogen vehicle using an internal combustion engine.  Hydrogen internal combustion engine vehicles are different from hydrogen fuel cell vehicles (which use electrochemical conversion of hydrogen rather than combustion); the hydrogen internal combustion engine is simply a modified version of the traditional gasoline-powered internal combustion engine. 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. The Triumph Infor Rocket Streamliner (previously known as the Hot Rod Conspiracy/Carpenter Racing Castrol Rocket or Triumph Castrol Rocket) is a streamliner motorcycle built to challenge the motorcycle land speed record.  It is powered by twin destroked and turbocharged 1485 cc inline-3 engines sourced from the Triumph Rocket III, generating a claimed output greater than 1000 hp .  The streamliner shell is a monocoque constructed from carbon fiber/kevlar. The Sarich orbital engine is a type of internal combustion engine, invented in 1972 by Ralph Sarich, an engineer from Perth, Australia, which features orbital rather than reciprocating motion of its internal parts.  It differs from the conceptually similar Wankel engine by using a generally prismatic shaped rotor that orbits the axis of the engine, without rotation, rather than the rotating trilobular rotor of the Wankel. A reciprocating engine, also often known as a piston engine, is typically a heat engine (although there are also pneumatic and hydraulic reciprocating engines) that uses one or more reciprocating pistons to convert pressure into a rotating motion.  This article describes the common features of all types.  The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the Industrial Revolution; and the niche application Stirling engine.  Internal combustion engines are further classified in two ways: either a spark-ignition (SI) engine, where the spark plug initiates the combustion; or a compression-ignition (CI) engine, where the air within the cylinder is compressed, thus heating it, so that the heated air ignites fuel that is injected then or earlier. A pistonless rotary engine is an internal combustion engine that does not use pistons in the way a reciprocating engine does, but instead uses one or more rotors, sometimes called rotary pistons.  An example of a pistonless rotary engine is the Wankel engine. 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.
