In 1972, Yamaha introduced the RZ201 at the Tokyo Motor Show, a prototype with a Wankel engine, weighing 220 kg and producing 60 hp (45 kW) from a twin-rotor 660-cc engine (US patent N3964448). In 1972, Kawasaki presented its two-rotor Kawasaki X99 rotary engine prototype (US patents N 3848574 &3991722).
The Germans were very familiar with and respectful of Bentele and he was a great asset to Curtiss-Wright. Unexpectedly, NSU, who held patents and rights to the Wankel-derived engine in many countries, failed to patent their engine in the United States, due to complex patent laws, and to their lawyer who was unfamiliar with these laws.
Felix Heinrich Wankel (German: [ˈfeːlɪks ˈhaɪnʁɪç ˈvaŋkl̩]; 13 August 1902 – 9 October 1988) was a German mechanical engineer and inventor after whom the Wankel engine was named. [ 1 ] Early life
1972 GM Rotary engine cutaway shows twin-rotors. Popular Science magazine in the May 1972 article "GM Rotary Engine for the 1974 Vega", an illustration of the Wankel installed in a 1974 Vega hatchback showed a different grille, a lower, more sloped hood line, and a "GM Rotary" badge and Wankel crest on the rear quarter panel.
In addition to SPARCS, Garside also filed a patent in 2011 to develop a rotary exhaust expander unit or CREEV (compound rotary engine for electric vehicles) for use with Wankel rotary engines. [13] The CREEV system acts as an ‘exhaust reactor’ by consuming unburned exhaust products while expansion occurs, reducing overall emissions and ...
In the 1930s he met Felix Wankel, who became a long-term friend, and with whom Bensinger had a strong bond of trust. [5] From 1943 [6] or 1944 Besinger worked as an engineer with Daimler-Benz AG in Stuttgart [1] where he became head of New Engine Development. From 1945, Bensinger became head of Passenger Car Engine Development. [2]
1929 – Felix Wankel patents the Wankel rotary engine (U.S. patent 2,988,008). [17] Late 1930s – Hans von Ohain [18] and Frank Whittle [19] separately build pioneering gas turbine engines intended for aircraft propulsion, leading to the pioneering turbojet powered flights in 1939 Germany and 1941 England.
The Mercedes-Benz M 950 is a prototype Wankel rotary engine made by Daimler-Benz. It was first described in Wolf-Dieter Bensinger's 1969 essay Der heutige Entwicklungsstand des Wankelmotors, published in January of 1970. [1] The engine was developed by Daimler-Benz's Wankel engine department, headed by Bensinger.
