The Wankel engine (/ˈvaŋkəl̩/, VUN-kell) is a type of internal combustion engine using an eccentric rotary design to convert pressure into rotating motion. The concept was proven by German engineer Felix Wankel, followed by a commercially feasible engine designed by German engineer Hanns-Dieter Paschke. [1]
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.
Annual Mazda Wankel "rotary" engine sales 1967–2000, excluding RX-8 and without industry engines (data source: Ward's AutoNews) Mazda was fully committed to the Wankel engine just as the energy crisis of the 1970s struck. The company had all but eliminated piston engines from its products in 1974, a decision that nearly led to the company's ...
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.
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 ...
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.
