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
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.
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 ...
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.
ARV Super2 with AE110. Very closely based upon the Norton engine, the MidWest engine developed the design further. The lubrication system became a semi-total-loss system whereby Silkolene 2-stroke oil was directly injected into the inlet tracts and onto the main roller bearings, but the oil that fed the bearings became an oil-mist within the rotor-cooling air, with about 30% [4] of the oil ...
Making a Wankel engine that can burn Diesel engine fuel, but which does not use the Diesel principle, can be useful if Diesel engine fuel is less expensive than petrol. [5] In a 1974 study conducted for the EPA, it was attempted to determine whether or not a Wankel Diesel engine has a better exhaust behaviour than a regular Otto cycle petrol ...
