Engine designers had always been aware of the many limitations of the rotary engine, so when static style engines became more reliable and gave better specific weights and fuel consumption, the days of the rotary engine were numbered. Rotary engines had a fundamentally inefficient total-loss oiling system. In order to reach the whole engine ...
The ramjet engine was designed by French engineer René Leduc. 1957: The first working prototype of the pistonless Wankel engine (sometimes called a rotary engine) is built by German engineer Felix Wankel. 1957: First usage of electronic fuel injection (EFI) in a production passenger car, using the American Bendix Electrojector system.
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. They stated the ...
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]
The Renesis won International Engine of the Year and Best New Engine awards 2003 [26] and also holds the "2.5 to 3 liter" (note that the engine is designated as a 1.3–litre by Mazda) size award [27] for 2003 and 2004, where it is considered a 2.6 L engine, but only for the matter of giving awards.
The first radial-configuration engine known to use a twin-row design was the 160 hp Gnôme "Double Lambda" rotary engine of 1912, designed as a 14-cylinder twin-row version of the firm's 80 hp Lambda single-row seven-cylinder rotary, however reliability and cooling problems limited its success.
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.
Motorenfabrik Oberursel A.G. was a German manufacturer of automobile, locomotive and aircraft engines situated in Oberursel (Taunus), near Frankfurt (Main), Germany.During World War I it supplied a major 100 hp-class rotary engine that was used in a number of early-war fighter aircraft designs.
