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 Mazda Wankel engines are a family of Wankel rotary combustion car engines produced by Mazda. [7] Wankel engines were invented in 1950s by Felix Wankel, ...
Although Mazda is well known for their Wankel "rotary" engines, the company has been manufacturing piston engines since the earliest years of the Toyo Kogyo company. Early on, they produced overhead camshaft, aluminum blocks, and an innovative block containing both the engine and transmission in one unit.
A General Motors rotary engine at the Ypsilanti Automotive Heritage Museum. 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.
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 ...
Consider also – the Wankel engine, NSU’s baby. (Dr. Felix Wankel started consulting to NSU, at that time the world’s largest maker of motorcycles, in 1951.) Prone to burning its rotor tip ...
Wankel engines (sometimes called 'rotary engines') can be classified based on the number of rotors present. Most production Wankel engines have two rotors, however engines with one, three and four rotors have also been produced. [4] [5] Wankel engines can also be classified based on whether they are naturally aspirated or turbocharged.
In the context of the developed Wankel engine, "rotary" is something of a misnomer. The Wankel principle applied only to a "rotary piston" and not to the engine as a whole which was a stationary assembly, unlike rotary engines employed in WW1 aircraft in which the entire engine rotated about a fixed crankshaft.
