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]
Mazda Wankel engine. 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, a German engineer. Over the years, displacement has been increased and turbocharging has been added. Mazda rotary engines have a reputation for being relatively small ...
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. In November 1970, GM paid $50 million, ($392,287,918 in 2023 dollars [ 1] ), for initial licenses to produce their version of the Wankel rotary ...
Mazda has created three families of in-house V6 engines. As of 2000, they build and use the Ford Duratec V6 design. J engine – 2.0 L–3.0 L 60° V6 (–1995) K engine – 1.8 L–2.5 L 60° V6. Diesel V6 – 4.1 L–5.5 L ZB/ZC V6. AJ/MZI – 2.5 L and 3.0 L V6 - The Mazda version of the Ford Duratec DOHC V6. The 3.5 L MZI is the Ford ...
Mazda RX-8. The Mazda RX-8 is a sports car manufactured by Japanese automobile manufacturer Mazda between 2003 and 2012. It was first shown in 2001 at the North American International Auto Show. It is the direct successor to the RX-7. [4] Like its predecessors in the RX range, it is powered by a rotary Wankel engine.
The NSU Spider is the first series production car powered by a Wankel rotary engine. In the Spider, a KKM 502 single-rotor engine with a single spark plug was used; it displaces 996 cubic centimetres (61 in 3) from a generating radius of 100 mm, a width of 67 mm, an eccentricity of 14 mm and an equidistant of 2 mm. Compression is 8.5, and the ...
This is geometrically an inverted Wankel engine that operates on the high-efficiency hybrid cycle. [1] [2] In the Wankel, the only successful pistonless rotary engine to date, a figure-eight-like epitrochoid housing surrounds a curved sided triangular rotor. The rotor revolves around a fixed gear in a hula-hoop motion. The output shaft revolves ...
On 19 January 1960 the rotary engine was presented for the first time to specialists and the press in a meeting of the German Engineers' Union at the Deutsches Museum in Munich. In the same year, with the KKM 250, the first practically applied rotary engine was presented in a converted NSU Prinz automobile. At around this time the term "Wankel ...
