As an effect of this, the Wankel engine has slow and incomplete combustion, which results in high fuel consumption and bad exhaust gas behavior. [122] Wankel engines can reach a typical maximum efficiency of about 30 percent. [125] In a Wankel rotary engine, fuel combustion is slow, because the combustion chamber is long, thin, and moving.
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.
The engine configuration describes the fundamental operating principles by which internal combustion engines are categorized. Piston engines are often categorized by their cylinder layout, valves and camshafts. Wankel engines are often categorized by the number of rotors present. Gas turbine engines are often categorized into turbojets ...

The Mercedes-Benz M 950 is a prototype Wankel rotary engine made by Daimler-Benz. It was first described in Wolf-Dieter Bensinger's 1969 essay Der heutige Entwicklungsstand des Wankelmotors, published in January of 1970. [1] The engine was developed by Daimler-Benz's Wankel engine department, headed by Bensinger.
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 ...
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 ...
Rotary engines of the Wankel design are used in some automobiles, aircraft and motorcycles. These are collectively known as internal-combustion-engine vehicles (ICEV). [18] Where high power-to-weight ratios are required, internal combustion engines appear in the form of combustion turbines, or sometimes Wankel engines.
