Wan·kel engine

 (väng′kəl, wäng′-, wăng′-)
A rotary internal-combustion engine in which a triangular rotor turning in a specially shaped housing performs the functions allotted to the pistons of a conventional engine, thereby allowing great savings in weight and moving parts.

[After Felix Wankel (1902-1988), German engineer.]

Wankel engine

(Automotive Engineering) a type of four-stroke internal-combustion engine without reciprocating parts. It consists of one or more approximately elliptical combustion chambers within which a curved triangular-shaped piston rotates, by the explosion of compressed gas, dividing the combustion chamber into three gastight sections
[C20: named after Felix Wankel (1902–88), German engineer who invented it]

The 110S made its entry into the sports-car segment and was the first-ever production car to be powered by a twin-rotor Wankel engine.
Wankel engine offers some advantages of both the turbine cycle and the flexibility of the reciprocating engine [9, 10].
It is also possible to directly measure heat flux to the combustion chamber walls, but this technique requires the adoption of complex, expensive, and intrusive sensors [11], which in some cases cannot be easily used, for example, to measure the heat flux on moving parts such as a piston or the rotor of a Wankel engine [12].
Besides the four expanders discussed here, there are some other types of expanders have been considered during the RC application to vehicles, such as Vane-cell expander [37], Wankel engine [45, 46], etc., which are not discussed in the current work.
"The reason we ultimately chose Rotron is because of their great technological capabilities and innovativeness, and because their Wankel engine meets our requirements and specifications in full," says Rolf Schytt, CybAero's chief operating officer.
Indeed, the single-rotor Wankel engine that the British engineering firm has now developed not only delivers over 1hp for every pound it weighs, but it also has the unique ability to start and run on both kerosene-based JP8/Jet-A1 and petrol at temperatures as low as -32degC.
A Wankel engine is a type of internal combustion engine which works using the piston rotary movement (Fig.
