Wankel engine

Wan·kel engine

W0025400 (väng′kəl, wäng′-, wăng′-)n. 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

(ˈwæŋkəl) n (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]

(ˈwɑŋ kəl, ˈwæŋ-)
n. an internal-combustion rotary engine with a triangular rotor that revolves in a chamber. [after Felix Wankel (1902–88), German engineer, its inventor]

Wankel Engine

a rotary-piston internal-combustion engine whose design was developed in 1957 by F. Wankel (Federal Republic of Germany), an engineer. A special feature of the engine is the use of a turning rotor (piston) mounted in a casing whose surface has the shape of an epitrochoid. The shaft-mounted rotor is rigidly joined to a gear that meshes with a stationary pinion. The rotor and gear rotate around the piston. During rotation the rotor apexes slide along the epitrochoidal surface of the casing and cut off the variable volumes of the chambers in the casing. Such a design makes it possible to achieve a four-stroke cycle without the use of a special gas distribution device. Sealing of the chambers is provided by radial and face sealing vanes, which are pressed to the cylinder by centrifugal force, gas pressure, and band springs. Carburetion, ignition, lubrication, cooling, and starting are basically similar to the ordinary piston-type internal-combustion engine.

Trihedral-rotor engines with a pinion and gear radius ratio of r:R = 2:3 have found practical application in automobiles, boats, and so on.

The weight and dimensions of the Wankel engine are two to three times less than a corresponding conventional internal-combustion engine system with equivalent horsepower. Wankel engines are being manufactured in the Federal Republic of Germany, Japan, and the USA.

Wankel engine

[′väŋ·kəl ‚en·jən] (mechanical engineering) An eccentric-rotor-type internal combustion engine with only two primary moving parts, the rotor and the eccentric shaft; the rotor moves in one direction around the trochoidal chamber containing peripheral intake and exhaust ports. Also known as rotary-combustion engine.
