What is Wankel (Rotary) Engine?

 Wankel engine, known by the surname of Felix Wankel, who lived between 1902-1988, is an internal combustion engine, has an eccentric rotary design and converts combustion pressure into rotary motion. Unlike other types of internal combustion engines, the Wankel engine uses a triangular rotary piston with splayed edges. All parts of the engine rotate in the same direction. This engine has a smooth movement, compactness and an advanced power-to-weight ratio compared to other engines.

Wankel engines have a simpler structure than normal engines. The engine has a rotating piston inside the oval body. However, this may vary according to the design, and there may be 2, 3 or 4 rotating pistons. Wankel engines are used in the following vehicles. Mazda RX-2 (1971-1974) Mazda RX-3 (1972-1977) Mazda RX-5 (1975-1981) Mazda RX-7 (1978-2002) Mazda RX-8 (2003-2012) Citroen GS Birotor (1974-1977) Audi 100 C2 (1976-1977) Wankel engines, also known as Rotary, used especially in the Mazda RX-8 today, are known for burning oil as part of their design. There are oil nozzles in the intake manifold of the vehicle. In addition, there are injectors for spraying the oil directly into the combustion chamber. As a disadvantage, this requires regular checks to properly lubricate the rotor, and it is necessary to ensure that the oil level is always appropriate.
