Vankel+engine

The Wankel engine is a type of a petrol fuel engine which uses a rotary design to convert pressure into a rotating motion instead of using normal pistons. Its four-stroke cycle takes place in a space between the inside of an oval-like cylinder and a rotor that is similar in shape to a Reuleaux triangle but with sides that are a little flatter. This design delivers smooth high- rpm power from a compact size. Since its introduction the engine has been referred to be called as the rotary engine. Like an ordinary four-stroke engine has the Wankel engine four phases: intake, compression, job type and exhaust. All three sides of the piston goes through these four phases during a lap, however displaced relative to each other. The engine was invented by the German engineer Felix Wankel. He began to build in the early 1950s at NSU Motorenwerke AG before he completed a working, running prototype in 1957. NSU then licensed the concept to companies around the world, who have continued to improve the design.

Because of their compact design, Wankel rotary engines have been installed in a variety of vehicles and devices such as automobiles including racing cars, also with aircraft , go-karts , personal water craft , chain saws , and auxiliary power units. The Japanese car brand Mazda is the one that uses the Wankel engine the most, especially in their car models Rx7 and Rx8.
