Wankel rotary engine was conceived in 1924 and received his patent in 1929. During the 1940s he devoted himself to improving the design. It made a considerable effort in developing rotary engines in 1950 and 1960. Were particularly interesting to work in a smooth, quiet and reliable, thanks to the simplicity of its design.
A rotary or Wankel engine, in honor of its creator Dr. Felix Wankel is an internal combustion engine that works in a way completely different from conventional engines.
In an alternative engine, the same volume (cylinder) successively performs 4 different jobs - admission, compression, combustion and exhaust. In a Wankel engine developed the same time but in 4 different places of the frame or block, ie, it's like having a dedicated cylinder each time, with the piston moving continually from one to another. More specifically, the cylinder-shaped cavity 8, which is located within a triangular piston performs a variable center of rotation. This piston communicates its motion to a rotating crankshaft that is inside, and that it rotates with a center unique.
