Motor de combustao interna de pistoes rotativos triangulares curvilineos: Wankel

The internal combustion engine the and rotary combustion piston curvilinear triangular, revolving troncoidais cavities was developed by German engineer Felix Wankel. This engine works on the four traditional Otto cycle times. The automaker Mazda was the company that used the Wankel engine in his sports car RX-7 and RX-8. In the past several empresam built cars with Wankel engines, such as NSU and Citroen while Mercedes-Benz and GM made vehicle prototype with this technology. Some motorcycle builders like Norton, DKW Hercules and Suzuki used the Wankel technology. Currently this technology is also applied in aircraft and "hovercrafts" for its low weight. Currently the use of Wankel engines is very restricted in the automotive industry, as these companies are afraid to invest in this technology due to technological advances of the main competitor of Wankel engines known as Quasiturbine engine that is the big bet of the future.
