This is a rotary internal combustion engine perfected by Felix Wankel during the 1950s and 60s. This engine has two-thirds less moving parts than the traditional piston-powered engine used in all diesel and gasoline engines sold in America. Oddly enough, power is derived from an almost triangle-shaped rotor spinning within an almost oval housing. The advantages are very smooth operation, more reliability than a standard piston engine and greater ability to utilize multiple fuels in the future.
