Abstract
A rotary internal combustion engine composed of three identical rotors and a main shaft going through the centers of the three rotors. The first rotor is used for compressing a fuel/air mixture, the second rotor is used for creating power and the third rotor is used to compress fresh air. The rotating sequence of the three rotors is as follows: the first rotor compresses the fuel/air mixture into the second rotor, which then ignites the fuel/air mixture to create power. The third rotor compresses fresh air and supplies same to the second rotor to assist in the burning of the fuel/air mixture. Therefore, a second burning device is provided to more thoroughly burn the gas and exhaust relatively clean waste gas.
