ABSTRACT:
A two rotor type rotary piston engine including a casing comprised of a pair of rotor housings connected together with an intermediate housing interposed therebetween and side housings attached to the outer sides of the rotor housings to define rotor cavities. A substantially triangular rotor is disposed in each rotor cavity. The intake system includes a light load intake port formed in the intermediate housing so as to open to each rotor cavity, a medium load and heavy load intake ports formed in each side housing. The light load and medium load intake ports are formed so that they are opened to a working chamber after the chamber is disconnected from the exhaust port and closed substantially simultaneously. The heavy load intake port is associated with a control valve which is closed under light and medium load operations.
