ABSTRACT:
A rotary piston engine including a casing comprised of a rotor housing and a pair of side housings attached to the opposite sides of the rotor housing to define a rotor cavity. A substantially triangular rotor is disposed in the rotor cavity. The intake system includes a light load intake port formed in one of the side housings so as to open to the rotor cavity, a medium load and heavy load intake ports formed in the other side housing. The light load and medium load intake ports are formed so that they are opened to a working chamber before the chamber is disconnected from the exhaust port. The heavy load intake port is associated with a control valve which is closed under light and medium load operations. The medium load intake port has an effective area smaller than that of the light load intake port and is closed earlier than the light load intake port.
