ABSTRACT:
An intake system for three-rotor type rotary piston engine having first, second and third engine sections, and three rotors, the rotors being in 120-degree phase difference in terms of eccentric shaft rotation, a first communicating passage for communicating the working chamber in which the compression stroke is proceeding in the first engine section and the working chamber in which the intake stroke is proceeding in the second engine section, a second communicating passage for communicating the working chamber in which the compression stroke is proceeding in the second engine section and the working chamber in which the intake stroke is proceeding in the third engine section, and a third communicating passage for communicating the working chamber in which the compression stroke is proceeding in the third engine section and the working chamber in which the intake stroke is proceeding in the third engine section, each communicating passage being provided with a valve for controlling the openings thereof in accordance with the engine load. According to the present invention, there can be obtained an intake system for three-rotor type rotary piston engine capable of uniformly reducing the pumping loss in each engine section and drawing the same amount of intake air from the intake port to each engine section.
