This patent describes an intake system for a rotary piston engine having engine sections each having a rotor therein and in each of which a working chamber is formed. The engine sections being separated by an intermediate housing and each engine section having at least one intake port for introducing intake air into each of the working chambers. Each of the intake ports communicating with an intake passage means and being located so as to be opened by the respective rotor after a top dead center position of the rotor and closed after a bottom dead center position of the rotor. The respective rotors having a phase difference therebetween. The system comprising communicating passage means for communicating the engine sections so that intake air can be transferred between the engine sections in accordance with the difference in rotor phase between the engine sections, the communicating passage means having openings in the respective sections. The openings being located in the respective sections so as to be opened by the respective rotor a predetermined time after the respective intake port is opened and so as to be closed a predetermined time after the intake port is closed and so as to retain a larger amount of intake air in each of the working chambers than the minimum amount of intake air required for ensuring idling rotation speed under an idling engine operating condition when the communicating passage means is closed.
