ABSTRACT:
A two rotor type rotary piston engine includes an intake system comprised of individual light load intake ports and heavy load intake ports provided in at least one of the intermediate and side housings to open to the respective rotor cavities and adapted to be cyclically closed by the rotors as the rotor rotate, an intake passage including a throttle valve and individual light load and heavy load passages leading respectively to the light load and heavy load intake ports. The light load passages are communicated with each other by a communicating passage downstream of the throttle valve and the heavy load passages are also communicated each other by a further communication passage. The intake port timings and the passage lengths are so determined that pressure resonance effects can be obtained at both medium and high speed engine operations.
