ABSTRACT:
A rotary piston engine having three or more rotors and provided with an intake system including a primary individual intake passage leading to each rotor unit and a secondary individual intake passage leading to each rotor unit for providing a supply of intake charge under a heavy load engine operation. The secondary individual intake passages are connected together by a junction and have passage lengths which are determined such that the pressure wave produced at the intake port for one rotor unit is transmitted to the intake port for another rotor unit after a time interval corresponding to 180.degree. in terms of angle of rotation of the eccentric shaft.
