ABSTRACT:
Rotary piston engine having a main intake port in one side housing of the casing. The side housing is further formed with a supercharging air port which is connected with a supercharging passage leading from an air pump. The supercharging air port is so formed that it is opened substantially simultaneously with and closed later than the main intake port. A timing valve is provided in the supercharging passage to open the passage cyclically so that the supercharging is performed at the end period of the intake stroke. A centrifugal device controls the valve timing so that the valve timing is advanced under an increased engine speed.
