摘要： A rotary engine wherein a side port is formed in one side housing, and a main peripheral port, communicating with the side port, and a bypass peripheral port, communicating with a bypass passage formed in another side housing, are formed in a rotor housing, the side port being maintained in communication with the carburetor through a passage formed in the rotor, while the bypass peripheral port communicates with the carburetor by bypassing the passage in the rotor. Respective valves are mounted in the main peripheral port and the bypass peripheral port, and the two valves are closed or throttled at low engine speeds. The bypass peripheral port opens at higher engine speeds than the main peripheral port.
