摘要: An air intake passage leads to a combustion chamber. A throttle valve is disposed in the air intake passage. A first gas passage connects a crank chamber to a point of the air intake passage downstream of the throttle valve. A control valve is disposed in the first gas passage. A second gas passage connects the crank chamber to a point of the air intake passage upstream of the throttle valve. A communication passage connects the second gas passage to a point of the first gas passage between the control valve and the crank chamber.
