Abstract
An intake passage has an upstream portion in an upstream side of a supercharger, an intermediate portion between a supercharger and a throttle valve, and a downstream portion in a downstream side of the throttle valve. A first breather passage connects an interior of an engine with the downstream portion. A second breather passage connects the interior of the engine with the upstream portion. Introduction passages communicate the upstream portion with the interior of the engine at a non-supercharging time, and connect at least one of the intermediate portion and the downstream portion with the interior of the engine at a supercharging time. Thus, the interior of the engine is efficiently ventilated.
