Abstract

An intake passage (20) has an upstream portion (20a) in an upstream side of a supercharger (24), an intermediate portion (20b) between a supercharger (24) and a throttle valve (30), and a downstream portion (20c) in a downstream side of the throttle valve (30). A first breather passage (41) connects an interior of an engine (10) with the downstream portion (20c). A second breather passage (42) connects the interior of the engine (10) with the upstream portion (20a). Introduction passages (43, 44) communicate the upstream portion (20a) with the interior of the engine (10) at a non- supercharging time, and connect at least one of the intermediate portion (20b) and the downstream portion (20c) with the interior of the engine (10) at a supercharging time. Thus, the interior of the engine is efficiently ventilated.
