Abstract
In a supercharged engine, a supercharger and a throttle body disposed midway in an intake passage are located away from an engine block. A blow-by gas passage constituting a PCV apparatus is connected between a portion of the intake passage located on the upstream side of a throttle valve and a crankcase. The blow-by gas passage returns the blow-by gas collected in the crankcase to the intake passage. A cooling water passage extending from the engine block is connected to a radiator. A water passage extending from the radiator is connected to the engine block via the throttle body, which water passage encloses the blow-by gas passage in an intermediate portion thereof.
