Abstract
A blowby gas returning apparatus is mounted in an engine provided with a turbocharger in an intake passage and provided with a blowby gas returning passage for flowing blowby gas generated in the engine to return to the engine. This apparatus comprises an intake bypass passage connecting an upstream side and a downstream side of the intake passage with respect to the turbocharger, and a jet pump for generating negative pressure in the intake bypass passage. An exit of the first blowby gas returning passage is connected to the intake bypass passage through the jet pump. The apparatus further includes a second blowby gas returning passage connecting the intake passage downstream of the throttle valve to a head cover. In the head cover, a PCV valve is placed at an entrance of the second blowby gas returning passage.
