Abstract
An engine including: an exhaust manifold provided near one side surface of an engine; a turbocharger having an exhaust-side inlet connected to the exhaust manifold; and a rocker-arm-chamber-integrated intake manifold disposed on a cylinder head and integrally including a rocker arm chamber and an intake manifold. The intake manifold has a wall dividing the rocker arm chamber provided near one side surface of the engine and the intake manifold provided near another side surface thereof to isolate the rocker arm chamber and the intake manifold from each other. The rocker arm chamber has, in its upper portion, a positive crankcase ventilation device protruding therefrom and returning blowby gas to an intake system. The positive crankcase ventilation device has a blowby-gas discharge port connected with a gas conduit through which blowby gas is delivered to an intake-side inlet of the turbocharger.
