Abstract: An engine includes: an exhaust manifold 7 close to one of left and right side surfaces of an engine; a turbocharger 60 having an exhaust-side inlet connected to the exhaust manifold 7; and a rocker-arm-chamber-integrated intake manifold 8 being disposed on an upper surface of a cylinder head 5 and integrally including a rocker arm chamber 90 and an intake manifold 6. The intake manifold 8 has a wall 101 dividing the rocker arm chamber 90 close to the one of the left and right side surfaces of the engine 1 and the intake manifold 6 close to the other of the left and right side surfaces to isolate the rocker arm chamber 90 and the intake manifold 6 from each other. The rocker arm chamber 90 has, in its upper portion, a positive crankcase ventilation device 69 protruding therefrom and being configured to return blowby gas to an intake system. The positive crankcase ventilation device 69 has, in its side surface, a blowby-gas discharge port 67 connected with a gas conduit 68 through which blowby gas is delivered to an intake-side inlet of the turbocharger 60.

Abstract: A lubricating configuration in a two-stroke cycle, opposed-piston engine for a piston wristpin minimizes losses in oil pressure at the wristpin as the piston approaches bottom center and reduces the required oil supply pressure to the engine. The wristpin is constructed to absorb and store oil pressure energy when oil pressure at the wristpin is high, and to release that stored energy to pressurize the oil at the wristpin when connecting rod oil pressure is low.

Abstract: A feed line for connecting an oil pump to a turbocharger supplies oil to the turbocharger when the oil pump is active. The feed line includes a turbo end and a pump end, which is lower than the turbo end relative to gravity. Oil drains from at least the pump end of the feed line when the oil pump is not active. The feed line has a center axis running therethrough, and a pool zone is disposed between the pump end and the turbo end of the feed line. The center axis of the feed line drops from a main line level on either side of the pool zone to a trap level in the pool zone. The pool zone therefore retains oil when the oil pump is not active.

Abstract: An oil control valve assembly for an engine is provided that has a control valve with a valve body, and a manifold that defines a control passage in fluid communication with a valve lift switching component and an exhaust passage for exhausting fluid from the valve. The control valve is controllable to selectively direct fluid from a supply source to the control passage to actuate the valve lift switching component. An elongated tubular member is positioned adjacent the engine component and is operatively connected to the exhaust passage such that fluid flows from the exhaust passage to the elongated tubular member and through the elongated tubular member onto the engine component.
