An internal combustion engine for an automotive vehicle has an intake manifold receiving fresh air via an inlet duct. The engine includes a crankcase. A turbocharger is provided having a compressor with an inlet coupled to the inlet duct and an outlet coupled to the intake manifold. A first vent line couples the crankcase with the compressor inlet. A second vent line couples the crankcase with the compressor outlet and intake manifold. The second vent line has a valve blocking air flow into the crankcase and allowing air flow out from the crankcase. The first vent line comprises a dual-acting valve having a first flow capacity into the crankcase and a second flow capacity out from the crankcase which is greater than the first flow capacity. Thus, crankcase ventilation is optimized for both engine idle and high engine load conditions.

Crankcase ventilation for turbocharged engine

A high pressure charge air feed arrangement for an internal combustion engine is provided. The arrangement includes an intake having a high pressure output, a rocker cover having an intake runner defining a high pressure charge flow path, and a gas and oil separator having a flow accelerator with input and output sides. The high pressure output of the intake is attached to one end of the path and the accelerator is attached to the other end. The path is connected between the input and output sides of the accelerator. The separator includes upper and lower plenums divided by a wall having an oil and gas diffuser. The input side is connected to the lower plenum and the output side is connected to a crankcase oil return line. The flow accelerator may be any type of fluid accelerator, including, but not limited to, a venturi pump and a jet pump.

A system for improving PCV flow of an engine is presented. The system can reduce engine oil consumption when an engine is exposed to lateral or centripetal force. In one example, the system includes a mechanically operated valve that acts to limit PCV flow.
