System for improving engine crankcase ventilation via a conduit

摘要

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 in a conduit external to an engine.

主权项

1. A method for improving engine crankcase ventilation, comprising:
providing a flow from a crankcase of an engine to an intake system of the engine via a conduit external from the engine; during a condition when a lateral force or a centripetal force acting on the engine is greater than a threshold amount, limiting flow from the crankcase to the intake system via the conduit; and draining liquids from the conduit to the crankcase when the lateral force or centripetal force is less than the threshold amount.
