Method and system for fuel vapor management
Abstract:
Methods and systems are provided for ventilating a crankcase in an engine. In one example, when the engine is operating boosted under cruising conditions, fuel vapors from the crankcase may flow to each of a compressor inlet and an intake manifold of the engine. In this way, the crankcase may be effectively purged.
