Abstract

Methods and systems are provided for controlling air ingestion in an engine during idle conditions. One example approach includes adjusting an opening of a common shut-off valve via an electronic controller, the common shut-off valve regulating each of motive flow through an aspirator and crankcase ventilation (CV) flow from a crankcase. As such, the common shut-off valve may be closed by the electronic controller during engine idle to cease each of the motive flow through the aspirator and the CV flow from the crankcase.
