Abstract
Methods and systems are provided for flowing crankcase gases through an aspirator arranged in a PCV line. The aspirator regulates PCV flow, and may also generate vacuum depending on a position of a pintle extendable across a horizontal passage of the aspirator. When regulating PCV flow and not generating vacuum, the aspirator is fully closed and crankcase gases in the horizontal passage are metered through an orifice in the pintle. When generating vacuum, the aspirator is at least partially opened and PCV flow through the horizontal passage generates vacuum at a vacuum port of the aspirator.
