摘要：
Methods and systems are provided for generating vacuum from crankcase ventilation flow. During both directions of gas flow between an engine intake manifold and a crankcase, gases are directed through one or more aspirators to produce vacuum. The drawn vacuum may then be used to operate various engine vacuum actuators.
