    摘要: A selectively operable vacuum source is disclosed. In one example, vacuum source supplies as much air to an engine as is drawn by the vacuum source from a vacuum reservoir. The approach may provide vacuum to a vehicle vacuum system efficiently and with less weight than other vacuum sources.

    摘要: Systems and methods for generating a vacuum in an engine are provided. The system includes a first throttle upstream from a plurality of cylinders and a second throttle upstream from one of the cylinders. The system further includes a vacuum reservoir in fluidic communication with an intake runner downstream from the second throttle; a vacuum consumer in fluidic communication with the vacuum reservoir, the vacuum consumer controlled by an actuator; and a pneumatic actuator driven by a pressure state of the vacuum reservoir to adjust the second throttle.
