    摘要: 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.

    摘要: An engine with a positive pressure assisted brake booster is disclosed. In one example, an operator applying vehicle brakes is assisted by positive pressure provided by a compressor coupled to an engine of the vehicle. Operation of the vehicle brakes may be improved especially when engine vacuum is limited.

    摘要: A method and system for controlling a fuel pressurizing system in a direct-injection, spark-ignition engine is disclosed such that the ticking sound of a solenoid valve in the high pressure pump is disabled at certain engine operating conditions. The fuel pressurizing system includes two pumps in series: a low pressure lift pump and a high pressure pump. Based on an engine operating parameter (speed, load, temperature, fuel delivery rate, as examples) the high pressure fuel pump is disabled when the engine operating parameter is below a threshold. The disablement of the pump is accomplished by turning off the normally-open solenoid valve on the inlet side of the high pressure pump, particularly at low speed and/or low torque conditions, e.g., idle, when the ticking of the injector is particularly noticeable. When the pump is disabled, fuel is supplied to the fuel injectors at lift pump pressure.
