Abstract:
Embodiments for vacuum generation are provided. In one example, a method for an engine including a turbocharger having a compressor driven by a turbine comprises generating vacuum via exhaust flow through an ejector, and applying vacuum from the ejector to a wastegate actuator. In this way, vacuum produced via high-pressure exhaust resulting from boosted engine operation may be used to actuate the wastegate valve.
