Ejector system for a vehicle

摘要

A selectively operable vacuum source designed to reduce leakage is disclosed. In one example, the vacuum source is at least partially within an engine air intake system. The approach may reduce a number of sensors required to diagnose whether or not leaks are present within the vacuum source.

1. A system for a vehicle, comprising:
an engine including an intake passage housing a compressor; and a vacuum generating device including a motive fluid inlet section extending from upstream of the compressor to downstream of the compressor, a value positioned along a length of the motive fluid inlet section, a diverging discharge section positioned within the intake passage upstream of an inlet of the compressor, and a suction inlet pneumatically communicating with a vacuum reservoir.
