Abstract
Methods and systems are provided for a self-disabling ejector of an air induction system and evaporative emissions systems. In one example, an ejector may include an outlet coupled to an inlet flow port of an air induction passage, upstream of a compressor, an evacuation port coupled to an external protrusion arranged adjacent to the inlet flow port on the air induction passage, a constriction arranged between the outlet and evacuation port, and first and second inlets positioned on either side of the constriction. If the outlet becomes disconnected from the inlet flow port, the evacuation port may disconnect from the external protrusion, thereby disabling the vacuum generating capabilities of the ejector.
