BOOST PURGE EJECTOR TEE ARRANGEMENT

摘要

A boost purge ejector tee arrangement for a fuel vapor emissions system can include a boost purge ejector tee having a body that can define a first inlet port, a second inlet port and an outlet port. The first inlet port and the outlet port can be fluidly coupled along a first flow path. The body can define a second flow path from the second inlet port that can intersect the first flow path upstream of the outlet port. A nozzle can be positioned in the first flow path such that an outlet of the nozzle can be proximate the intersection of the second flow path with the first flow path. The boost purge ejector tee can be integrated into an air box that can be associated with an engine such that the outlet port exits into an inside of the air box.

1. A boost purge ejector tee arrangement for a fuel vapor emissions system coupled to an intake manifold of an engine with a forced induction system, comprising:
a boost purge ejector tee having:
a body defining a first inlet port, a second inlet port and an outlet port, the first inlet port and the outlet port being fluidly coupled along a first flow path, the body defining a second flow path from the second inlet port that intersects the first flow path upstream of the outlet port; anda nozzle positioned in the first flow path such that an outlet of the nozzle is proximate the intersection of the second flow path with the first flow path; wherein the boost purge ejector tee is integrated into an air box associated with the engine such that the outlet port exits into an inside of the air box.
