摘要:
A boost purge ejector tee arrangement is integrated into a turbocompressor associated with an engine and includes first and second passages, an inlet port and a nozzle. The first passage is formed into a housing of the turbocompressor and includes an outlet in communication with a turbocompressor inlet. The second passage is formed into the housing and includes a boost air inlet in communication with an internal outlet area of the turbocompressor and intersecting the first passage. The inlet port is associated with the housing and intersects the first passage. The nozzle is positioned in the first passage such that an outlet of the nozzle is proximate the intersection of the inlet port and first passage. During a boost mode of operation, the second passage is adapted to receive boost air flow, which flows through the nozzle thereby creating a vacuum and drawing purge through the inlet port.
