Abstract
A turbine housing assembly for use in a turbocharger having an exhaust gas driven turbine wheel for rotatably driving a compressor impeller. The assembly includes a turbine housing having an exducer passage into which exhaust gases are discharged from the turbine wheel. A bypass passage in the turbine housing and a pivoting wastegate valve cooperate to provide an efficient exhaust ejector for drawing gases through the exducer passage to reduce back-pressure on the engine. The turbine housing further includes an air vent for circulation of cooling air between the bypass and exducer passages.
