Abstract: An energy recovery system and method is provided for the compressor stage of a turbocharger during surge avoidance operation. The compressor stage includes a housing defining an inlet, an inlet chamber, a diffuser and a volute. A flow amplifier is provided in the compressor housing or in a separate element. If the compressor stage is operating near a surge condition, charge air from a system charge air source is routed to the flow amplifier which discharges the air substantially along the inner peripheral surface of the inlet chamber in a downstream direction relative to the air intake flow direction. The charge air is supplied in a substantially annular manner at an increased velocity such that at least a portion of the intake air flow is entrained by the charge air so as to increase the velocity of the air toward the compressor wheel and recovering energy of the charge air.

Abstract: A rotary wastegate valve (48) includes a valve seat (50) having an opening (58), a valve shaft (80) that extends in a direction normal to a surface of the valve seat (50) and is offset relative a valve plate centroid (C), and a valve plate (90) driven by the valve shaft (80) to rotate relative to the valve seat (50). Rotation of the valve shaft (80) moves the valve plate (390) between a first position in which the valve plate (390) overlies the opening (58) and closes the opening (58), and a second position in which the opening (58) is at least partially open. The rotary wastegate valve (48) can be used to control exhaust gas flow through the turbine section (20) of an exhaust gas turbocharger (1).

Abstract: In an aluminum turbocharger bearing housing, there is a potential for wear of the bearing housing at the interface with the journal bearing system. With a protective hard anodized surface, the wear resistance and resistance to chemical attack of the bearing housing can be improved so that an aluminum bearing housing can have the life of a cast iron bearing housing, at greatly reduced weight.
