Abstract

See full text

The high pressure compressor wheel of a two stage turbocharger assembly is cooled by charge air bled from the charge air flowpath downstream of the aftercooler. A wastegate may be arranged across the high pressure stage and operated by an actuator which in turn is operable by the static or dynamic pressure of the charge air in the cooling flowpath. The cooling airflow may be blocked to open the wastegate and released or resumed to close the wastegate so that cooling air is supplied only while the high pressure compressor wheel is under load.
