Abstract: A compressor for a turbocharger is supplied with crank case ventilation (CCV) gases from the engine which is turbocharged. The CCV gases are piped into an inlet of the compressor housing which supports an insert with an MWE structure. The MWE structure comprises an outer wall and an inner wall with a gas flow passage defined between them.

The CCV gases are directed to a position upstream of an inlet to the gas flow passage where they emerge through an outlet which may be defined in the insert. The CCV gases may be supplied to the outlet via a chamber defined between the insert and the compressor housing. The arrangement provides for improved mixing of CCV gases with the incoming air and does not compromise noise reduction.
