Abstract: A compressor arrangement for a turbocharger is disclosed. The compressor arrangement comprises a compressor housing and a compressor wheel arranged to rotate in the compressor housing. The compressor housing comprises a compressor inlet duct, a ported shroud, and a recirculation channel comprising an inlet arranged downstream of the compressor wheel, an outlet arranged in the compressor inlet duct at a position upstream of ports of the ported shroud, and a valve configured to control the flow of air through the recirculation channel. The compressor arrangement further comprises a wall section protruding into the compressor inlet duct at a position upstream of the outlet of the recirculation channel. The present disclosure further relates to a turbocharger, an internal combustion engine, and a vehicle.

Abstract: Disclosed is a turbocharger for an internal combustion engine comprising a turbine having a turbine housing and a diffusor. The turbine housing comprises an exhaust gas outlet volume, and the diffusor is arranged in this volume. A housing orifice and a diffusor orifice are arranged through each of the turbine housing and diffusor respectively and are mutually aligned to provide an opening into the exhaust gas outlet volume. The turbocharger further comprises a bushing arranged within the housing orifice and extending towards the diffusor orifice and ending at a first end in association with the diffusor orifice. The first end of bushing has an internal diameter that is greater than or equal to a diameter of the diffusor orifice.
