Abstract

An exhaust gas turbocharger (1) including a compressor housing (2), a bearing housing (3), a turbine housing (4) in which a turbine wheel (5) is arranged, which has a housing inlet (6), which has a turbine spiral (7) connecting to the housing inlet (6), which has a housing outlet (8), and which has a wastegate arrangement (9), which in the open state brings the housing inlet (6) into flow connection with the housing outlet (8) for guiding a wastegate mass flow. The wastegate insert part (10) is arranged in the turbine housing (4) between the turbine wheel (5) and the housing outlet (8) and the open wastegate arrangement (9) introduces the wastegate mass flow into the wastegate insert arrangement (9).
