Claim 0:
1. An exhaust gas turbocharger for an internal combustion engine, the exhaust gas turbocharger comprising:
a compressor;
a turbine coaxially coupled to the compressor along a turbocharger axis, the turbine including a turbine housing and a turbine wheel rotatably arranged in the turbine housing, the turbine housing comprising:
an exhaust gas supply port configured to receive an exhaust gas mass flow,
an exhaust gas discharge port extending coaxially downstream of the turbine wheel along the turbocharger axis, and
a hollow exhaust gas ring duct configured to convey the exhaust gas mass flow from the exhaust gas supply port to the turbine wheel, the exhaust gas ring duct arranged so as to concentrically encompass the turbine wheel and the exhaust gas discharge port; and

a hollow catalyst substrate block integrated into the turbine housing so as to fill the xaust gas ring duct upstream of the turbine wheel and downstream of the exhaust gas supply port.
