Abstract
An exhaust gas turbocharger with an integrated catalyst substrate block and a hybrid vehicle having such a turbocharger are described. The exhaust gas turbocharger has a turbine housing, a turbine wheel and upstream ahead of the turbine wheel a hollow body-shaped catalyst substrate block, which is integrated in the exhaust gas ring duct of the turbine housing of the exhaust gas turbocharger. As a result of the upstream disposal of the turbine wheel and the integration in the exhaust gas ring duct of the turbine housing, particularly good emission values of an associated internal combustion engine can be achieved with a compact construction mode.
Claims7
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.
