Abstract: A combustion engine for a motor vehicle includes an exhaust gas tract through which exhaust gas from a combustion chamber of the combustion engine can flow. An exhaust gas turbocharger has a turbine which is arranged in the exhaust gas tract and which has a turbine housing and a turbine wheel at least partially received in the turbine housing and driveable by the exhaust gas. Via a secondary air channel, which opens out into the exhaust gas tract, secondary air flowing through the secondary air channel can be introduced into the exhaust gas flowing through the exhaust gas tract. The secondary air channel opens out inside the turbine housing into the exhaust gas tract.

Abstract: A method for operating an internal combustion engine of a motor vehicle. The internal combustion engine includes a combustion chamber, an intake tract, a compressor disposed in the intake tract, and a conduit element which is fluidly connected to the intake tract. The internal combustion engine is operable in a heating mode to heat at least a compressor housing of the compressor. In the heating mode a part of the air flowing through the intake tract and compressed by the compressor is returned to the intake tract by the conduit element. The method includes recording a temperature of the air in the intake tract upstream of the compressor by a sensor and comparing the temperature with a threshold value. When the temperature is lower than the threshold value, the internal combustion engine is operated in the heating mode.
