Abstract:
An exhaust gas treatment system (10) for treating exhaust gases (12) of an internal combustion engine of a motor vehicle has an exhaust gas catalytic converter, a pipe piece (14) connected to an input side of the exhaust gas catalytic converter for feeding in exhaust gases (12) of the internal combustion engine, and a heating line (20) that opens into the pipe piece (14) for feeding heating gas (16) into the pipe piece (14) for heating the exhaust gas catalytic converter to the light-off temperature. The heating gas (16) is fed in as a vortex flow that rotates about a longitudinal axis of the pipe piece (14) to achieve homogeneous thorough mixing with the exhaust gas (12) with rapid heating across an entire cross-section of the exhaust gas catalytic converter.
