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