摘要

The exhaust gas system (1) has a swirl device (12), which is arranged in an exhaust gas pipe section (11) and a catalyst (18) is arranged in another exhaust gas pipe section (17), where third exhaust gas pipe section (14) is provided between the swirl device and the catalyst. A dosing device (10) for a reducing agent, particularly an aqueous urea solution, is arranged in an upstream region of the swirl device. The catalyst is a silicon controlled rectifier-catalyst.
