Abstract

An exhaust gas-treating device (1) for an exhaust system of an internal combustion engine, especially of a motor vehicle, which is provided with an insert (3), which has a plurality of ducts (5, 5′), through which parallel flow is possible. The insert has, in an inflow-side, first section (6), an oxidation catalyst coating, which forms an oxidation catalytic converter (K1). The insert comprises on an outflow-side a second section (7) with a particle filter (K3) with inlet ducts (12) closed on the outflow side and with outflow ducts (13) closed on the inflow side after the first section (6). Greater integration of a plurality of catalyst components of the exhaust gas-treating device (1) is possible.
