Patent ID: 8454897

Claim:
An exhaust gas-treating device for an exhaust system of an internal combustion engine, the exhaust gas-treating device comprising: a particle filter; an oxidation catalytic converter arranged upstream of the particle filter with respect to a direction of an exhaust gas flow; and an insert with a plurality of ducts for parallel flow therethrough, said insert having an inflow-side with a first section with an oxidation catalyst coating to form said oxidation catalytic converter and having an outflow-side with a second section forming said particle filter, said second section having inlet ducts closed on an the outflow side and having outlet ducts closed on an inflow side of said second section after said first section; at least some of said inlet ducts have a duct surface at least partly provided with an SCR (Selective Catalytic Reduction) catalyst coating, forming at least one SCR catalytic converter reducing nitrous oxides in the exhaust gas by in combination with the reducing agent; at least some of the outlet ducts provided at least partly with a blocking catalyst coating, which forms at least one blocking catalytic converter for decomposing the reducing agent, said blocking catalyst coating being different than said SCR catalyst coating.
