摘要： A motor vehicle emission control system includes a three zone catalytic converter component having a honeycomb support body with catalytically active coating having a precious metal content applied on the channel walls. The first coating zone extends in the longitudinal direction from the inlet-side end to a first coating boundary and has a first precious metal content. The second coating zone extends in the longitudinal direction from the first coating boundary to a second coating boundary situated downstream from the first coating boundary and has a second precious metal content that is lower than the first precious metal content. The third coating zone extends from the second coating boundary to the outlet-side end and has a third precious metal content that is lower than the second precious metal content. The coating has oxidation catalyst activity and is free of rhodium.

摘要： A method for operating an internal combustion engine involves using an injection valve to post-inject fuel into at least one cylinder of the internal combustion engine in order to help regenerate a particulate filter that is arranged in an exhaust system of the internal combustion engine, downstream of an oxidation catalyst. A closing moment of a discharge valve of a cylinder of the internal combustion engine is advanced when the temperature of the oxidation catalyst is in a first temperature range, and the post-injections are performed when the temperature of the oxidation catalyst is in a second temperature range, an upper limit of the first temperature range having a lower value that an upper limit of the second temperature range.
