    摘要： The invention relates to an exhaust gas post treatment system for an internal combustion engine, including an intake device for taking hydrocarbons into an exhaust gas pipe carrying the exhaust process gas from the internal combustion engine and a treatment device through which exhaust process gas flows downstream of the intake location and which increases the exhaust process gas temperature by means of oxidation of the hydrocarbons taken in. The invention specifies an exhaust gas post treatment system and a method for operating such an exhaust gas post treatment system which can be implemented cost-effectively. This is achieved in that the treatment device has catalytically coated components, in that the hydrocarbons are at least partly evaporated in the intake device and are modified chemically by means of cracking reactions and/or by means of partial oxidation, and in that the proportion of platinum, at least in a subregion of the catalytic coating of the components, is less than 50% of the overall mass of all the catalytically active substances in this sub region of the coating.

    摘要： Described is a method for cleaning the exhaust gases of internal combustion engines, which method is suitable for reducing harmful gases and particle emissions. Here, the exhaust gas to be cleaned is conducted, under operating conditions, with a discontinuous profile of the air ratio λ across a wall-flow filter substrate which comprises a catalytically active coating containing one storage material. The storage material is suitable for temporarily storing one or more exhaust-gas components under certain operating conditions and releasing said exhaust-gas components again in a targeted fashion in the event of a suitable change in the operating conditions. The coating is configured such that the component has a gradient of the storage material concentration and/or of the total coating amount, with the highest concentration of the storage material in the longitudinal direction of the component being present on the inflow side. At least 60% by weight of the storage material in relation to its total amount is present in the walls between inflow and outflow ducts, and at least 50% by weight of the storage material in relation to its total amount is present in a first, inflow-side zone in the wall-flow filter substrate.
