Abstract
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 oxidation of the hydrocarbons taken in. An exhaust gas post treatment system and a method for operating the same, in that the treatment device has catalytically coated components, the hydrocarbons are at least partly evaporated in the intake device and are modified chemically by cracking reactions and/or by partial oxidation, and 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.
