| titleOfInvention | Method for the Selective Catalytic Reduction of Nitrogen Oxides in Exhaust Gas from an Internal Combustion Engine, and Exhaust System |
| abstract | A method for the selective catalytic reduction of nitrogen oxides (NO x ) in the exhaust gas from an internal combustion engine includes providing an exhaust system having: an SCR catalytic converter, a reagent addition point upstream of the SCR catalytic converter for adding at least one of a reducing agent and a reducing agent precursor, and a structure which the exhaust gas can at least flow around and is disposed immediately downstream of the reagent addition point. The method determines a nitrogen oxide content of the exhaust gas, determines a temperature of the structure, determines a quantity of reagent required for reduction of the nitrogen oxide content which is determined, determines a temperature of the structure after addition of the quantity of reagent, compares the temperature of the structure with a predeterminable target temperature, calculates the temperature of the structure using at least one of the following measures, if the temperature is lower than the target temperature: adding a reduced quantity of reagent, and increasing at least one of the temperature of the structure and an exhaust gas temperature until the temperature of the structure, after addition of the quantity of reagent, is greater than or equal to the target temperature, and adds the quantity of reagent through the reagent addition point and, if appropriate, increases the temperature. |
