A method for operation of an internal combustion engine, comprising an exhaust treatment device in the exhaust system thereof, with application of a reagent under given operating conditions of the internal combustion engine and/or the exhaust treatment device and a device for carrying out the method are disclosed, wherein a correction parameter is determined for a reagent signal, describing the amount of reagent to be introduced into the exhaust system and the correction parameter is determined by means of a comparison of a measure of the actual amount of the reagent in the exhaust system, which should be introduced based on a measure of a pre-determined set amount and the measure of the set amount. The above method permits a particularly exact maintenance of the amount of reagent introduced into the exhaust system in accordance with the pre-determined measure for the set amount. |
