Abstract (en)
[origin: WO2007045542A1] A method for operation of an internal combustion engine (10), comprising an exhaust treatment device (16) in the exhaust system (13) thereof, with application of a reagent under given operating conditions of the internal combustion engine (10) and/or the exhaust treatment device (16) and a device for carrying out the method are disclosed, wherein a correction parameter (ti Korr, m Korr) is determined for a reagent signal (S Rea), describing the amount of reagent to be introduced into the exhaust system (13) and the correction parameter (ti Korr, m Korr) is determined by means of a comparison of a measure (m Ist) of the actual amount of the reagent in the exhaust system (13), which should be introduced based on a measure (m Soll) of a pre-determined set amount and the measure (m Soll) of the set amount. The above method permits a particularly exact maintenance of the amount of reagent introduced into the exhaust system (13) in accordance with the pre-determined measure (m Soll) for the set amount.
