Abstract

Procedure for operating an electromagnetically operated metering valve, which is impinged with a metering signal, which determines the metering of a reagent or a precursor of a reagent that has to be injected into the exhaust gas area of a combustion engine, is thereby characterized, in that the reagent pressure is detected at an opened metering valve in a default cycle, which indicates the reagent flow and in that the reagent flow is added over the opening time of the valve for determining the actual metering amount.
