| description | A procedure to operate a metering device of an exhaust gas emission control system of an internal combustion engine and a device to implement the procedure are proposed. At least one component in an exhaust gas emission control configuration of the exhaust gas emission control system requires at least in certain operating conditions a reagent substance, which the metering device provides, in which a connecting line is disposed. After the emergence of a metering demand signal a reagent substance rate-set point is established. The reagent substance rate-set point is either established immediately when the metering demand signal occurs and subsequently no longer changed until the connecting line is filled with the reagent substance; or the reagent substance rate-set point is only then established if the connecting line is filled with the reagent substance. An overdose of the reagent substance is avoided with the procedural approach according to the invention. |
