Abstract

The invention relates to a procedure for a switching pressure calculation at a metering valve of a fuel metering device for metering fuel into an exhaust gas system of a combustion engine with a component that is assigned to the exhaust gas system of the combustion engine for a regeneration, for a temperature impinge and/or for a thermo management, whereby the fuel is injected before this component in streaming direction of the exhaust gas. The invention concerns furthermore a corresponding device for implementing the procedure.
