Abstract
The invention concerns a procedure for controlling a metering device for metering fuel into the exhaust gas duct of a combustion engine for the regeneration of a particle filter, whereby the metering device supplies the fuel to the exhaust gas duct over a security valve, a first fuel pipe, a metering valve, a second fuel pipe and an injection check valve and whereby the pressure of the fuel is determined between the metering valve and the injection check valve in the second fuel pipe. It is thereby provided that an opening pressure of the injection check valve is determined from the pressure course between the metering valve and the injection check valve.
