Abstract:
A method and an apparatus for metering a reducing agent in which the reducing agent is delivered, via a line and a final control element that regulates the metering, in particular a metering valve, to a catalytic converter assembly for removing nitrogen oxides from the exhaust gases, in particular of a Diesel engine; a pressure drop in the line dictated especially by gas inclusions is detected, and the line is ventilated via the final control element.
