Abstract:
A method and a device for metering a reducing agent is described, which is used for mass regulated metering of a reducing agent, in particular urea or a urea-water solution for the exhaust gas treatment of the exhaust gas of a diesel engine in particular. The device includes a mass sensor for measuring the reducing agent mass flow into the catalytic converter system.
