Abstract: A method for operating a delivery device for delivering a reducing agent from a reducing agent tank into an exhaust treatment device of an internal combustion engine of a motor vehicle, includes at least intermittently carrying out a ventilation process of the delivery device during operation of the internal combustion engine. A registration of a ventilation process first occurs. A timing unit having a preset time interval and/or a mass-flow summing unit having a preset total mass flow is then actuated. When the preset time interval and/or the preset total mass flow is reached, the ventilation process is then carried out. In particular, monitoring the delivery device by a pressure sensor can thus be omitted. A delivery device for delivering a reducing agent is also provided.

Abstract: A method for determining an amount of liquid removed from a tank per unit time includes discontinuously feeding the liquid to exhaust gas of an internal combustion engine by at least feeding the liquid through an injection line into the exhaust gas, measuring pressures simultaneously at least at two points in the injection line and determining an amount of liquid fed in per unit time from the measured pressures. The amount of liquid removed between a first point in time and a second point in time is further derived by integrating the amounts of liquid removed per unit time over a period of time from the first point in time to the second point in time. The method allows the precise consumption of the liquid to be calculated and the remaining amount of liquid in the tank to be additionally determined. On-board diagnosis is further possible with the method.
