摘要： The invention relates to a volume quantity dispensing unit, in particular as a unit for metering an aqueous solution such as a urea/water solution, which can be used in an exhaust gas aftertreatment unit (17), comprising a pressure transducer (1), in particular comprising an electric pressure sensor, the volume quantity dispensing of the volume quantity dispensing unit following an electric signal (2) and the volume quantity dispensing unit being calibrated. There is provided at least one means (3) for changing a pressure value (4), which means changes the pressure value (4) in such a way that the pressure value (4), which is intended to correspond to the pressure in the volume quantity dispensing unit, is an input signal for a volume quantity (5) to be dispensed.

摘要： An exhaust gas aftertreatment system and method are provided. The system comprises a controller, a pump, and a volume quantity dispensing unit. The volume quantity dispensing unit comprises a pressure transducer comprising an electric pressure sensor, at least one fine atomizing nozzle for apportioning the aqueous solution directly into an exhaust gas flow, and at least one means for changing a pressure value. The means changes the pressure value in such a way that a pressure output signal from the pressure transducer to the controller is modified from an actual pressure value sensed by the pressure sensor. A first signal provided by the controller to the pump and a second signal provided by the controller to the volume quantity dispensing unit are adapted based on the output signal from the pressure transducer and a further signal indicative of an operating state of the internal combustion engine.
