摘要： A tank for a reducing agent includes a tank wall having an outer side and an interior at least partially delimited by the tank wall. A sensor is disposed at the tank wall and has a first electrical contact and a second electrical contact. The first electrical contact and the second electrical contact communicate in an electrically conductive manner with the interior, extend through the tank wall from the interior to the outer side of the tank wall and are disposed at a first spacing of less than 5 cm from one another. A motor vehicle having the tank is also provided.

摘要： A method for operating a reducing agent delivery device having a liquid reducing agent tank, an injector dispensing reducing agent into an exhaust treatment device, an internal combustion engine and a reducing agent line from tank to injector, includes conveying the reducing agent from tank to injector with a pump and providing a pressure sensor in the line. The method includes, repeatedly: determining and providing supply pressure for the injector in the delivery device with the pump, calculating an injector opening time from a determined injection volume and supply pressure and opening the injector at the calculated injector opening time. A venting procedure at a point in time includes: determining an increase of a pressure conveying volume characteristic in the delivery device, calculating an air bubble volume by comparing the increase to a target increase, and conveying a conveying volume through the injector. A motor vehicle is also provided.

摘要： A method for operating a tank for reducing agent, in particular aqueous urea solution, having a sensor with a first electrical contact and a second electrical contact, includes initially determining a conductance value for liquid reducing agent, a conductance value for frozen reducing agent and a conductance value for air in steps a.1) to a.3. A voltage is then applied between the first electrical contact and the second electrical contact in step b. A conductance value between the first electrical contact and the second electrical contact is then determined in step c. The conductance value determined in step c) is then compared to the conductance values determined in steps a.1) to a.3) and a determination is made as to if liquid reducing agent, frozen reducing agent, or air is present in step d). A motor vehicle in which the method is carried out, is also provided.
