摘要： A delivery device for delivering a liquid additive out of a tank to an exhaust-gas treatment device includes a delivery duct with an overall volume and a pump disposed in the delivery duct. The delivery duct has a flexible wall portion, downstream of the pump in a delivery direction, with an outer side of the flexible wall portion situated opposite the delivery duct and bearing against a stop when a pressure in the delivery duct lies in a predefined operating pressure range. A spring element which is disposed on the outer side is constructed to deform the flexible wall portion in such a way that the overall volume is reduced in size when the pressure in the delivery duct is lower than a threshold pressure. A method for compensating a formation of ice in a delivery device and a motor vehicle having a delivery device are also provided.

摘要： A method for heating a delivery system providing reducing agent to an exhaust gas treatment device of an internal combustion engine having electrical components, includes determining a temperature in the delivery system, determining thermal energy required for error-free operation of the delivery system in a time interval, and introducing the required thermal energy into the delivery system by operating the electrical components within the time interval. The electrical components are activated at a time offset of at least 30 seconds. The required energy is determined so that the quantity of reducing agent to be delivered hourly is provided in liquid form at least four times after the time interval. The method prevents overloading of an electrical system of a motor vehicle when heating the delivery system and prevents ice cavity formation in a reducing agent in a tank. A motor vehicle having a delivery system is also provided.

摘要： A device for supplying a liquid additive for a motor vehicle includes a tank for storing the liquid additive and a delivery unit for delivering the liquid additive out of the tank. A sensor emits and receives waves and is configured to measure a fill level of the liquid additive in the tank by way of a propagation time measurement of the waves along a measurement path to a liquid surface in the tank and back to the sensor. The measurement path runs at least partially through a measurement duct. At least one back-flushing line ends in the measurement duct so that flushing of the measurement duct to the tank can be performed, in such a way that the measurement duct is kept clean and/or is cleaned.
