    Abstract: An injection device for injecting a fluid into an exhaust-gas treatment device includes an injector positioned in an injector holder. The injector has a supply opening and a component of the injector holder extends into the supply opening. The injection device is suitable, in particular, for supplying a urea/water solution into an exhaust-gas treatment device of a motor vehicle. The component is preferably rigid in the longitudinal direction and can be compressed in the radial direction by way of a deformable rubber shell, in order to compensate for the volumetric expansion of the solution if it freezes. A motor vehicle having the injection device is also provided.

    Abstract: 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. A motor vehicle having the device is also provided.
