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.
Abstract:
A device for storing or supplying an operating fluid includes a tank with an interior space and a protrusion which protrudes into the interior space and has a circumferential surface. At least one electrode for determining a filling level is disposed radially, running around the circumferential surface. Methods for mounting such a device and for monitoring a reserve filling level as well as a motor vehicle are also provided.
Abstract:
A device for providing liquid reducing agent includes a tank with an interior space and a vessel disposed at least partially in the interior space of the tank. The vessel is at least partially surrounded on the outside by a filter having a filter surface and a filter depth. A delivery unit disposed in the vessel is configured to deliver reducing agent from the tank, through the filter and to an extraction point for reducing agent. A motor vehicle having the device is also provided.
Abstract:
A container for a tank for storing a liquid additive includes a housing having a heater and at least one drivable apparatus for promoting convection in the housing. A motor vehicle includes a tank for storing a liquid additive and an exhaust gas system having a metering or adding device for the liquid additive. A container is inserted into the tank wall and a plurality of functional components is provided in the container for conveying the liquid additive from the tank through the container to the metering or adding device.
Abstract:
A delivery unit for delivering a liquid additive from a tank into an exhaust gas treatment device includes at least a housing which can be mounted on the tank, and a component carrier which carries at least one pump and is fixed in the housing by a clamping plate. A motor vehicle having a delivery unit is also provided.
Abstract:
A device for supplying liquid reducing agent for an exhaust gas treatment device, includes at least a tank with an interior in which reducing agent can be stored, an intake in the interior, a delivery device situated in a separate chamber in a tank bottom of the tank, a line leading from the delivery device to the exhaust gas treatment device and passing through the tank bottom at the separate chamber, and a cleaning layer covering the intake. An intermediate space is formed between the intake and the cleaning layer and contains at least one sponge element which can absorb reducing agent and from which the delivery device can extract reducing agent through the intake. A motor vehicle having the device is also provided.
Abstract:
A device for providing reducing agent includes a tank, a delivery unit disposed at least partially in the tank and having a suction point through which the delivery unit can draw reducing agent out of the tank, and a filter covering the suction point. An intermediate space or chamber is formed between the delivery unit and the filter, and the filter is disposed on the delivery unit in such a way that it can perform a deflection movement away from the suction point if ice forms in the intermediate chamber. A motor vehicle having the device is also provided.
Abstract:
A device for providing a reducing agent for an exhaust gas system includes a system heating unit for heating a reducing agent and at least one heat conduction element transmitting heat from the system heating unit to at least one of the following components: a tank, a delivery line, a filter, a pump, a valve or a sensor. A thermal heating method using a heat pipe and a motor vehicle having the device are also provided.
Abstract:
A container for an operating liquid or fluid for a motor vehicle includes a container wall which delimits an interior space or chamber of the container. The container has a first wall section, a second wall section and at least one discharge line for discharging the operating liquid out of the container. The discharge line extends from the first wall section to the second wall section and can be adjusted in its length to a distance between the first wall section and the second wall section. A method for producing the container and a motor vehicle having the container are also provided.
Abstract:
A dosing valve includes at least a valve housing with a duct, a valve body being movable in order to open and close the dosing valve and a spring exerting a spring force on the valve body and thus holding the valve body in a rest position. The spring is supported on at least one calibration body. The valve body, the spring and the at least one calibration body are disposed in the duct. The at least one calibration body is fastened in the valve housing at least by using a cohesive or material connection. A method for producing the dosing valve and a motor vehicle having the dosing valve are also provided.
