Abstract: A device for the aftertreatment of an exhaust gas of an internal combustion engine flowing through an exhaust line includes at least one dosing unit disposed in an opening of an exhaust pipe of the exhaust line and configured to add an exhaust-gas aftertreatment agent into the exhaust line. The dosing unit is enclosed by a cooling jacket, through which the dosing unit is fastened in the opening of the exhaust pipe. The cooling jacket is at least partially enclosed by a space or chamber delimited at least by the cooling jacket, the exhaust pipe, and a cover plate. The cover plate is connected to the exhaust pipe and spaced apart from the cooling jacket or the dosing unit by a gap. A motor vehicle having the device is also provided.

Abstract: 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.

Abstract: An apparatus for measuring a filling level of a urea container by determining distance using sound waves (ultrasound) emitted by a sensor and echoes thereof, includes a urea container bottom and a sump with an overall height. The sump is adjacent the urea container bottom and located below the level of the urea container bottom. The sump is connected in an open manner to the urea container and bounded at the bottom by a sump bottom. The sensor is accommodated in the vicinity of the sump and, with a sound-emitting surface for emitting sound waves and receiving echoes of the sound waves, is fitted in the urea container with the sound-emitting surface of the sensor at most adjacent the level of the urea container bottom. A motor vehicle having the urea container is also provided.

Abstract: A method for operating a metering apparatus for reducing agent includes providing the metering apparatus with at least one movable pump element movable between upper and lower reversal points to convey reducing agent into an exhaust-gas treatment component, and at least one position transmitter for determining a pass of the movable pump element. In the method, a first detection of a position of the movable pump element is provided by the position encoder. Subsequently, the movable pump element is moved and reducing agent is metered into the exhaust-gas treatment component. Thereupon, a second detection of a position of the movable pump element is provided by the position encoder, and subsequently a first quantity of reducing agent which is metered between the first and second detections is determined. A metering apparatus and a motor vehicle having a metering apparatus are also provided.
