    Abstract: A mounting includes at least one electrode producing electric fields in an exhaust gas line, a disk of electrically insulating material having inflow and outflow sides and openings for exhaust gas, and at least one electrical conductor fastened to and/or in the disk. The electrical conductor is covered by the electrically insulating material at least on the inflow side and in electrical contact with the electrodes extending toward the outflow side. Since the electrical conductor is completely surrounded by insulating material during operation, an area that must be covered by a soot layer for a leakage current to develop is increased. The leakage length increases and one or more electrodes are in the exhaust gas at the same time. The soot particles deposited on the mounting and the exhaust gas line, need to be removed less often. An exhaust line device having at least one mounting 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.

    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.

    Abstract: An exhaust-gas treatment device includes a honeycomb body wound and/or stacked with at least partially structured sheet-metal layers forming channels through which an exhaust gas can flow in axial direction from an inlet side to an outlet side. A first section of the sheet-metal layers ends flush at a first end surface associated with at least one of the sides and a second section of the sheet-metal layers ends at a second end surface associated with at least one of the sides. A spacing is provided between the first and second end surfaces because a first axial length of the first section is greater than a second axial length of the second section. The spacing forms a receptacle receiving a heating body, producing a simple electrically heatable exhaust-gas treatment device into which a heating body can be integrated during or after production of the honeycomb body.
