Abstract: A delivery unit for extracting liquid additive from a tank can be mounted on the tank and includes a fill level sensor for measuring the fill level of liquid additive in the tank. The fill level sensor is set up to emit waves into an emission region of the tank, and the fill level can be measured by using a propagation time measurement of the waves reflected by a liquid surface and striking the fill level sensor again. At least one first reference surface extends at least partially into the emission region and is at a first distance from the fill level sensor. The at least one first reference surface is disposed on a separate calibration component mounted on an outer side of a housing of the delivery unit. A tank for storing liquid additive, a motor vehicle and a method for monitoring a fill level 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.

Abstract: A device for exhaust gas treatment in an exhaust system of an internal combustion engine, in particular in a motor vehicle, includes an electrically heatable honeycomb body through which an exhaust gas can flow. The honeycomb body is disposed in a casing tube and has at least one current-conducting structure with electric insulation for voltages greater than 24 V. A current-generating pulsed voltage is applied to the structure to heat the honeycomb body. It is thus possible for heating elements in the exhaust-gas flow to be powered by an on-board electrical system voltage of for example 48 V. A method for operating the honeycomb body is provided with which, even at operating voltages greater than 24 V, the generation of heat in the electrically heatable honeycomb body can be kept in a desired range by adjustment of a pulse width and/or repetition frequency of the pulsed voltage.
