    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.

    Abstract: A method for regulating an ionization device in an exhaust gas after-treatment device of an internal combustion engine, includes placing at least one cathode at a distance from an anode in the exhaust gas after-treatment device, applying a high voltage between the at least one cathode and the anode, predefining a first value for the high voltage, detecting a current generated by the high voltage between the at least one cathode and the anode and predefining a second value for the high voltage if the detected current exceeds a predefinable first current intensity for a predefinable number of times. A motor vehicle in which the method is carried out is also provided.

    Abstract: A device for treating a gas stream, especially an exhaust-gas stream of an internal combustion engine, includes at least one radial chamber radially conducting the gas stream and extending substantially radially from a central region to an outer collecting chamber. First and second, preferably parallel, substantially disk-shaped walls delimit the chamber. Electrodes project from the first wall into the chamber. The first wall is formed of electrically insulating material having the electrodes fastened therein and electrically interconnected by electrical conductors in or on the insulating material. Two or more chambers may be disposed, axially in series, around the central region. Very effective treatment of exhaust gas with an electric field for ionization or generating a plasma can be provided over a relatively short structural length in a flow direction. Electric fields running transversely to the flow direction provide new possibilities for selecting various parameters of the treatment device.

    Abstract: A device for treating exhaust gas containing soot particles includes at least one ionization element for ionizing soot particles, at least one filter element having at least one section to which an electrical potential can be applied, and at least one flow-directing device. The flow-directing device can influence a flow of the exhaust gases in such a way that the soot particles can be prevented from being deposited on at least one electric insulation of the ionization element or of the filter element or can be removed therefrom. Soot particles are therefore effectively prevented from being deposited on electric insulation of exhaust gas cleaning components, thereby preventing short-circuits from being produced and permitting exhaust gas systems to be safely operated.

    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.
