摘要： An electrical connection for an electrical component or electrically heatable honeycomb body, in an exhaust system of an internal combustion engine includes an electrical conductor passing through a metallic jacket of the exhaust system, a bushing and an insulating layer and having an outer connection section with circular cross section. The connection section has a contact surface for connection to a supply line connection piece. The bushing and/or electrical conductor near the bushing can absorb torques up to 3.6, 4.5 or 7 Nm per cm2 of contact surface acting on the connection section and/or an internal or external thread in circumferential direction, by shaping the electrical conductor near the bushing or using structures and/or changes to the cross section or a form-locking construction of the electrical conductor and the bushing. Damage to electrical exhaust components due to external torques, disassembly and maintenance can thus be avoided.

摘要： A supporting pin for supporting an electrically heatable honeycomb body on a first honeycomb body includes a first end region, a second end region, an intermediate region, a core made of electrically non-conductive ceramic material and a metalized surface on at least one end region. The intermediate region is electrically non-conductive and has a length of at least 3 mm, preferably 5 to 15 mm. The supporting pin is particularly suitable for stabilizing electrically heatable honeycomb bodies in exhaust gas treatment systems for internal combustion engines, particularly for motor vehicles. When higher electrical voltages, such as 48 V, are used for electrically heatable honeycomb bodies, good electrical isolation is also assured in exhaust gas systems carrying soot particles with simultaneous safe support and suppression of vibrations.

摘要： An electrically heatable honeycomb body assembly includes an electrical connection of sheet metal layers at a connection pin. A honeycomb body has a metal casing with an inner periphery, through which the connection pin is led in a bushing and electrically insulated. The sheet metal layers are alternately coarsely structured and finely structured or smooth sheets together forming a stack with uppermost and lowermost layers and channels for an axial gas flow between the layers. The connection pin runs radially approximately perpendicular to the layers and is metallically connected to at least two or all of the layers through at least one intermediate piece. The uppermost sheet metal layer preferably runs approximately parallel to the metal casing over at least 35% of the inner periphery and is separated therefrom only by an air gap. Simple production of an operationally safe and very uniformly electrically heatable honeycomb body is provided.

摘要： A honeycomb body includes sheet metal layers forming a central current path to a radial connecting pin. A metal casing has an inner periphery and a feedthrough guiding and insulating the pin. The layers are alternate coarsely structured and finely structured or smooth sheets forming a stack with uppermost and lowermost layers forming axial gas channels. The pin is metallically connected to two or all of the layers directly or through an intermediate piece by an electrically conductive or welded connection. The current path has an electrical resistance per unit length in the connection region being greater than an average electrical resistance per unit length in the stack. The uppermost layer runs approximately parallel to the casing over 35% or 40% of the inner periphery and is separated from the casing by an air gap. Simple manufacture of a highly uniform, reliably operating, electrically heatable honeycomb body is thus possible.

摘要： 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.
