摘要： In an electrically heated catalyst which is arranged in an exhaust passage, electric leakage is suppressed as much as possible. The electrically heated catalyst comprising: a heat generation element; an electrode; a case; an electrode chamber; and an electrically insulating holding member that is inserted between the outer peripheral surface of the heat generation element and the case, and has an abutment joint portion formed by a pair of end faces which connect from an upstream side end portion to a downstream side end portion of the holding member, and which are arranged in opposition to each other, and an opening portion which is constructed so as to form a predetermined space connected with the electrode chamber in the surrounding of the electrode. The abutment joint portion is arranged in a position which excludes the opening portion, and in which it is not exposed to the electrode chamber.

摘要： Reductant is metered into an engine exhaust gas after-treatment system upstream of an SCR catalyst at engine exhaust gas temperatures both less than and greater than a DEF dosing threshold temperature to render the catalyst effective in reducing NOx without creating undesired reaction products which would impair effectiveness of the after-treatment system at engine exhaust gas temperatures less than the DEF dosing threshold temperature.

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.
