Abstract: A catalyst body for an electrically heated catalyst has an electrical contacting assembly, which is arranged on the catalyst body and comprises an electrical conductor embedded in the catalyst body and extending in a longitudinal direction of the catalyst body and at least up to one end face of the catalyst body.

Abstract: A method for production of an exhaust-gas routing device that has a housing, an elongated substrate, and a compensating element, includes the following steps. At least one parameter of the substrate and/or of the compensating element is determined A target parameter, which describes a variable linked to a target geometry of the housing, is determined based on the measured parameter of the substrate and/or of the compensating element. The substrate and the compensating element are arranged in the housing, and the housing is deformed with an overpressure factor which is determined on the basis of at least one previous deformation of a previously manufactured device. The housing is measured after the deformation, and the thus-established values are compared with the target parameter. An overpressure factor for the deformation of a subsequently manufactured device is adapted if a deviation from the target parameter is detected upon measuring which lies above a defined threshold value.

Abstract: An electrically heated catalyst has a catalyst body and a housing at least circumferentially surrounding the catalyst body. An electrical contacting assembly is arranged on a shell surface of the catalyst body, the electrical contacting assembly comprising a surface electrode arranged directly on the catalyst body and a contacting element connected to the surface electrode. The contacting element is rigid and has a screw thread.

Abstract: An exhaust gas treatment device has a housing and a hollow body through which exhaust gas flows and which is accommodated in the housing. The hollow body consists at least partly of a gas permeable substrate. The hollow body is connected at least one end to a wall member arranged in the housing and formed to be flexible in the axial direction.

Abstract: A method for manufacturing exhaust gas ducting devices provides each device with an outer housing having an insert clamped therein, wherein the insert comprises a substrate traversed by exhaust gas, and an elastic compensating element surrounding the substrate. The method includes spreading each individual compensating element on a base and deforming the compensating element substantially vertical to the base by exerting a pressure such that the entire compensating element is subjected to a full-surface load. Then a setpoint deformation of the compensating element is determined, which is necessary to achieve a specified setpoint pressure. The method further includes determining at least one parameter of the substrate individually, placing the compensating element around the substrate, and mounting the insert thus obtained in an outer housing having inside dimensions that correspond to outside dimensions of the insert with the determined setpoint deformation.
