摘要： A connection unit connects an electrical supply line to an exhaust-gas heater of an exhaust system. The connection unit includes a connection element having an electrically conductive connection-element body. The connection element has an exhaust-gas heater connection region in a first axial end region and has a supply-line connection region in a second axial end region. The supply-line connection region includes an end portion of the connection-element body and a radial projection adjoining the end portion. A carrier element fixes the connection unit to an exhaust-system component. The carrier element has a carrier-element opening wherethrough the connection-element body passes. A support unit axially and radially supports the connection element on the carrier element.

摘要： A muffler for an exhaust gas system of an internal combustion engine. The muffler has a muffler housing having at least two interconnected housing shells delimiting a muffler interior. Each housing shell has a connecting edge extending away from the muffler interior. The housing shells are mutually connected by material bonding in the region of their mutually adjacent housing shell connecting edges. An insulating arrangement covers at least regions of the inner side of one of the housing shells. The insulating arrangement has an insulating shell with an insulating shell connecting edge extending away from the muffler interior and the insulating shell is arranged with the insulating shell connecting edge between the mutually adjacent connecting edges of the housing shells and is connected by material bonding to the connecting edges of the housing shells in the region of the insulating shell connecting edge.

摘要： An exhaust gas heater for an exhaust gas system of an internal combustion engine includes a heating conductor. The heating conductor is constructed from flat material which is elongate in a heating-conductor longitudinal direction and has heating-conductor broad sides situated opposite one another in a heating-conductor thickness direction and heating-conductor flat sides situated opposite one another in a heating-conductor width direction. A plurality of formations, which follow one another in the heating-conductor longitudinal direction or/and follow one another in the heating-conductor width direction, are oriented substantially in the heating-conductor thickness direction and have varying formation heights in the heating-conductor width direction.

摘要： A compression jaw assembly unit for a compressing device for compressing tubular metal parts includes a compression jaw carrier (17) and a compression jaw (16), provided at the compression jaw carrier (17), with a compressing surface (18) that is oriented essentially facing away from the compression jaw carrier (17) and is curved transversely to a compression jaw longitudinal direction (LB) in a compression jaw transverse direction (QB). The compression jaw (16) includes a fixed compression jaw segment (22), which is fixed to the compression jaw carrier (17) and provides a compressing surface segment (24), and at least one movable compression jaw segment (26, 28) providing a compressing surface segment (30, 32). The at least one movable compressing surface segment (26, 28) can be moved in a direction of movement (B) in relation to the fixed compressing surface segment (22) against the prestressing action of a prestressing device (42).

摘要： An exhaust gas heater for an exhaust gas system of an internal combustion engine includes a carrier arrangement and a heating conductor arrangement. The heating conductor arrangement is carried on the carrier arrangement and exhaust gas can flow therethrough in a main exhaust gas flow direction. The heating conductor arrangement includes at least two heating conductors arranged following one another in the main exhaust gas flow direction. The carrier arrangement includes at least one carrier element having a fixing region lying radially on the outside relative to an exhaust gas heater center axis and is configured for fixing to an exhaust gas guidance housing. The fixing region at least partially does not radially overlap a radially outer lying conductor region of at least one heating conductor of the heating conductor arrangement in at least one, preferably several circumferential regions.

摘要： An exhaust gas treatment assembly includes a housing and an exhaust gas treatment section accommodating chamber in the housing for accommodating an exhaust gas treatment section therein so as to permit the treatment section to be removed from the housing. An exhaust gas supply duct leads to the housing and is open to the housing via a housing inlet region. A main mixing section accommodating chamber accommodates a main mixing section in such a way that the main mixing section can be removed from the housing. A first exhaust gas treatment section inlet region is open to the housing inlet region to receive exhaust gas from the exhaust gas supply duct. A first exhaust gas treatment section outlet region is open to a main mixing section exhaust gas inlet region of the main mixing section.

摘要： A heating unit for an exhaust-gas system of an internal combustion engine includes a heating-unit housing for conducting an exhaust-gas in a main flow direction. A plurality of heating elements are arranged in the heating-unit housing and are shaped in a meandering manner. Each heating element has a plurality of plate-like heating sections which follow one another in a heating-element longitudinal direction. The heating sections of each heating element are connected to one another via respective connecting sections. Each heating element has two connection regions which are arranged at a distance from one another. In each connection region, the heating elements are electrically conductively connected to a connection region of a further heating element.

摘要： A connection element for an exhaust system of an internal combustion engine includes a connection element body extending in the direction of a connection element longitudinal axis. An inner circumferential surface of the connection element body delimits an exhaust gas passage of the connection element and a connecting flange extends radially outward from the connection element body and surrounds the longitudinal axis. The connecting flange has an abutment surface oriented in the direction of a first axial end of the connection element body. A section of the connection element body defines the first axial end thereof. A centering section has a centering outer circumferential surface and a depression surrounds the longitudinal axis and has a depression surface which is offset axially in the direction away from the first axial end with respect to the abutment surface.
