摘要： An exhaust system for an internal combustion engine includes an exhaust gas-carrying component (16) with an outer wall (14), a heat conductor element (12) with a jacket (40) and with a heat conductor device (50) enclosed by the jacket (40). A pass-through device (22) provides a gastight passing of the heat conductor element (12) through the outer wall (14) of the exhaust gas-carrying component (16). The pass-through device (22) includes a pass-through opening (26) in the outer wall (14), which pass-through opening (26) is traversed by the heat conductor element (12), and a connection element (24), which is connected in a gastight manner to the heat conductor element (12), on the one hand, and to the outer wall (14), on the other hand.

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 heater for an exhaust-gas system of an internal combustion engine includes a carrier arrangement and a heating-conductor arrangement, which is carried on the carrier arrangement, and which has at least one heating conductor. The carrier arrangement includes an annular first carrier element, which surrounds an exhaust-gas-heater longitudinal axis, and a plurality of second carrier elements, which are formed separately from the first carrier element and are connected to the first carrier element in a first connecting region and to a coupling region of the heating-conductor arrangement in a second connecting region.

摘要： An exhaust gas heater for an exhaust gas system of a combustion engine includes a carrier and a heating conductor supported on the carrier. The heating conductor includes a heating region arranged on an axial side of the carrier, wherein the heating conductor is electrically uninsulated in its heating region at least in part. A holding arrangement has at least one holding unit which holds the heating conductor on the carrier in its heating region. The holding unit includes at least one electrically conducting holding block which is in contact with the heating conductor in an electrically uninsulated region of the heating region. The holding block is electrically insulated with respect to the carrier.

摘要： An exhaust gas heater for an exhaust gas system of a combustion engine includes a carrier and at least one heating conductor through which a current flows. The heating conductor is mounted on the carrier. The heating conductor is provided via separation from a metal flat material blank. A method of making an exhaust gas heater includes a step of separating the heating conductor from the metal flat material blank.

摘要： An exhaust gas heater for an exhaust gas system of an internal combustion engine includes a carrier arrangement through which exhaust gas can flow in the direction of an exhaust gas heater longitudinal axis. The exhaust gas heater includes at least one heating conductor supported on the carrier arrangement. The at least one heating conductor is made with bent flat material for the provision of a heating conductor profile which is meandering at least in regions thereof. The heating conductor flat end faces are opposite one another and the heating conductor broad sides are opposite one another.
