    摘要： An exhaust after treatment system for a vehicle includes an exhaust outlet pipe, having a first end that is connectable to a vehicle engine, for receiving exhaust gases from said vehicle engine, and having an outlet opening at a second end, arranged to eject the outlet gases, a catalytic converter, connected to the exhaust outlet pipe; and an electric heater element which is in heat conducting contact with the catalytic converter and adapted for pre-heating the catalytic converter. The heater element is positioned downstream of the catalytic converter with respect to the first end. Upon the vehicle being started, the heater element is switched on and gases are flowed from the second end, in the direction of the first end of the exhaust outlet pipe, through the catalytic converter for a pre-set period of time prior to passing exhaust gases from the engine towards the outlet opening at the second end.

    摘要： A connection unit for connecting an electrical supply line to an exhaust gas heater of an exhaust system of an internal combustion engine includes an electrically conductive connection element. The connection element has a heater connection region in a first end region and a supply line connection region in a second end region. A carrier has a receiving opening, wherein the connection element is arranged and has a support region. A first insulating element is arranged in the opening and surrounds the support region. A second insulating element is arranged on a first end face of the carrier. The connection element is supported with respect to the first end face via the second insulating element. A third insulating element is arranged on a second end face of the carrier. The connection element is supported with respect to this second end face via the third insulating element.

    摘要： An exhaust gas heater for an exhaust gas system of an internal combustion engine includes a carrier arrangement, a heating-conductor arrangement, carried on the carrier arrangement and having at least one heating conductor through which a current flows with at least one heating conductor being carried in an electrically insulated manner with respect to the carrier arrangement by at least one carrier-element supporting unit and/or with at least one heating conductor being carried in an electrically insulated manner with respect to a further heating conductor by at least one heating-conductor supporting unit. A connecting arrangement securely connects the heating-conductor arrangement to the carrier arrangement and also a length-compensating arrangement for compensating for different thermal expansions of components of the exhaust gas heater.
