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.

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.
