ABSTRACT:
The present invention relates to an exhaust system for an internal combustion engine, in particular in a motor vehicle, comprising an exhaust line in which an exhaust treatment device, in particular an oxidation catalyst or a particulate filter is arranged for treating the exhaust gases coming from the internal combustion engine. It is essential to this invention that a device for heating the exhaust gases in the exhaust line is arranged upstream from the exhaust treatment device and is connected to a fuel supply and an air supply, the latter producing primary air and secondary air, and the device has a pre-oxidation zone a downstream post-oxidation zone, such that the pre-oxidation zone is connected to the fuel supply for its supply of liquid fuel and is connected to the air supply for its supply of primary air, while the post-oxidation zone is connected to the air supply for its supply of secondary air.
