Abstract

A regeneration apparatus for a particulate filter of an exhaust gas system is provided which includes an exhaust gas duct and a catalyst which is integrated into the exhaust gas duct upstream of the particle filter. The exhaust gas system or the combustion engine includes an injection apparatus which is in communication with a fuel reservoir and is able to input fuel, in particular fuel containing hydrocarbons, into the exhaust gas flow. The regeneration apparatus includes a burner and at least one switching device. The burner is able to heat the catalyst to a reaction temperature at which an exothermic reaction of the fuel takes place. The switching device is able to activate and deactivate the burner and/or the injection apparatus selectively in dependence on an operating state of the exhaust gas system. An exhaust gas system for a combustion engine and a method for the regeneration of a particulate filter of an exhaust gas system are also provided.
