Abstract

The invention relates to a method for regenerating a particulate filter arranged in the exhaust gas tract of an internal combustion engine, having at least one NO oxidation catalytic converter arranged upstream of the particle filter for the oxidation of NO, in particular to form NO2, and having at least one heating device for raising the temperature of an exhaust gas stream. According to the invention, by means of the at least one heating device (8), a defined quantity of thermal energy is produced, with which the temperature of the NO oxidation catalytic converter (4) is set in a defined temperature range, wherein the temperature range is preferably predefined as a function of a level of loading of the particulate filter (6) with carbon black and/or of an efficiency of the NO2-based regeneration of the particle filter (6) by means of the quantity of NO2 formed at the at least one NO oxidation catalytic converter (4)..
