Patent ID: 8756927

Claim:
A method for the regeneration of a particle filter arranged in the exhaust gas tract of an internal combustion engine, the method comprising: dividing an exhaust gas flow exiting the internal combustion engine into a first and a second exhaust gas stream; oxidizing the first exhaust gas stream by an oxidation catalyst configured for the oxidation of at least NO to NO 2 , the oxidation catalyst arranged in a first exhaust gas line upstream of the particle filter and through which the first exhaust gas stream flows; heating the second exhaust gas stream in a second exhaust gas line by at least one heater, configured as a heating catalyst to heat the second exhaust gas stream upstream of the particle filter, said first and second exhaust gas lines being parallel to each other; thereafter mixing the heated second exhaust gas stream with the first exhaust gas stream loaded with NO 2 coming from the NO oxidation catalyst, said mixing being performed upstream of the particle filter; metering at predetermined times in predetermined quantities hydrocarbons into the second exhaust gas stream upstream of the at least one heater by a metering device; oxidizing the hydrocarbons; and supplying a predetermined amount of a charging-air stream to the second exhaust gas stream upstream of the heater during at least one of predetermined times, when an exhaust gas temperature exceeds a certain value, when lambda falls below a predetermined value, and when the oxygen falls below a predetermined value.
