Abstract

See full text

A method and to a device for the regeneration of a particle filter arranged in the exhaust gas tract of an internal combustion engine with at least one NO oxidation catalyst for the oxidation of NO, especially to NO2, which is arranged upstream of the particle filter and through which an exhaust gas stream flows. At least one heater, especially a heating catalyst, through which another gas stream, i.e., a second exhaust gas stream, flows and which heats the additional gas steam, is provided upstream of the particle filter. The heated additional gas stream is mixed upstream of the particle filter with the exhaust gas stream coming from the NO oxidation catalyst, i.e., the gas stream loaded in particular with NO2.
