Method and device for regenerating a particle filter integrated into an exhaust line of an internal combustion engine

摘要

The invention relates to a method for regenerating a particle filter (10) integrated into an exhaust line (12) of an internal combustion engine (34), wherein the exhaust gas flows into the filter via an inflow surface (16) and exit the filter via an outflow surface (18). According to the invention, the internal temperature of at least two regions of the filter (10) is monitored during regeneration of the filter; the oxygen content of the exhaust gas is reduced if at least one of the monitored temperatures rises above a critical temperature; the oxygen content of the exhaust gas is increased in order to continue regeneration if all of the monitored temperatures are below said critical temperature.
