Abstract: A method and system controls a regeneration of a particle filter of an internal combustion engine. A first value is measured for the oxygen content in exhaust gas upstream from the particle filter. A second value is measured for the oxygen content in exhaust gas downstream from the particle filter. The particle filter is determined to be free of soot when the second value for the oxygen content is equal to the first value for the oxygen content.

Abstract: A method and system for regenerating a gasoline particle filter of an internal combustion engine is provided in which a value (Q) for a quantity of soot collected inside of the gasoline particle filter and a value (T) for a temperature of the gasoline particle filter are determined. The internal combustion engine is operated in a lean mode when the value (Q) for the soot quantity is greater than a first threshold, and the value (T) for the temperature of the gasoline particle filter is greater than a threshold.
