Abstract: The system for assisting the regeneration of depollution means (1) integrated in an exhaust line (2) of a heat engine (3) of a motor vehicle, by switching the engine between operation in lean mode and operation in rich mode in accordance with various parameters (7, 8) for controlling the operation of the engine, is characterized in that it comprises means (9) for measuring the temperature of the gases for supplying the engine and means (8) for correcting at least one parameter for controlling the operation of the engine in rich mode as a function of the measured temperature.

Abstract: The invention provides a system for providing assistance in regenerating depollution means included in an exhaust system of a motor vehicle engine, the system comprising means for controlling the operation of the engine in order to switch the engine between operation in a standard lean mode and operation in a nominal rich mode for regeneration by using post-injection of fuel into the cylinders of the engine and by modifying at least one engine operation control parameter.

Abstract: A system for assisting regeneration of depollution included in an exhaust system of a motor vehicle engine by switching the engine between operation in lean mode and operation in rich mode, depending on various parameters for controlling the operation of the engine, which includes a lambda probe placed in the exhaust gas outlet from the engine, and which corrects at least one of the operating parameters of the engine in order to provide closed-loop regulation of the richness of the exhaust gas about a target value while the engine is operating in rich mode.
