Abstract (en)
[origin: WO2004038205A1] The invention concerns a system for assisting regeneration of a storage/release NOx trap integrated in an exhaust line (5) of a motor vehicle diesel engine (4). The invention is characterized in that it comprises means for gas intake into the engine and means for injecting fuel (11) into the cylinders thereof in the form of at least pilot and main injections and means for controlling (12) said gas intake and/or fuel injection means for periodically switching the engine (4) from a standard lean-mixture operating mode, for storing NOx in the trap (6) to a rich-mixture regenerating operation, with at least two pilot injections and one main injection, for releasing NOx from the trap (6) and regenerating the latter.
