发明名称 System for assisting the regeneration of depollution means for a motor vehicle engine
摘要 The inventive system for assisting in the regeneration of depollution means (1) which is integrated in the exhaust means (3) of a diesel engine (4), wherein the engine (4) is associated with a common rail supplying means (7, 8) for injecting fuel into cylinders thereof using at least one post-injection and for carrying out at least two regeneration strategies by isotorque modifying the parameters of the engine operation control, wherein the first regeneration strategy comprises a first level strategy and a second level strategy and the second regeneration strategy comprising the first level strategies and a sequence alternating the second and second over-calibrated level strategies, thereby making it possible to obtain different thermal levels in the line. The inventive system is characterized in that it comprises means (8) for determining the number of incomplete regenerations of the depollution means and means (8) for comparing said number with the threshold values in order to carry out the first regeneration strategy for the number lower than said threshold values or the second strategy for the number greater than the threshold values.
