Abstract:
1. System for assisting the regeneration of depollution means integrated in an exhaust line of a motor vehicle diesel engine, in which the engine is associated with common rail supply means for the injection of fuel into the cylinders thereof, according to at least one post-injection, and adapted to implement, at constant torque, through modification of parameters for controlling the operation of the engine, wherein modified parameters control a modified operation mode of the engine during each regeneration phase, at least two regeneration strategies, among which wherein said system comprises means for determining the number of regeneration phases in which regeneration of the depollution means was incomplete and means for comparing this number with predetermined threshold values, to implement the first regeneration strategy for a number lower than the threshold values or the second strategy for a number higher than the threshold values.
