This system in which the depollution means ( 1 ) are associated with oxidation catalyst-formed means ( 2 ), and the engine ( 4 ) is associated with common rail means ( 7 ) for feeding it with fuel and adapted to implement a regeneration strategy using at least one post-injection of fuel into the cylinders, is characterized in that it includes means ( 8 ) for detecting a request for regeneration (req.RG), means ( 9 ) for detecting that the engine is in a stage of idling, means ( 11 ) for acquiring temperature downstream from the catalyst-forming means, means ( 8 ) for determining a maximum duration for post-injection application during the stage of idling on the basis of said temperature, and means ( 7, 8 ) for progressively reducing the post-injection as soon as the duration of use has reached the maximum duration.
