This system in which the depollution means ( 1 ) are associated with oxidation catalyst-forming means ( 2 ), and the engine ( 4 ) is associated with common manifold means ( 7 ) for feeding 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 regeneration request (req.RG)), means ( 9 ) for detecting when the engine is idling, means ( 11 ) for acquiring the temperature downstream from the catalyst-forming means, means ( 8 ) for determining, on the basis of said temperature, a maximum quantity of fuel to be injected when post-injections take place while the engine is idling on the basis of said temperature, and means ( 7, 8 ) for progressively reducing post-injection as soon as the quantity of fuel injected has reached the maximum quantity.
