Abstract (en)

[origin: WO2007119015A1] Method for monitoring the regeneration of a pollution-removal system (8), relying on the introduction of fuel into the exhaust gases by delayed injections of fuel into certain combustion chambers of the engine and/or direct injections into the exhaust system upstream of the filter depending on the inlet temperature of the system, characterized in that the fuel delivery (Q<SUB>red</SUB>) introduced is assigned to direct injections into the exhaust system and/or to delayed injections into the combustion chamber according to the value of the wall temperature (T<SUB>paroi</SUB>) of the exhaust system.
