Abstract
A method for monitoring regeneration of a pollution-removal system, relying on introduction of fuel into exhaust gases by delayed injections of fuel into certain combustion chambers of an engine and/or direct injections into an exhaust system upstream of a filter depending on an inlet temperature of the system. Introduced fuel delivery 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 of the exhaust system.

A method for controlling regeneration of a depollution system including an oxidation catalyst and a filter, based on introduction of fuel into exhaust gases via delayed injections of fuel into certain combustion chambers of an engine and/or by direct injections into an exhaust line upstream from the filter by virtue of an injector dedicated to the exhaust line, as a function of temperature at an inlet of the system, wherein the introduced fuel flow is assigned to the direct injections into the exhaust line and/or to the delayed injections into certain combustion chambers according to a value of a wall temperature of the exhaust line.
