ABSTRACT:
Process for the decontamination of the emissions from an internal combustion engine (1), the exhaust line (5) of which is equipped with a particle filter (7), characterized in that an NOxtrap additive is added to the fuel, so that the said additive is found trapped within the soot, and in that, at the time of the regenerations of the particle filter (7), the engine (1) is controlled with a richness balance according to at least one alternation of a lean-mixture phase and of a rich-mixture phase, in order to bring about the adsorption of the NO2from the exhaust gases by the said additive during the lean-mixture phase or phases and to bring about the oxidation of the soot particles by the adsorbed NO2during the rich-mixture phase or phases.Device for the implementation of this process.
