SYSTEM FOR THE REGENERATION OF A PARTICLE FILTER OF AN EXHAUST LINE

摘要

A system for assisting regeneration of a particle filter of an exhaust line ( 3 ) of a diesel engine associated with, in particular: a particle filter ( 7 ); an oxidation catalytic converter ( 6 ); a common system ( 8 ) for feeding fuel to the cylinders of the engine; means ( 16 ) for adding to the fuel an additive adapted to reduce the combustion temperature of the trapped particles and propagate their combustion; and monitoring means ( 17 ) for triggering a phase of regeneration of the particle filter by combustion of the particles trapped therein during a phase of multiple injections of fuel; characterized in that the particle filter ( 7 ) is impregnated with a catalyst for oxidizing the hydrocarbons and CO present in the exhaust gases flowing through said particle filter.
