System for assisting the regeneration of aparticle filter integrated into an exhaust line of a motor vehicle diesel engine

摘要

This system is characterized in that the engine (1) is linked to various members and to means (17) for checking the operation of these various members in order to control the operation of the engine, these means also being designed to trigger a regeneration phase of the particle filter by combustion of the particles trapped in the latter, at the same time initiating a phase of multiple injections of fuel into the cylinders of the engine during their expansion phase, and in that the checking means (17) are designed to control closing of the means (4) for recycling the exhaust gases at the inlet of the engine during a regeneration phase of the particle filter, so as to make it possible to check the composition of the gases at the inlet of the particle filter (7) and isotorque operation of the engine.
