System for the regeneration of a particulate filter trap

摘要

A system for the regeneration, by oxidation, of the particulates deposited in a particulate filter trap of an internal cumbustion engine provided for purifying the engine exhaust gas, in which the thickness of the particulates deposited in a given area in the trap is determined relative to a predetermined thickness in excess of which the filter trap will operate inefficiently, and the excess thickness being reduced by regeneration.
