REGENERATION SYSTEM FOR EXHAUST GAS PARTICLE FILTER SYSTEMS

摘要

A process for the regeneration of engine emission particulates collected in particulate filter traps associated with each of the engine cylinders, or with groups of such cylinders, includes the selective elevation of the emission temperature of at least one of the cylinders or groups to the extent required for regeneration, by oxidation, of the filter trap or traps associated therewith, by supplying engine fuel to such cylinder or cylinders in a predtermined amount to produce the elevated emission temperature, and supplying the remaining of the cylinders with amounts of engine fuel less than such predetermined amount as required to sustain the given engine power output.
