METHOD AND DEVICE FOR CONTROLLING THE REGENERATION OF A DEPOLLUTION SYSTEM

摘要

A method of controlling the regeneration of a pollution control system (8), based on the introduction of fuel into the exhaust gas by delayed fuel injection into certain combustion chambers of the engine and / or by direct injection into the engine exhaust line upstream of the filter, as a function of the inlet temperature of the system, characterized in that the fuel flow (Qred) introduced is assigned to direct injection into the exhaust line and / or to the injections in the combustion chambers according to the value of the wall temperature (Tparoi) of the exhaust line.
