METHOD AND DEVICE FOR MONITORING THE REGENERATION OF A POLLUTION-REMOVAL SYSTEM

摘要

A method for monitoring regeneration of a pollution-removal system, relying on introduction of fuel into exhaust gases by delayed injections of fuel into certain combustion chambers of an engine and/or direct injections into an exhaust system upstream of a filter depending on an inlet temperature of the system. Introduced fuel delivery is assigned to direct injections into the exhaust system and/or to delayed injections into the combustion chamber according to the value of the wall temperature of the exhaust system.
