METHOD FOR MANAGING THE OPERATION OF AT LEAST ONE CATALYTIC CONVERTER FOR INTERNAL COMBUSTION ENGINE

摘要

The invention relates to a method for managing the operation of at least one catalytic converter (7) fitted in the exhaust line (3) of an internal combustion engine (1), said catalytic converter being bled off based on predetermined criteria such as the moment when a threshold value is reached, wherein said method is characterised in that it comprises at least the following steps: estimating the dilution during rolling (100); comparing the estimated dilution with a predetermined critical threshold (110); modifying the occurrences of the sulphur and nitrogen oxide bleedings from the catalytic converter (7) when the estimated dilution exceeds the threshold (120, 130). The invention also relates to a system for managing the operation of at least one catalytic converter (7) fitted in the exhaust line (3) using the method of the present invention.
