METHOD FOR CONTROLLING A SYSTEM FOR THE TREATMENT OF THE EXHAUST GASES OF AN INTERNAL COMBUSTION ENGINE

摘要

The invention relates to a method for controlling a system for the treatment of the exhaust gases present in an exhaust line of an internal combustion engine, said treatment involving using a gauge-pump module to inject a reducing agent into the exhaust line, this injection being governed by a calculation module capable of determining the amount of suitable reducing agent to inject, characterized in that operation of the control module is subordinated to a supervisor that allows injection to take place only if the ambient pressure is above a given pressure, the external temperature is in a given temperature range, and the gauge-pump module is deemed operational.
