Abstract
A device for controlling the operating state of a catalytic converter in the exhaust line of an internal combustion engine, including a mechanism for determining the temperature upstream and downstream of the converter, a mechanism for injecting fuel in the exhaust line of the engine, a mechanism for calibrating a temperature model on a measured operating temperature of the catalytic converter, and a mechanism for calculating the integral of the difference between the measured temperature and the modeled temperature downstream of the converter.
