Method for controlling the temperature of the exhaust gas in an internal combustion engine

摘要

Method of controlling the temperature (T exhgas ) of the exhaust gas in an internal combustion engine (1); said method of control consisting of: determining the air/fuel ratio (») of the exhaust gas; determining the speed (É mot ) of rotation of the internal combustion engine (1); and estimating the effective temperature (T exhgas ) of the exhaust gas as a function of the air/fuel ratio (») of the exhaust gas and as a function of the speed (É mot ) of rotation of the internal combustion engine (1).
