Abstract

A method to control the temperature of the exhaust gases of a supercharged internal combustion engine, the method comprising: determining the minimum air/fuel ratio of the exhaust gases downstream of the exhaust manifold as a function of the flow rate of air that is not involved in the combustion taking place inside the cylinders and flows directly from the intake manifold into the exhaust pipe; detecting an air/fuel ratio of the exhaust gases downstream of the exhaust manifold by means of a sensor; and controlling the supercharged internal combustion engine as a function of the comparison between the air/fuel ratio of the exhaust gases detected by the sensor and/or the minimum air/fuel ratio of the exhaust gases with a number of threshold values.
