A process for controlling supplying fuel for an internal combustion engine, employed when the engine is started, including: measuring at least one characteristic value of an engine speed representative of a richness of a fuel/oxidant supply mixture for the engine, comparing the measured characteristic value with a reference value so as to determine a value of the difference between these two values, and controlling the supply unit using a control signal emitted by a control unit () and dependent on the difference value. The process also includes an updating step of producing an updated reference value (), when an aging threshold of the engine is passed.

Method of adapting an internal combustion engine to the quality of the fuel used

A method of controlling the startup of an engine using a sensor having a reference index, commanding the rotation of the crankshaft, detecting the rotation of the crankshaft, selecting a group of cylinders for which the reference index is detected less than a half-turn of the crankshaft before the piston reaches the top dead center, before the inlet valves of the selected group of cylinders closes, commanding the injectors of the selected group of cylinders, detecting the reference index, and commanding the ignition element.
