Abstract
A method for controlling an internal combustion engine that is to be operated either by petrol or alcohol or by a variable proportion of the two fuels and that includes an electronic control unit that can drive the engine, an admission line, and an exhaust line that includes a richness probe. The method determines the richness of the carbide mixture entering into the combustion cylinders, and increases the duration of the injection by intervals according to the richness of the carbide mixture.
