摘要： The invention relates to a method for controlling an internal combustion engine (1) which is to be operated either by petrol or alcohol or by a variable proportion of the two fuels, and comprises an electronic control unit (5) that can drive the engine (1), an admission line (3), and an exhaust line (4) provided with a richness probe (8). The inventive method is characterised in that it comprises at least one step wherein the richness of the carbide mixture entering into the combustion cylinders is determined, and a step (34) wherein the duration of the injection is increased by intervals according to the richness of the carbide mixture.
