Abstract
The present invention relates to a method of controlling a spark-ignition supercharged internal-combustion engine, notably of gasoline type, comprising at least one cylinder (12) with a combustion chamber (14), at least two intake means (24, 26), at least one fuel injection means (40, 42), at least one exhaust means (28, 30) and an ignition means (52). According to the invention, the method consists in preparing a fuel mixture with a fuel/air ratio greater than or equal to 1, another fuel mixture is prepared with a fuel/air ratio below 1, the two fuel mixtures are fed into the combustion chamber so as to obtain a part (C1) of this chamber containing a fuel mixture with the fuel/air ratio greater than or equal to 1 and the remaining part (C2) of the chamber containing the fuel mixture with the fuel/air ratio below 1.
