The method comprises, after the end of the normal combustion of the mixture in the combustion chamber of the engine, establishing a post-combustion by maintaining a series of high-tension sparks during a long period and introducing turbulent additional air in the vicinity of said sparks so as to form a plasma which is propagated in said residual mixture. The plasma is propagated in the cylinder from a plurality of points, that is to say partly from a point near to the spark and partly from at least another point of the combustion chamber.
