| Summary: | The present invention relates to a method for controlling the amount of fuel injected into a direct-injection internal combustion engine. More especially, the invention relates to such a method employed using an injector supplied with fuel under pressure, the opening of said injector being triggered electromagnetically by supplying an electric coil that forms part of the injector with a current spike of predetermined duration.
The invention concerns a method which consists in using an injector supplied with fuel whereof the pressure (P) is an increasing function of the amount of fuel (Q) to be injected, the opening of the injector being electromagnetically triggered by energizing the electric coil integral with the injector with a current peak of predetermined duration (T). The invention is characterized in that the duration (T) of the current peak in an increasing function of the pressure (P) of the fuel. Thus, the dynamics of the injector is increased. |
