Abstract
The invention concerns a method which consists in using an injector supplied with fuel whereof the pressure (Pcarb) 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 (T1). The invention is characterized in that the duration (T1) of the current peak in an increasing function of the pressure (Pcarb) of the fuel. Thus, the dynamics of the injector is increased.
