  • Method for determining the closing time of an electromagnetic fuel injector
    Patent number: 8571821
    Abstract: A method for determining the closing time of an electromagnetic fuel injector including the steps of applying at a starting time of the injection a positive voltage to the coil of the electromagnetic actuator in order to circulate through the coil an electric current which causes the opening of an injection valve; applying at an ending time of the injection a negative voltage to the coil in order to annul the electric current flowing through the coil; detecting the trend over time of the voltage across the coil after the annulment of the electric current flowing through the coil; identifying a perturbation of the voltage across the coil; and recognizing the closing time of the injector that coincides with the time of the perturbation of the voltage.
