<p>The subject of the present invention is a method for determining if an injector (10) is in a blocked state, the injector comprising a coil of resistance R and of inductance L, passed through by a power supply current of maximum intensity (Imax), and powered by a voltage E, said method consists in: • controlling the opening of the injector, • measuring the intensity I passing through a measurement resistance r as a function of time t, • determining a necessary duration ? to reach a predetermined intensity value (Ipred), lower than the maximum intensity (Imax), • computing the inductance L as a function of the necessary duration, • if L ? Lth, then the injector is blocked in the closed position, otherwise • if L < Lth, the injector is blocked in the open position, with Lth being a threshold value of the inductance.</p> |
