Abstract
The invention relates to a method for controlling a piezoelectric actuator of a fuel injector, comprising the steps of: applying a nominal electric command charge (Qc1) to the piezoelectric actuator, according to a nominal current (lcc1), so as to open the valve means of the injector; and on top of the nominal command charge (Qc1), after the application of same and before the step consisting in ordering the closing of the injector, applying at least one electric polarisation charge (Qp1) to the piezoelectric actuator, in addition to the nominal command charge (Qc1), so as to polarise the piezoelectric actuator during an opening phase of the injector; said method also comprising a preliminary step of increasing the value of the polarisation charge current (Icp1) applied to the piezoelectric actuator to a value higher than that of the nominal current (Icc1) of the nominal command charge (Qc1).
