Abstract:
Method for piloting electromagnetic actuators (6) for the control of the valves of an engine; each electromagnetic actuator (6) comprising at least one respective electromagnet (7), which is piloted by a common piloting device (5) by means of the supply of an electric current wave (O) which has at least one control portion in which the intensity of the electric current (i) varies rapidly and a maintenance portion in which the intensity of the electric current (i) remains substantially constant; the method consisting of supplying respective electric current waves (O) cyclically to the electromagnets in order to control the valves according to the drive point; the method being characterized in that there is variation at the control portion of each electric current wave (O) of the value of the intensity of the electric current (i) supplied during the portions of maintenance of the other electric current waves (O) in order to limit the variation of the quantity of electric charge distributed overall by the piloting device (5).
