Abstract
Method for controlling a fuel injector with a solenoid actuating a needle opening the injector and a spring returning the needle to the closed position. A controller, powering the solenoid, provides a first potential connected to a first transistor's drain, the source of the first transistor connected to the first diode's anode, the cathode of the first diode connected to a second diode's cathode, to a first connector of the solenoid and to the source of a second transistor. The drain of a second transistor is connected to a second potential, the second diode's anode being connected to ground, the second potential being connected to ground via a capacitance and to the cathode of a third diode, the third diode's anode being connected to a second connector of the solenoid and to the drain of a third transistor, the source of the third transistor being connected to ground.
