Kraftstoffeinspritzventil , mit einer Mehrstufenstrom-Magnetspule
摘要
<p>A fuel injector includes first and second valves and a solenoid including a solenoid coil and an armature assembly wherein the first and second valves are coupled to the armature assembly. A solenoid drive circuit is coupled to the solenoid coil and delivers a first current waveform portion to the solenoid coil at a first time to cause the armature assembly to operate the first valve without operating the second valve. A second current waveform portion different than the first current waveform portion is applied to the solenoid coil at a second time later than the first time to operate the second valve. <IMAGE></p>
