A system for controlling the displacement of a spool in a spool valve of a fuel injector. One or more coils may be employed to move the spool between closed and open positions in the fuel injector. The shape of the current waveform used to generate a magnetic field in one or more coils for displacing the spool may vary depending on engine operating conditions. Moreover, the shape of the current waveform applied to coils in the fuel injector may be different for engine operating conditions. Such differences in waveform shape may at least assist, in real time, with the engine obtaining improved engine emissions and/or otherwise obtaining fuel injection goals. |
