Abstract
A fuel injector is provided. The fuel injector includes a sleeve having a first end proximate an outlet; a piston slidingly received in the sleeve, the piston having a first end proximate the outlet; a pumping chamber at least partially defined by the sleeve between the first end of the piston and the outlet; and a normally-open inlet valve through which fuel passes to enter the pumping chamber.

A control system for a fuel injector, the control system comprising:
- a circuit configured to measure a current through a coil in the fuel injector;
- and
- processing electronics configured to:
- receive the measured current from the circuit;
- and
- determine at least one of a velocity or a position of the coil through a magnetic field by correlating the measured current to the velocity of the coil.
