Abstract
A fuel injection system includes a fuel injector, the fuel injector having an injection control valve, a solenoid that, when energized, is configured to modify a position of the injection control valve, and a controller. The controller is configured to generate a command for energizing the solenoid, identify variability in one or more injection events, and based on the identified variability, increase an amount of energy supplied to the solenoid.
