Abstract
A direct injection, solenoid fuel injector includes at least one current sensing function capable of detecting a current draw of the solenoid and a controller function. The controller is capable of determining a fully open time of the direct fuel injector solenoid based on the application of a slope inflection filter and a slope discrimination filter to a derivative of the current draw.
