Abstract
A method of controlling a fuel injector assembly of an internal combustion engine includes the stop of generating a first injection pulse with an engine control module. The method also includes the step of injecting fuel into a cylinder of the engine in response to generation of the first injection pulse. The method further includes the step of detecting when fuel is injected into the cylinder and generating a control signal in response thereto. Moreover, the method includes the step of determining a time period between generation of the first injection pulse and generation of the control signal. The method also includes the step of adjusting initiation of a second injection pulse based on the time period. An apparatus for controlling a fuel injector assembly of an internal combustion engine is also disclosed.
