Title: Method and apparatus for dynamic trimming of fuel system

Abstract: With reference to the drawings and in operation, the present invention is adapted to provide a method and apparatus for dynamically controlling the injection timing of a fuel injector connected to a fuel system located within an engine. The method includes the steps of establishing a desired injection timing of the injector 104 and determining an fuel injection command delivery time in response to the desired injection timing, and responsively delivering the fuel injection command. The actual injection timing is determined, and then the injection command delivery time is modified in response to comparing the actual and the desired injection timing. Comparing the actual and desired injection timing provides for closed loop control of the injection timing of the fuel system 102.
