Abstract:
A method for controlling fuel injection timing in an engine operable in a selected one of a plurality of engine notch positions, the method comprising the steps of:determining whether the engine is in a steady state mode of operation;determining whether a fuel value indicative of a fuel quantity to be delivered to the engine is within a predetermined fuel value range for the selected one of the plurality of notches;setting a predetermined fuel injection timing value that uniquely provides a one-to-one correspondence to the selected one of the plurality of notches upon verification that the fuel value is within the predetermined fuel value range; andin the event the fuel value is outside the predetermined fuel value range and/or the engine is not in steady state, setting a fuel injection value from a band of timing values generally extending beyond the selected one of the plurality of notches.
