Abstract:
An internal combustion engine comprising:a processor-based engine control system; and a fueling system that fuels the engine under control of the engine control system; wherein the control system processes data to develop desired fueling data representing a desired amount of fuel for fueling the engine, modifies the desired fueling data by a multiplier during cranking, starting, and initial running phases of the engine, causes the fueling system to fuel the engine according to the modified desired fueling data during the cranking, starting, and initial running phases of the engine, and thereafter modifies he multiplier by a multiplier adder and causes the fueling system to fuel the engine according to the modified desired fueling data as further modified by the multiplier adder, in which the control system causes the value of t e multiplier adder to be a function of the value of an average of desired fueling data taken over a time interval that includes time prior to the initial running phase of the engine.
