Abstract
Means for improving the fuel economy and hence efficiency of an internal combustion engine having electronic fuel injection where the amount of fuel delivered to the engine is proportional to the width and frequency of injector pulses. The engine is operated at constant speed and a nominal pulse width is established according to ambient conditions. The pulse width is varied, either increasingly or decreasingly, and the width is measured and stored at one point in time and compared with the width at a later time. If the comparison shows the width at a later time to be narrower than the stored value, variation is continued in the original sense. When the comparison shows that the later value of pulse width is greater than the earlier value, the sense of variation is reversed.
