Abstract

See full text

The disclosure provides a system and method for determining an amount of fuel injected or delivered by a single fuel injector in an internal combustion engine by generating one fuel injection event after the engine has stopped operating. The fuel delivered is statistically analyzed in comparison with a commanded fuel delivery amounts to determine the suitability of fuel injector on-time calibration for the analyzed fuel injector. If the fuel delivered deviates from the commanded amount of fuel delivery by a predetermined value, the fuel injector on-time calibration for the analyzed fuel injector is changed.
