System and method for adjusting on-time calibration of a fuel injector in internal combustion engine
Patent number: 9850872Abstract: 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.
