Abstract
A method of fuel injection comprises an initial step of providing an electronically-controlled hydraulically-actuated fuel injector. An on-time for the fuel injector that corresponds to a desired amount of fuel is determined. The fuel injector is activated for that on-time. Next, the actual amount of fuel injected by the fuel injector is estimated. The actual amount of fuel is compared to the desired amount of fuel. If the actual amount of fuel is substantially more than the desired amount of fuel, the on-time for a subsequent injection event is adjusted.
