ABSTRACT:
An electric control for a fuel injector develops a commanded boost signal that is superimposed on a fuel injection pulse waveform. Variable operating parameters, such as engine speed, fuel injection quantity, engine coolant temperature, and engine air intake temperature are monitored and may diminish the duration of the commanded boost signal under certain conditions to avoid overheating electric circuit elements in the control through which electric power is delivered to the fuel injector.
