Abstract:
A method for controlling an electromagnetically-activated fuel injector includes, when a plurality of fuel injection events are close-spaced during an engine cycle, monitoring a respective desired injected fuel mass for each of the plurality of fuel injection events. A desired current wave form is selected from a plurality of current waveforms whereat each respective desired injected fuel mass is achieved based on at least one of the fuel injection events. The fuel injector is controlled using the desired current waveform.
