ABSTRACT:
A fuel injection system for a direct fuel injection engine includes an injection mode module. The injection mode module selects a fuel injection mode to be one of a single injection mode and a dual injection mode. A fuel injection command module transitions between the single and dual injection modes by varying the timing of fuel injection events relative to a crankshaft position.
