Abstract
A method and apparatus for controlling fuel injection in an engine is described. The apparatus comprises at least one fuel injector which is connected in an injector drive circuit powered by a power source. The method comprises determining an injection event sequence of the at least one fuel injector based on at least one engine operating parameter, determining a magnitude of a load parameter of the power source, comparing the magnitude to a predetermined threshold level for the load parameter, and determining a modified injection event sequence in the event that the magnitude is substantially equal to or greater than the predetermined threshold level.
