ABSTRACT:
In one aspect of the present invention, a method is disclosed that controls the actuating fluid pressure supplied to a hydraulically-actuated injector and the time duration over which the hydraulically-actuated injector injects fuel. The desired actuating fluid pressure and injection duration is swept across a range of values to achieve an optimum combination of values to start an engine.
