ABSTRACT:
A fuel injection control system for an internal combustion engine has at least one unit injector for injecting fuel into each cylinder, and an actuator provided for each of the at least one unit injector for varying the stroke of a plunger of the each unit injector. When a rise ratio of rotational speed of the engine calculated exceeds a predetermined value, the actuator is shifted to a predetermined position, thereby preventing an abnormal rise in the rotational speed of the engine. Similarly, when a no-load condition of the engine is detected, the actuator is shifted to a predetermined position.
