ABSTRACT:
A fuel injection system for internal combustion engines injects fuel simultaneously into cylinders at a controllable number of occurences of fuel injection. The fuel injection system includes a frequency divider for frequency-dividing a signal indicative of rpm of the engine, a gate means for selectively supplying an output from the frequency-divided signal to solenoid-operated fuel injection valves, and a comparator for controlling the gate means to feed the output from the frequency-divider to the fuel injection valves when a signal indicative of an engine load exceeds a reference value upon comparison, that is, when the engine operates under heavier loads.
