    • A fuel injection system injects fuel to an internal combustion engine having a plurality of cylinders by means of a single fuel injector. For a four cylinder engine in which the suction stroke is repeated in the order of first, third, fourth and second cylinders, the single fuel injector responds to a control signal from a control system to initiate a single-shot injection upon the suction strokes of the first and the fourth cylinders. The fuel injection initiating timing as well as the injecting duration are arithmetically determined by a CPU a and ROM of the control system on the basis of the signals representative of operating conditions of the engine available from a hot-wire sensor, a crank angle detector, a temperature sensor, an O.sub.2 -sensor and supplied to the single fuel injector. The cylinders to which the fuel is to be injected are changed over from the first and fourth cylinders to the second and the third cylinders by the CPU in response to the signal output from the O.sub.2 -sensor.
