ABSTRACT:
There is provided a fuel injection system for an internal combustion engine comprising fuel injection means provided for each of the cylinders of the engine, a main computing circuit for determining the timing of the injection and the duration of the injection in accordance with the charging and discharging of electric energy corresponding to the number of revolutions of the engine and the quantity of air drawn thereinto and generating pulse signals, a distribution circuit for distributing the pulse signals to the fuel injection means, and a reference signal generating circuit for generating an electric signal to complete the charging of electric energy in the main computing circuit within 720.degree./(2 .times. the number of cylinders) of crank travel, whereby the construction of the system is simplified since there is no need to modify in any way the conventional fuel injection valves or the like and provide the main computing circuit for each of the cylinders, and moreover fuel can be separately injected into each cylinder in turn in accordance with the firing order of the engine.
