ABSTRACT:
An electronically-controlled fuel injection system having a synchronous counter which receives main injection time data corresponding to an amount of fuel to be injected synchronously to engine revolutions, and an asynchronous counter which receives increment injection time data corresponding to an amount of fuel to be injected at a selected time interval asynchronously to the engine revolutions, wherein the synchronous counter is operated for a period of time equal to the main injection time data upon receiving a synchronous signal which is generated synchronously to the engine revolutions, while the asynchronous counter is operated for a period of time equal to the increment injection time data upon receiving an asynchronous signal which is generated at the selected time interval, so as to open a fuel injection valve by pulses which are output from the respective counters during the operations thereof. The electronically-controlled fuel injection system is provided with timers which ad a predetermined period of time after the end of the operation of each of said respective counters, and delay means operating when, during the operation of one of the two counters, a synchronous signal or an asynchronous signal for operating the other counter has been generated to delay the input of the signal to the other counter until the timekeeping of the timer ends.
