ABSTRACT:
The invention relates to an injection control device for an internal combustion engine, in which a programmed microprocessor calculates the open time of a plurality of electrically operated injectors as a function of prechosen engine parameters, and determines the activation of said injectors into their open state and their deactivation into their closed state with the aid of a single timer, which counts-out the calculated open time. If a second injector is opened while a first injector is still delivering the fuel, the microprocessor calculates the difference between the open time of the second injector and the remaining open time of the first injector, so as to be able to count-out the open time of the two injectors on the single timer.
