ABSTRACT:
A control device for the fuel feed actuators of an internal combustion engine comprises a detector for detecting a first engine parameter (e.g. engine RPM), another detector for detecting another engine parameter (e.g. throttle angle), a further detector for detecting the operative condition of the engine (e.g. the temperature of the coolant), a pulse generator connected to the engine shaft, another pulse generator connected to an auxiliary shaft, a processor (CPU), a read only memory unit (ROM), a random access memory unit (RAM), two timers, the processor unit (CPU) performing a sequence of programmed steps in order to select which of the electric fuel injectors must be actuated, at what instant of time, for what time period and with what quantity of fuel each time.
