    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.

    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.

    Abstract: An electronic control circuit for the fuel injectors of an internal combustion engine is disclosed, which comprises a circuitry for detecting certain indicative parameters of the engine working conditions and of the power requirements requested by the engine operator, electronic circuitry means being provided for generating pulse train signals to be compared with the signals corresponding to the detected parameters and circuitry means for effecting a comparison with one of a series of preselected patterns of injector feed (intermittency of feed and duration of each feeding burst) thus enabling a control circuit to enter action so as to adapt the operation of the injectors to the preselected pattern. The operator has thus a comparatively wide choice among a number of typical engine operative situations. Consistent fuel savings can thus be obtained along with a more regular engine run.
