ABSTRACT:
A control method of supplying an internal combustion engine with required quantities of fuel appropriate to operating conditions of the engine, in synchronism with pulses of a control signal generated at predetermined crank angle positions of the engine. When the engine is operating in a predetermined accelerating condition, a correction variable for increasing the fuel supply quantity for supply to the engine at acceleration is determined as a function of the number of pulses of the above control signal generated after the predetermined accelerating condition has been detected for the first time, as well as of the rate of change of the value of a predetermined operating parameter indicative of the engine load which is detected in synchronism with a predetermined sampling signal, to thereby set a quantity of fuel for supply to the engine at acceleration. Preferably, values of the correction variable are read from a plurality of tables in which are set different predetermined values as functions of the rate of change of the value of the predetermined operating parameter, preferably the rate of change of throttle valve opening, and which are selected in response to the number of pulses of the above control signal successively generated from the time of the first detection of the predetermined accelerating condition of the engine.
