摘要： An engine control apparatus for controlling the quantity of fuel injected into the engine is equipped with an intake air flow rate measuring device for detecting the operating state of the engine. This measuring device has a heat sensitive element, which is located in the intake pipe, and outputs a pulse signal having a pulse width T corresponding to the intake fuel amount. Engine control apparatus has a plurality of map memory means in which a plurality of functions f.sub.1 (N), f.sub.2 (N), f.sub.3 (N), which express the polynomial approximation ##EQU1## for expressing the air flow rate G/N per engine revolution, are stored as the parameters of the number of engine rotations N. These functions are read out from the maps and, based on the number of engine rotations N, the fuel injection amount corresponding to the pulse width T of the air flow rate is calculated.

摘要： In an electronic digital control system for engine, a throttle position is sensed at predetermined time intervals to detect a variation thereof from the previous time to the present time, and, after modifying the detected variation by a correction coefficient related to a cooling water temperature to obtain the modified variation, the previous value of a fuel injection amount correction factor computed at the time of previous computation is added to the value of the modified variation to compute the sum. Then, a predetermined subtraction constant is subtracted from the sum to compute the difference therebetween, thereby obtaining the new data of the fuel injection amount correction factor, and this new factor is used to correct the basic fuel amount computed separately on the basis of the operating condition of the engine.
