ABSTRACT:
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.
