JPS6328212B

A fuel supply control method for electronically controlling the fuel supply to an internal combustion engine equipped with a supercharger. Pressure in the intake passage downstream of a throttle valve arranged therein is detected by first and second pressure sensor means, whereas a plurality of predetermined values of basic fuel quantity are stored in each of first and second storage means corresponding, respectively, to the first and second pressure sensor means, which are functions of the intake passage pressure and the engine rpm. When the value of an output signal from one of the first and second pressure sensor means is smaller than a predetermined value, a stored value of basic fuel quantity corresponding to the value of an output signal from the first pressure sensor means and the engine rpm is read from the first storage means, and when the value of the output signal from the above one pressure sensor means is larger than the above predetermined value, a stored value of basic fuel quantity corresponding to the value of an output signal from the second pressure sensor means is read from the second storage means. A quantity of fuel corresponding to the stored value thus read is supplied to the engine.
