ABSTRACT:
A fuel supply control apparatus for an internal combustion engine according to the present invention relates to an apparatus, in which the air intake quantity for the internal combustion engine is detected by an air flow sensor and a quantity of a fuel to be supplied to the internal combustion engine is controlled on the basis of an output from said air flow sensor, provided with the air flow sensor and a crank angle sensor for detecting a crank angle of the internal combustion engine and capable of reasonably controlling an air fuel ratio of the internal combustion engine even in the case, where a throttle valve is almost completely opened, by detecting the air intake quantity in a range of a predetermined crank angle interval, determining a resulting value which is proportional to the air intake quantity per one intake stroke of the internal combustion engine, on the basis of the detected value, limiting the resulting value by a predetermined value corrected by parameters of the internal combustion engine, and controlling the quantity of a fuel to be supplied to the internal combustion engine on the basis of the limited resulting value.
