ABSTRACT:
A fuel control apparatus for an internal combustion engine comprises an crank angle sensor producing a crank angle signal at a predetermined crank angle in the engine, an intake air quantity detector for detecting the quantity of intake air sucked in the engine, an injector for injecting fuel to an engine cylinder, and a control means for actuating the injector at a driving time in response to the quantity of intake air and at a timing determined by the crank angle signal, wherein a period calculating means calculates the next period on the basis of the previous period and the present period in the crank angle signal and an injection-initiating time control means controls a time to actuate the injector in accordance with the next period of the crank angle signal.
