摘要： A fuel supply system for an internal combustion engine of an automobile is disclosed which comprises a sensor for detecting an air flow rate in an intake passage, a detector for detecting rotation frequency of an engine, a sensor for detecting an oxygen concentration in an exhaust gas, a detector such as a throttle valve switch for detecting an acceleration or deceleration of the engine and a table of correction coefficients with the rotation frequency of the engine and the air flow rate in the intake passage as parameters. A feedback control of a fuel feed quantity is effected to achieve a theoretical valve of air-fuel ratio by an output of the oxygen concentration sensor if the correction coefficient is within a certain range but said feedback control is halted and the fuel feed quantity is corrected based on the correction coefficient if the correction coefficient is beyond said certain range. Said correction of the fuel feed quantity based on the correction coefficient is not effected at the accelerating or decelerating time when the air flow rate in the intake passage abruptly varies even if the correction coefficient is beyond said certain range.
