ABSTRACT:
The amount of fuel supplied to an internal combustion engine is determined by controlling the opening interval of each fuel injection valve by correcting a standard interval obtained from the amount of intake air and engine speed by first to third correction factors. The first correction factor is dependent on coolant and intake air temperatures, while the second correction factor is dependent on a gas sensor output indicative of the air/fuel ratio of the mixture supplied to the engine. A plurality of third correction factors is provided for different amounts of intake air. Some of the third correction factors corresponding to intake air amounts at which the engine has been operated, are corrected in accordance with the value of the second correction factor. The state of correction is detected and when third correction factor has been corrected in the same direction by a relatively large amount, all of the third correction factors, which have been stored in a memory, are uniformly modified to renew the stored data.
