Abstract
A fuel control system for an engine has a fuel injector which injects fuel into an intake passage of the engine. An airflow meter detects the amount of intake air of the engine. A controller controls the amount of fuel to be injected from the fuel injection means on the basis of a dulled value by dulling a present value of the output of the airflow meter so that the preceding value of the output of the airflow meter is reflected in the dulled value in a predetermined proportion. The degree of reflection of the preceding value of the output of the airflow meter in the dulled value is reduced when the relation between the value of the output of the airflow meter and the dulled value is inverted.
