ABSTRACT:
A method of controlling fuel supplied to an engine comprises the steps of computing the quantity of air taken into the engine on the basis of the output from an air flow rate sensor, integrating the quantity of intake air computed in the first step, determining the level for setting the period of generation of a fuel-quantity control pulse signal from a pulse generating circuit on the basis of the output from an exhaust gas sensor, and generating pulses of predetermined pulse width from the pulse generating circuit when a predetermined relation is attained between the level determined in the third step and the result of integration in the second step.
