The calculation of an adjustment value, which is determined by the concentration of oxygen in the exhaust gas, the opening of a throttle valve provided in an intake air passage to the engine, the engine temperature, etc., is started every time a predetermined number of repeatedly produced start signals, the repetition rate of which corresponds to the rotational speed of the crankshaft, occur. A basic value for fuel supply, tp K q/n, is calculated from the engine operating parameters; the amount of flow of intake air into the engine, Q the rotational speed of the crankshaft, n, and a constant k, and adjusted according to the adjustment value to obtain a control output signal, in the vicinity of the next start signal after said predetermined number.
