ABSTRACT:
The present invention relates to an engine control device adapted to determine a basic fuel feed rate (Tp) in response to signals from a suction air flow rate sensor (20) and an air-fuel ratio sensor (20), and thereafter a fuel feed rate (Ti). According to the present invention, suction air flow rates (Q.sub.An-1, Q.sub.An-2) are calculated first on the basis of the last and the next to last fuel feed rates (Tin-1, Tin-2). The coefficients (A, B) required to correct the properties of the suction air flow rate sensor (20) are computed on the basis of these suction air flow rates. In the present invention, a fuel feed rate is determined finally on the basis of these coefficients.
