PURPOSE:To improve drivability during acceleration, by a method wherein a moderating value of a ratio of an intake air amount to the number of revolutions, serving as a basis of a calculation value of a fuel injection amount, is changed depending upon the operating state of a supercharger. CONSTITUTION:A means 7 of computing a moderating value of a ratio Q/N of an intake air amount to the number of revolutions computes a moderating value of Q/N based on the number of revolutions and an intake air amount, detected by an intake air amount detecting means 5 and a number of revolutions detecting means 6, and the state of a supercharger 3 detected by a supercharging state detecting means 4. The value serves as a basis of calculation of a fuel injection amount, and a fuel injection control means 8 controls a fuel injecter 2 so as to obtain a fuel injection amount responding to the Q/N moderating value. This maintaines an air-fuel ratio at a specified value through the feed of an air amount optimum to an internal-combustion engine 1 in response to the operating state of the supercharger 3, and enables improvement of drivability despite of a change in the working condition of the supercharger 3.
