PURPOSE: To high accurately study control a fuel injection amount, by controlling the section of an engine operative area, which stores a reference corrective value for correcting the air-fuel ratio controlling-basic control value in accordance with an engine operative condition, to correspond to the fuel injection amount of a fuel injection valve.
CONSTITUTION: The first memory means 26, which stores the basic control value for controlling air-fuel ratio of a mixture in an address corresponding to an engine operative condition, and the second memory means 25, which stores a reference corrective value for correcting said basic control value in an address corresponding to a fuel injection amount, are provided. Then on the basis of the output of an air-fuel ratio sensor 17, an air-fuel ratio corrective value arithmetic means 29 calculates an air-fuel ratio corrective value, and on the basis of this corrective value, a reference corrective value arithmetic means 30 calculates the reference corrective value further to be stored in the memory means 25. And then on the basis of said basic control value, reference corrective value and the air-fuel ratio corrective value, a fuel injection valve 8 is controlled by a control means 31 so that air-fuel ratio may become the preset air-fuel ratio.
