Abstract
An individual difference index is obtained based on the slope of variation ratios between a plurality of actual injection quantity and a target injection quantity. The individual difference index is stored as a learning value. An individual difference correction of the fuel injector is conducted based on the individual difference index. By using the individual difference index, a shot-dispersion is removed and individual-difference correction of the fuel injector can be conducted.
