PROBLEM TO BE SOLVED: To abate the burden of a control process to be imposed on a controller, and simultaneously to promote a reduction in manhours for adjusting it. SOLUTION: A first correctionΔθ1 or a correction for a first command valueθ1 to control a pilot injection quantity performs a linear interpolation between the value 'Δθ1H' corresponding to 'NPH' and the value 'Δθ1L' corresponding to the 'NPL', whereby the first correctionΔθ1 corresponding to the engine speed is calculated. Likewise, both second and third correctionsΔθ2 andΔθ3 or each correction of both second and third command values for controlling a main injection quantity are calculated as well. Thus, since when interpolation calculation on the basis of engine speed is carried out only once, respective correctionsΔθ1 toΔθ3 are calculable, so that any burden on a control process to be imposed on a fuel injection controller is reducble. In addition, it is good enough that the correction exists one by one at each command value and engine speed, so that adjusting manhour for the fuel injection controller can be lessened.
