Means for correcting the quantity of fuel injected into an engine cylinder so as to regulate the number of rotations of each cylinder while reflecting the rotation unevenness unique to the engine cylinder. A common-rail diesel engine (1) is an engine (2) having injectors (3) whose valve open timings can be individually controlled, an individual reference number-of-rotations output unit (30) for outputting the individual reference number-of-rotations Nstdi of the cylinder of each of injectors (3) corresponding to the fuel injection by the injector (3), engine number-of-rotations sensors (6) for detecting the individual actual number-of-rotations Ni of the cylinder of each injector (3) corresponding to the fuel injection by the injector (3), and correction amount calculating unit (50) for calculating the correction amount of the quantity of fuel injected from the injector (3) of the cylinder from the difference between the individual reference number-of-rotations Nstdi stored by the individual reference number-of-rotations output unit (30) and the individual actual number-of-rotations Ni calculated by the engine number-of-rotations sensor (6).
