PROBLEM TO BE SOLVED: To provide a fuel injection control device of an internal combustion engine capable of reducing vibration caused in the internal combustion engine even in the multiple cylinder internal combustion engine in which intervals between explosion strokes are not equal to each other. SOLUTION: This fuel injection control device of the internal combustion engine controlling a fuel amount injected into the multiple cylinder internal combustion engine in which the explosion strokes occur at non-equal intervals comprises a crank angular velocity detection means detecting the angular velocity of a crankshaft and a control means controlling the fuel amount injected so that the ratio of the maximum valueω1max of the angular velocity of the crankshaft detected by the crank angular velocity detection means in a period in which the intervals of the continuously occurring non-equal intervals are short to the maximum valueω2max of the angular velocity of the crankshaft in a period in which the intervals are long becomes a specified value smaller than 1. The fuel amount injected is controlled so that a variation in the crankshaft angular velocity becomes optimum to reduce vibration. COPYRIGHT: (C)2005,JPO&NCIPI
