Title: (EN) FUEL INJECTION CONTROL DEVICE
(JA) 燃料噴射制御装置
Abstract:
(EN) PROBLEM TO BE SOLVED: To provide a fuel injection control device preventing misfire.

SOLUTION: In the fuel injection control device provided with a target injection quantity determination means 3 determining target injection quantity of each injection to supply fuel of quantity to be supplied to a corresponding cylinder during one combustion cycle by a plurality of times of fuel injection and a fuel injection correction quantity determination means 4 determining correction quantity of one combustion cycle, the fuel injection correction quantity determination means 4 distributes the correction quantity to each fuel injection according to ratio of target injection quantity of each injection of the cylinder.
