  "textContent": "Problem to be Solved: In an international combustion engine in which fuel injection valves are arranged upstream from and downstream from the throttle valve respectively, the response of the accelerated increase in quantity and correction will be improved. Solution: The total injection quantity determination unit(101) determines a total quantity (Qtotal) of fuel to be injected from each fuel injection valve (8a, 8b) on the upstream and downstream sides. The injection rate determination unit(102)determines an injection rate (Rupper) of the upstream injection valve (8a). The correction factor calculation unit(103) calculates a total correction factor (Ktotal). The injection quantity correction unit (104) includes an accelerated increase in quantity and correction unit (1041), and during acceleration, increases and corrects only injection quantity of the downstream injection valve (8b) for acceleration. The inj ection quantity determination unit (105) determines injection quantity (Qupper) of the upstream injection valve (8a) on the basis of the injection rate(Rupper) and the total injection quantity (Qtotal), and determines injection quantity (Qlower) of the downstream injection valve (8b) on the basis of the upstream injection quantity (Qupper) and the total injection quantity (Qtotal).",
