Abstract
Provided is a device for controlling a fuel injection device capable of suppressing deterioration of exhaust performance while ensuring driving performance when acceleration of a vehicle is requested during an intake stroke. Therefore, when the acceleration of a vehicle is requested during an intake stroke in one combustion cycle, an engine control unitestimates an increase (acceleration intake air amount Qad) of the amount of air taken in a combustion chamberof an internal combustion engineassociated with the acceleration of the vehicle after the acceleration of the vehicle is requested in one combustion cycle based on a lift amount of an intake valve. The engine control unitcontrols a fuel injection valveso as to increase a fuel injection amount in one combustion cycle according to the acceleration intake air amount Qad.
