装置。A first cylinder with large diameter injection holes for each cylinder 3 of the engine.
A fuel injection valve 11 and a second fuel injection valve 12 having a small diameter injection hole
A fuel injection pump 1 is attached to the first fuel injection valve 11 and the second fuel injection valve 12 so as to be able to operate independently or simultaneously. During no-load or low-speed operation of the engine, fuel oil is fed only to the second fuel injection valve 12 side, and in other operating ranges, fuel oil is fed to the first fuel injection valve 11 and the second fuel injection valve 12 simultaneously or to the second fuel injection valve 12 side. A fuel injection device for an internal combustion engine, characterized in that the fuel injection device is connected through an appropriate injection valve switching device 2 which acts to supply fuel only to one fuel injection valve 11.
