ートに指向させて燃料噴射弁を設けてなる内燃機
関において、前記燃料噴射弁を燃料噴霧角可変構
造とし、燃料噴射弁の燃料噴霧角を前記開閉弁の
開弁時には大きく、閉弁時には小さくなるよう制
御する噴霧角制御手段を設けたことを特徴とする
内燃機関の燃料噴射装置。 Each cylinder has two intake ports, and one intake port is provided with an on-off valve that opens and closes according to engine operating conditions, and the central axis of fuel spray is located upstream of the on-off valve and near the confluence of the two intake ports. In an internal combustion engine, the fuel injection valve has a variable fuel spray angle structure, and the fuel spray angle of the fuel injection valve is large when the opening/closing valve is opened, and when the opening/closing valve is closed, the fuel injection valve has a variable fuel spray angle structure. 1. A fuel injection device for an internal combustion engine, comprising a spray angle control means for controlling the spray angle so that the spray angle becomes smaller when the valve is applied.
