ル機関の燃料噴射弁において、ノズルの主穴をバ
ルブリセス数の整数倍として、同各主穴を上記バ
ルブリセスを設けないピストン外周の凸部に向け
ると共に、小径の副穴を上記主穴と同心、同角に
形成するか、または上記主穴と異心または異角に
形成したことを特徴とする燃料噴射弁。 In a fuel injection valve for a diesel engine that has a valve recess at the top of the piston, each main hole of the nozzle is an integral multiple of the number of valve recesses, and each main hole is directed toward a convex part of the piston's outer periphery where the valve recess is not provided, and a small-diameter sub-hole is installed. A fuel injection valve characterized in that the fuel injection valve is formed concentrically or at the same angle as the main hole, or eccentrically or at a different angle from the main hole.
