【実用新案登録請求の範囲】[Scope of utility model registration request] 燃料噴射系に燃料噴射管を有する燃料噴射装置において
、上記燃料噴射管は断面形状を燃料噴射ポンプ側の円形
状より燃料噴射弁のノズル側の楕円形状に徐々に変形さ
せると共に上記燃料噴射ポンプ側から上記ノズル側へ近
づくにつれて断面積を小さくしたことを特徴とする燃料
噴射装置。In a fuel injection device having a fuel injection pipe in the fuel injection system, the fuel injection pipe gradually changes its cross-sectional shape from a circular shape on the fuel injection pump side to an elliptical shape on the nozzle side of the fuel injection valve, and also has a cross-sectional shape on the fuel injection pump side. A fuel injection device characterized in that the cross-sectional area becomes smaller as it approaches the nozzle side.
