Title
(EN) FUEL INJECTION VALVE
(FR) SOUPAPE D'INJECTION DE CARBURANT
(JA) 燃料噴射弁
Abstract
(EN)
A fuel injection valve is configured in such a manner that each of the injection holes comprises an injection hole body and a large-diameter section which is located adjacent to and downstream of the injection hole body and which constitutes the outlet of the injection hole. When each of the injection holes is projected perpendicularly onto a plane perpendicular to the axis of a valve seat, the center of the inlet of the injection hole body and the center of the outlet thereof are arranged on the plane in such a manner that the centers are arranged side by side on a radial straight line passing through the axis of the valve seat and in such a manner that the center of the outlet is farther from the axis of the valve seat than the center of the inlet. The center of the large-diameter section is offset from the straight line, and consequently, the length of a portion of the inner wall of the injection hole body, the portion facing the axis of the valve seat, is asymmetric relative to the straight line.

L'invention concerne une soupape d'injection de carburant configurée d'une manière telle que chacun des trous d'injection comporte un corps de trou d'injection et une section de grand diamètre qui est située de manière adjacente et en aval par rapport au corps de trou d'injection et qui constitue la sortie du trou d'injection. Quand chacun des trous d'injection est projeté de manière perpendiculaire sur un plan perpendiculaire par rapport au siège de soupape, le centre de l'entrée du corps de trou d'injection et le centre de la sortie de celui-ci sont agencés d'une manière telle que les centres sont agencés côte à côte sur une ligne droite radiale traversant l'axe du siège de soupape et d'une manière telle que le centre de la sortie est plus éloigné de l'axe du siège de soupape que du centre de l'entrée. Le centre de la section de grand diamètre est décalé par rapport à la ligne droite, et, par conséquent, la longueur d'une partie de la paroi intérieure du corps de trou d'injection, la partie orientée vers l'axe du siège de soupape, est asymétrique par rapport à la ligne droite.

 燃料噴射弁において、各噴孔は、噴孔本体と、噴孔本体の下流に隣接し噴孔の出口を構成する大径部とから構成されている。各噴孔を弁座軸心に直交する平面に対して垂直に投影したとき、平面上における噴孔本体の入口中心と出口中心とは、それぞれ弁座軸心を通る放射状の直線上に並べて配置され、かつ出口中心が入口中心に対して弁座軸心から離れる方向に配置されている。大径部の中心が直線に対してオフセットされていることにより、噴孔本体の弁座軸心側の噴孔内壁長さが直線に対して非対称となっている。
