(EN) FUEL INJECTION METHOD FOR DIESEL ENGINE AND DIESEL ENGINE
(FR) PROCÉDÉ D'INJECTION DE CARBURANT POUR MOTEUR DIESEL, ET MOTEUR DIESEL
(JA) ディーゼルエンジンの燃料噴射方法及びディーゼルエンジン
要約
(EN)
A diesel engine (1) injects fuel into a combustion chamber (6) from a fuel injection valve (5) to generate sprays (7) in the combustion chamber (6). The axis L1 of the fuel injection valve (5) is offset outward in the radial direction of the cylinder (2) relative to the axis L2 of a cylinder (2). This positions the fuel injection valve (5) at a place on the inner peripheral surface side of the cylinder (2). Further, nozzle holes (5a) of the fuel injection valve (5) are divided into two groups located at the left and right of a straight line formed by interconnecting, in a plan view, the axes L1, L2. Also, the sprays (7) of fuel injected from the nozzle holes (5a) advance in a fan shape in the plan view and, on the side away from the fuel injection valve (5), collide with the inner peripheral surface of the cylinder (2).
(FR)
L'invention concerne un moteur diesel (1) qui injecte le carburant dans une chambre de combustion (6) à partir d'une soupape d'injection (5) afin de générer des pulvérisations (7) dans la chambre de combustion (6). L'axe L1 de la soupape d'injection de carburant (5) est décalé vers l'extérieur dans la direction radiale du cylindre (2) par rapport à l'axe L2 de ce dernier (2). Ceci positionne la soupape d'injection de carburant (5) à un endroit stué sur le côté de la surface périphérique interne du cylindre (2). En outre, les ajutages (5a) de la soupape d'injection de carburant (5) sont divisés en deux groupes situés à gauche et à droite d'une ligne droite formée par l'interconnexion, selon une vue en plan, des axes L1 et L2. Les pulvérisations (7) de carburant injecté par les ajutages (5a) évoluent en formant un éventail, selon une vue en plan, et, sur le côté éloigné de la soupape d'injection de carburant (5) viennent heurter la surface périphérique interne du cylindre (2).

 燃料噴射弁5から燃焼室6内に燃料を噴射して、前記燃焼室6内に噴霧7を生成させるディーゼルエンジン1において、前記燃料噴射弁5の軸心L1をシリンダ2の軸心L2に対しシリンダ2径方向外方へオフセットして、燃料噴射弁5をシリンダ2の内周面側に位置させると共に、前記燃料噴射弁5の噴孔5aを、平面視で前記軸心L1とL2を結んで形成された直線を基準として左右の二つのグループに分け、且つ、噴孔5aから噴射された燃料の噴霧7は、平面視で扇状に進行し、燃料噴射弁5から離反した側においてシリンダ2の内周面に衝突するよう構成した。
