    • An internal combustion engine has a cylinder, a cylinder head mounted to the cylinder, a piston disposed in the cylinder, and a fuel injection valve. A combustion chamber is defined by the piston, the cylinder head and the cylinder. The fuel injection valve has a plurality of injection holes that injects fuel directly inside the cylinder from a side of the combustion chamber. The injection holes inject fuel in a spray shape with an overall shape, which is formed by a plurality of sprays being injected from the injection holes. The overall shape expands toward the cylinder head and forms one part of a conical shape that is dented near the piston. Central axes of some of the injection holes are oriented toward a boundary portion near the exhaust valve formed at a crown surface of the piston and an inner wall of the cylinder when fuel is injected.
    • 内燃机具有气缸,安装在气缸上的气缸盖,设置在汽缸中的活塞和燃料喷射阀。 燃烧室由活塞,气缸盖和气缸限定。 燃料喷射阀具有多个喷射孔,其从燃烧室的侧面直接在气缸内喷射燃料。 喷射孔喷射具有整体形状的喷雾形式,其由从喷射孔喷射的多个喷雾形成。 整体形状向气缸盖膨胀,形成在活塞附近凹陷的圆锥形的一部分。 一些喷射孔的中心轴朝向形成在活塞的冠面处的排气阀附近的边界部分和在燃料喷射时的气缸的内壁。
