    • A combustion chamber side end portion of a fuel injection valve is placed at a location that overlaps with an imaginary plane, which is perpendicular to a center axis of a cylinder and extends along a portion of a wall surface of an intake port where an intake valve protrudes, or is projected out from the imaginary plane toward a combustion chamber. Alternatively, a center of a fuel injecting side end port of the fuel injection valve, which injects fuel into intake air that flows in a branch port branched from the intake port, may be placed on the center axis side of the intake valve in a radial direction of the cylinder. Further alternatively, an upstream side fuel injection valve may inject fuel into intake air that flows in the intake port, and a downstream side fuel injection valve may inject fuel into intake air that flows in the branch port branched from the intake port. Alternatively, an injection quantity of fuel may be controlled for each of fuel injection valves, which injects fuel into intake air that flows in the corresponding branch port branched from the intake port.
    • 燃料喷射阀的燃烧室侧端部被放置在与假想平面重叠的位置,假想平面垂直于圆筒的中心轴线并且沿进气口的壁表面的一部分延伸,进气门 从虚拟平面朝向燃烧室突出或突出。 或者,燃料喷射阀的燃料喷射侧端部的中心,其向从进气口分支的分支口流动的进气中喷射燃料,可以在进气阀的中心轴侧以径向 气缸方向。 另外,上游侧燃料喷射阀可以将燃料喷射到在进气口中流动的进气中,并且下游侧燃料喷射阀可以将燃料喷射到从进气口分支的分支口中流动的进气中。 或者,可以对于每个燃料喷射阀控制燃料喷射量,燃料喷射阀将燃料喷射到从进气口分支的相应分支口中流动的进气中。
