    • Axis lines of first and second fuel injection valves are offset from first and second cylinder center lines of first and second combustion chambers by way of moving the first and second fuel injection valves along cam shafts by constituting limits by bringing fuel injection ranges of the first and second fuel injection valves to inner walls of opening portions. Even when the positions of the intake manifolds are obliged to move along the cam shafts, fuel injected from the fuel injection valves can be made to be difficult to adhere to the inner walls of the opening portions and vaporization of fuel can be expedited. Therefore, a mixture in the combustion chambers can be made uniform and engine performance such as response performance of engine rotation, fuel consumption, exhaust gas properties, occurrence of knocking or the like when the throttle valve is opened, can be improved.
    • 第一和第二燃料喷射阀的轴线偏离第一和第二燃烧室的第一和第二汽缸中心线,通过沿着凸轮轴移动第一和第二燃料喷射阀,通过使第一和第二燃料喷射阀的燃料喷射范围 第二燃料喷射阀到开口部分的内壁。 即使当进气歧管的位置不得不沿着凸轮轴移动时,也可以使从燃料喷射阀喷射的燃料难以粘附到开口部分的内壁,并且可以加速燃料的蒸发。 因此,能够使燃烧室内的混合气均匀化,并且能够提高发动机旋转的响应性,燃料消耗量,排气特性,爆震时的爆震发生等发动机性能。
