Abstract
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.
