Abstract:
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.
