摘要： A cylinder of an internal combustion engine is communicated with intake ports. Each of intake valves and each of fuel injection valves are provided to a corresponding one of the intake ports to inject fuel into a combustion chamber through a curved portion and an opening of the corresponding intake port. An injection axis of each fuel injection valve intersects with a surface of the corresponding intake valve placed in a close position at an intersecting point that is located on an upstream side of a central axis of the corresponding intake valve.

摘要： 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.

摘要： A fluid injection nozzle has an injection port plate, an injection port and a protruding portion. The injection port plate is to be mounted on a downstream end of a fluid injection valve so that a center axis thereof is coaxial to the fluid injection valve. The injection port penetrates the injection port plate between an inlet and an outlet. The protruding portion protrudes from an inner surface of the injection port to shift a direction of at least a part of a fluid flow passing through the injection port to flow in a circumferential direction of the inner surface.

摘要： A fuel supply system supplies composite fuel containing alcohol and gasoline to multiple cylinders of an internal combustion engine. The composite fuel includes main-fuel and sub-fuel. The sub-fuel is lower than main-fuel in concentration of alcohol. Each of multiple first fuel injection valves is provided to each of the cylinders for injecting fuel. Each of multiple second fuel injection valves is provided to each of the cylinders for injecting fuel. A fuel inlet portion supplies at least sub-fuel to each of the first fuel injection valves and each of the second fuel injection valves. A selector control unit selects one of main-fuel and sub-fuel supplied through the fuel inlet portion to each of the first fuel injection valves.
