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 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 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 fluid injection valve has: a valve body that is provided with an opening portion at one axial end thereof and is for starting and stopping a supply of a fluid out of the opening portion; and an injection port plate having a plurality of injection ports that penetrate therethrough, the injection port plate being fixed on the one axial end of the valve body to form a fluid chamber between itself and the valve body to accumulate the fluid therein and to which at least a part of the injection ports opens. A circumferential surface of the fluid chamber recedes toward the injection ports so as to decrease a cross-sectional area of the fluid chamber that is taken along a radial direction of the injection port plate and to reserve a predetermined length of distance between itself and the injection ports.

摘要： A fuel injection valve has a nozzle having a valve seat formed along an inner wall of the nozzle. Injection holes are located on an outlet side of the valve seat. An outlet section, at which a fuel outlet of the injection hole is open, is provided to said nozzle on a side opposite to said valve seat. An enlargement section extends away from the valve seat while being gradually enlarged from an edge of said outlet section in a radial direction.
