Abstract
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.
