Abstract
In a nozzle plate, a portion of fuel flowing out from a fuel injection port of the fuel injection device is atomized by impinging on an interference body. At the same time, the flow of the portion of fuel is sharply bent and impinges on fuel which straightly advances and passes through a nozzle hole and an orifice thus turning the flow of fuel into a turbulent flow. Further, both end portions of the orifice form non-rounded sharpened corner portions. Hence, a liquid film of fuel injected from the corner portions and areas in the vicinity of the corner portions of the orifice is formed into a thin sharpened and pointed state whereby an end portion of the liquid film of fuel injected from the orifice is easily atomized due to a friction between the end portion of the liquid film of fuel and air.
