Abstract
A fuel injection valve includes a valve body to which liquid to be injected is supplied. A nozzle tip is connected with an end portion of the valve body. A valve member is installed in the valve body to stop and start a supply of the liquid to the nozzle tip. The nozzle tip has first and second nozzle holes which are formed so that fluid injected through the first nozzle hole is collided with fluid injected through the second nozzle hole and that a ratio between a square root of a cross-sectional area of the first nozzle hole and a square root of a cross-sectional area of the second nozzle hole is within a range 1.25 to 3.5. Therefore, the collided fuel is effectively atomized as a result of a resonance phenomenon by the collision.
