Abstract:
Disclosed is a fuel injection valve comprising: a fuel injection orifice provided in a downstream side of a valve seat which a valve body moves toward and away from; a swirl chamber having a swirl passage formed around the entry opening of the fuel injection orifice; and a transverse passage whose end is opened in an inner circumferential wall of the swirl chamber in order to provide a fuel into the swirl chamber, wherein a center of the entry opening is shifted from a first position where the velocity component in the swirl direction of the fuel can be maximized to a second position where the velocity component in the swirl direction is reduced, and where a velocity component in a center axis direction of the fuel injection orifice is enhanced. Thereby, it is possible to easily adjust a fuel injection amount and a spray angle.
