ABSTRACT:
A fuel injector including a valve housing having a fuel injection hole formed at a front end of the valve housing; a valve movably provided int he valve housing so as to open and close the fuel injection hole; a nozzle fixedly mounted to a front end of the valve housing; and a fuel colliding member provided in the nozzle and positioned in alignment with the fuel injection hole in front thereof. A size of the fuel colliding member is smaller in cross section perpendicular to an axis of the fuel injector than that of the fuel injection hole. Accordingly, a radially inside part of a columnar fuel after collision with the fuel colliding member further collides with a radially outside part of the columnar fuel passing outside the fuel colliding member to accelerate atomization of the fuel without reducing a velocity of flow of the fuel.
