<p>A fuel injection valve is configured in such a manner that each of the injection holes comprises an injection hole body and a large-diameter section which is located adjacent to and downstream of the injection hole body and which constitutes the outlet of the injection hole. When each of the injection holes is projected perpendicularly onto a plane perpendicular to the axis of a valve seat, the center of the inlet of the injection hole body and the center of the outlet thereof are arranged on the plane in such a manner that the centers are arranged side by side on a radial straight line passing through the axis of the valve seat and in such a manner that the center of the outlet is farther from the axis of the valve seat than the center of the inlet. The center of the large-diameter section is offset from the straight line, and consequently, the length of a portion of the inner wall of the injection hole body, the portion facing the axis of the valve seat, is asymmetric relative to the straight line.</p> |
