Abstract
There is disclosed a fuel injection nozzle which can change a fuel injection direction in accordance with a fuel injection amount. A plurality of pairs of first and second injection ports are formed in a distal end portion of a nozzle body, and are spaced from one another in the direction of the periphery of the nozzle body. The angle of the first injection port relative to the axis of the nozzle body is acute, and is smaller than the angle between the second injection port and the axis of the nozzle body. Inner ends of the first injection ports are disposed at a valve seat, and inner ends of the second injection ports are spaced from the inner ends of the first injection ports toward the distal end of the nozzle body. Each pair of first and second injection ports have a substantially common outer end. When a tapered conical abutment portion of a needle valve is seated on the valve seat, the inner ends of the first injection ports face the out peripheral surface of the abutment portion.
