摘要： A fuel injection valve includes a valve body having a valve seat, a nozzle plate arranged on an injection side of the valve body, a valve plug for intermitting fuel injection through the nozzle hole, and a sleeve. The nozzle plate has a nozzle hole through which fuel is injected from the injection side of the valve body. The sleeve makes contact with an end surface of the nozzle plate on an opposite side of the valve body with respect to the nozzle plate to partially cover the nozzle plate. Fuel is injected to an outside of the sleeve through the nozzle hole of the nozzle plate and an opening of the sleeve. The end surface of the nozzle plate makes contact with the sleeve in a contact portion. The contact portion has at least one groove that extends from the opening outwardly with respect to a substantially radial direction of the sleeve.

摘要： In a structure or method of installing an injector in a delivery pipe of a common rail, the injector on which a seal member and a clip member are mounted is inserted into an interior of the delivery pipe in such a manner that the clip member comes in contact with the delivery pipe after the seal member comes in contact with an interior wall of the delivery pipe. This structure or method has an advantage of preventing the foreign material, which is a part of the protection layer peeled off from the delivery pipe due to contact between the clip member and the delivery pipe, from being lodged between the seal member and the inner wall of the delivery pipe.

摘要： A fuel injector has a plurality of fuel injection ports including first injection ports and second injection ports. Injection-port axes of the first injection ports extend to a first space in a combustion chamber. Injection-port axes of the second injection ports extend to a second space in a combustion chamber. An interval of the injection-port axes between adjacent first injection ports is shorter than an interval of the injection-port axes between the first injection port and the second injection port which are adjacent to each other.
