摘要： PROBLEM TO BE SOLVED: To improve combustion in idling and low-load operation in a fuel injection nozzle of a direct-injection diesel engine or the like.
SOLUTION: In the fuel injection nozzle, where rows of nozzle holes are formed in two stages at the lower end section of a nozzle body 8, the ratio of nozzle hole length s2 at the lower stage to a diameter d2 in the nozzle hole 12 is set to be equal to or less than nozzle hole length s1 to a diameter d1 in the nozzle hole 11 at the upper stage. Preferably, the diameter d2 of the nozzle hole 12 at the lower stage is formed to be smaller than the diameter d1 of the nozzle hole 11 at the upper stage, and the nozzle hole length s2 of the nozzle hole 12 at the lower stage is formed to be shorter than the nozzle hole length s1 of the nozzle hole 11 at the upper stage, thus preventing fuel being injected from the nozzle hole 12 at the lower stage from colliding against a combustion chamber bottom surface 6a before being atomized fully, improving combustion, and preventing the aging of combustion by the deposition of carbon.
