Fuel injector and internal combustion engine having the same |
摘要 |
A laminated fuel swirl element is employed, in which a strong swirl force flow is imparted to the fuel at a remote position relative to an injection hole, while on the other hand, at a position near the fuel injection hole, a weak swirl force is imparted to the fuel. A complex solid cone spray can be obtained in this way, which spray has a superior dispersion characteristic obtained by attracting small diameter droplets, which are generated at an outer peripheral portion of the spray, through a spray portion which is generated in the vicinity of a central area of the spray and has a large velocity.
