燃料噴射用インジェクタ
Document Type and Number:
Japanese Patent JP7381177
Kind Code:
B2
Abstract:
To improve the sureness of an operation, in an injector which can change an injection direction of atomized fuel according to an engine temperature.SOLUTION: An injector 13 has a constitution in which a nozzle plate 26 is arranged at a tip of a body. The nozzle plate 26 is composed of a base plate 26a in which a fuel injection hole 25 is formed, an outside-temperature sensing deformation part 26b joined to an upper edge of the base plate, and an inside-temperature sensing deformation part 26c joined to a lower end edge of the base plate 26a. The temperature sensing deformation parts 26b, 26c are bimetals which are obtained by pasting two pieces of metal plates. At a warmup operation, fuel is set so as not to progress toward a lower face of an intake port. Therefore, a port wet phenomenon of a warmup drive seat can be prevented. When a temperature of an engine is raised to a certain level, the base plate 26a is changed in a posture in a downward direction by the deformation of the temperature sensing deformation parts 26b, 26c. Accordingly, atomized fuel can be sent into a cylinder while riding on high-velocity intake air.SELECTED DRAWING: Figure 3
