    • A fuel injector inhibiting adhesion of deposits and simultaneously improving durability by a simple configuration is provided.A fuel injector having a valve body provided with a main space receiving fuel and an injection hole and a needle movably supported at the valve body and having a seal part at its front end, in which needle the movement causes the seal part to separate from or contact an inner surface of the valve body and thereby open or close a fuel passage communicating the main space and the injection hole of the valve body, the fuel injector characterized in that the injection hole of the valve body is covered by an injection hole coating comprised of a material with a lower adsorption and reactivity with oxygen compared with the material of the valve body itself, and the seal part of the needle is covered by a seal part coating comprised of a material higher in liquid-repellency compared with the material of the needle itself and not forming a metal surface. Preferably, the material of the injection hole coating is gold and the material of the seal part coating is a silica-based coating material.
    • 提供了抑制沉积物附着并同时通过简单构造提高耐久性的燃料喷射器。 一种燃料喷射器,其具有设置有主空间接收燃料和喷射孔的阀体和可移动地支撑在阀体处并且在其前端处具有密封部分的针,其中该运动使得密封部分与或 接触阀体的内表面,从而打开或关闭连通阀体的主空间和喷射孔的燃料通道,该燃料喷射器的特征在于,阀体的喷射孔被包括一个喷射孔涂层 与阀体本身的材料相比具有较低的吸附和反应性的材料,并且针的密封部分被密封部分涂层覆盖,所述密封部分涂层包括与拒水性较高的材料相比, 针本身并不形成金属表面。 优选地,注射孔涂层的材料是金,并且密封部分涂层的材料是二氧化硅基涂层材料。
