摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve for reducing the aging effect of the atomizing property of fuel when injected from a nozzle hole.
SOLUTION: A relationship between an inner diameter A of a suck part 30 and a distance B from a center axis c of the suck part 30 to the nozzle hole 31 is set to be 1≤A/2B≤20. Thus, fuel flowing from the suck part 30 into the nozzle hole 31 is injected via the nozzle hole 31 without being separated from the wall face of a valve body 21 forming the nozzle hole 31. The deposition of foreign matters on the wall face forming the nozzle hole 31 is therefore prevented, or even when deposited on the wall face, the foreign matters are removed therefrom by the fuel flowing in the nozzle hole 31. As a result, with the repeated injection of the fuel, there is no change in the injecting property of the fuel injected from the nozzle hole 31 due to the foreign matters deposited on the wall face. This reduces the aging effect of the atomizing property of the fuel when injected.

摘要翻译：要解决的问题：提供一种用于当从喷嘴孔喷射时减少燃料雾化性能的老化效果的燃料喷射阀。解决方案：吸入部30的内径A与从吸引部30的中心轴c到喷嘴孔31的距离B之间的关系设定为1≤A/2B≤20。因此，从吸入部30流入喷嘴孔31的燃料经由喷嘴孔31喷射而不与形成喷嘴孔31的阀体21的壁面分离。异物沉积在壁面上形成因此，防止了喷嘴孔31，或者甚至当沉积在壁面上时，通过在喷嘴孔31中流动的燃料除去异物。结果，随着燃料的重复喷射，由于沉积在壁面上的异物，从喷嘴孔31喷射的燃料的喷射性能。这降低了注入时燃料雾化性能的老化效应。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve hardly absorbing radiant heat by combustion. SOLUTION: The fuel injection valve 10 for directly injecting fuel into a combustion chamber of an internal combustion engine comprises a nozzle part 29 disposed in the combustion chamber 62, a nozzle 25 provided on the nozzle part 29 for injecting fuel into the combustion chamber 62, wherein a surface 27 of the nozzle part 29 exposed in the combustion chamber 62 is mirror-finished. Mirror-finishing of the surface 27 exposed in the combustion chamber 62 causes most part of the radiant heat by combustion to be reflected by the surface 27 and the fuel injection valve 10 can be inhibited from absorbing the radiant heat. Lowering of an injection quantity and deterioration of a spray shape can be prevented and output lowering of the internal combustion engine and deterioration of exhaust emission can be prevented.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve capable of reducing deposit in an injection hole.
SOLUTION: A coating part 41 is provided on an internal wall of a valve body 21 forming the injection hole 25. Coefficient of linear expansion is different between the coating part 41 and deposit. For this reason, when temperature is changed in the valve body 21 or in the vicinity of valve body 21, the deposit adhered to the valve body 21 receives shearing force due to difference in expansion rate in the coating part 41. As a result, the deposit adhered to the inside of the injection hole 25 is peeled off the internal wall of the valve body 21 forming the injection hole 25. The deposit peeled off the internal wall of the valve body 21 is removed by fuel flowing in the inside of the injection hole 25.
