摘要： At fuel downstream end of a valve body, there is arranged an injection port plate formed into a thin disc shape. In the injection port plate, there are formed four injection ports having fuel inlets in a common circumference on the center axis of the injection port plate. The injection ports are formed in the fuel injecting direction apart from the center axis of the injection port plate. In each injection port, with respect to the injection port axis joining the center of the fuel inlet and the center of the fuel outlet of each injection port, the injection port inner circumference more distant from the center axis of the injection port plate is more inclined toward the outer circumference with respect to the center axis than the injection port inner circumference less distance from the center axis of the injection port plate with respect to the injection port axis.

摘要： A fuel injector has a chamber between a valve body and a plate in which a plurality of through holes are formed. The chamber has a diameter larger than that of an opening of the valve body. The through holes are opened at an outer chamber area shaded by the valve body are distanced from an outer wall of the chamber more than a diameter of the through hole. Fuel flowing along an inner inclined surface of the valve body turns to the through holes and flows into the through hole from all directions and collides with each other at inlets of the through hole. Therefore, injected fuel has a lot of turbulences and is finely atomized.

摘要： A fuel injection apparatus which prevents delay of the pressurization of the fuel injected and deterioration of the starting characteristic at the time of engine cold starts and the resultant increase in emission of hydrocarbons by leading to an auxiliary startup pump the hydraulic pressure generated in the hydraulic cylinders supporting the driver's seat when the driver gets in the car and sits on the seat before startup, converts this to a high fuel pressure by large and small diameter cylinders, and obtains a fuel spray with a good atomization by a high fuel pressure immediately after startup. Other forces which can be used are the force generated in a hydraulic damper of a suspension by the weight of the driver when getting in the car, the force of opening the driver's side door, the force of stepping on the brake pedal, etc.

摘要： It is an object of the invention to provide a method of working an injection hole of an electromagnetic type fuel injection valve so that when extrusion by using a punch is adopted, the punch does not break, even in the case where a central axis line of the injection hole of the electromagnetic type fuel injection valve is inclined to a line perpendicular to a face of a plate-like material to be punched. A front end, tapered portion of the punch is inclined in a direction opposed to a plate-like material relative to a central axis line of the punch to facilitate the punch along a sliding, inner face of a punch holder. While achieving a reduction in production cost, the divergent-shaped injection hole can accurately be formed in the plate-like material. A side force (Fs) is produced when the front end portion of the punch impinges on the plate-like material. The side force (Fs) is canceled by a reaction force (Fr) on a side opposed to the plate-like material and a bending moment potentially causing breakage of the punch is avoided.
摘要翻译：本发明的目的是提供一种加工电磁式燃料喷射阀的喷射孔的方法，使得当通过使用冲头进行挤出时，冲头不会断裂，即使在中心轴线电磁式燃料喷射阀的喷射孔与垂直于要冲压的板状材料的表面垂直的线倾斜。冲头的前端，锥形部分相对于板状材料相对于冲头的中心轴线倾斜，以便沿着冲头保持器的滑动内表面的冲头。在实现生产成本降低的同时，可以在板状材料中精确地形成发散型注入孔。当冲头的前端部撞击板状材料时，产生侧向力（Fs）。侧力（Fs）被与板状材料相反的一侧的反作用力（Fr）抵消，并且避免了潜在地引起冲头破裂的弯矩。
