摘要： An electromagnetic fuel injector comprising: a movable member with a valve body provided at one end and an armature made of a magnetic material provided at the other end; a cylindrical core made of a magnetic material, the core being disposed in such a manner that the distal end thereof opposes the armature; an electromagnetic coil disposed around the cylindrical core for producing an electromagnetic force between the cylindrical core and the armature when the coil is energized; and guide sections for guiding the movement of the movable member in the axial direction, the guide sections being disposed in the vicinities of the valve body and the armature of the movable member. The guide section provided in the vicinity of the armature comprises a sliding member made of a non-magnetic material and disposed between the armature and the core. The colliding surface of the core and the armature is coated with a nickel layer which serves as an impact absorbing layer and a chromium oxide layer which serves as a surface hardening layer. A seal ring is provided between the outer periphery of a plug portion of the core and the inner periphery of a casing. The yoke is coupled to the core at a location which is closer to a fuel outlet from the seal ring.

摘要： A fuel injection device directly injecting fuel into a cylinder is exposed to combustion flame and is heated to nearly 300.degree. C. Under such a temperature condition, deposits of carbonization-growing materials of the injected gasoline and a mixture of engine lubricant and the gasoline and soot produced from the deposits become attached onto the end portion of the fuel injection device. By preventing a change in the fuel injection characteristic with time by preventing of deposits and soot from attaching to the fuel injection device, an engine can be maintained in a normal combustion state for a long time. In order to attain this object, a cylindrical cover member with a bottom made of a high thermal conductive material is mechanically fixed to the end portion of the electromagnetic fuel injection valve through an insulator. The cover member is heated by combustion heat of the engine up to a temperature higher than a deposit producing temperature, and accordingly deposits which tend to attach onto the cover member are eliminated.
摘要翻译：直接将燃料喷射到气缸中的燃料喷射装置暴露于燃烧火焰并被加热到接近300℃。在这样的温度条件下，注入汽油的碳化生长材料和发动机润滑剂和汽油的混合物的沉积物以及从沉积物产生的烟灰附着在燃料喷射装置的端部上。通过防止沉积物和烟灰附着到燃料喷射装置，通过防止燃料喷射特性随时间的变化，发动机可以长时间保持在正常燃烧状态。为了达到这个目的，具有由高导热材料制成的底部的圆柱形盖构件通过绝缘体机械地固定到电磁燃料喷射阀的端部。盖构件通过发动机的燃烧热被加热到高于沉积物生成温度的温度，因此消除了倾向于附着到盖构件上的沉积物。

摘要： A valve seat member has a valve seat with a fuel injection aperture. A valve body is movable between a close position wherein the valve body is put on the valve seat and an open position wherein the valve body is separated from the valve seat. A biasing member biases the valve body in a direction of the close position. An electromagnetic coil, upon energization, moves the valve body in a direction of the open position against the biasing force of the biasing member. A nozzle plate is connected to the valve seat member in a manner to cover the fuel injection aperture. The nozzle plate has at a part thereof facing the fuel injection aperture a domed portion that is projected away from the fuel injection aperture. The domed portion has a plurality of fuel injection openings. A side wall extends around and along a periphery of the nozzle plate so as to form a fuel holding recess that is defined by the nozzle plate other than domed portion and the side wall. The fuel holding recess is able to hold a certain amount of a fuel by the force of a surface tension possessed by the fuel.

摘要： For each of the injection holes on the face of a plate member which is disposed in a fuel passage, grooves are provided which run along the circumferential direction of the respective injection holes, and at the positions of the grooves, fuel overflows are formed. As a result, contracted fuel flow portions are formed in the injection holes, so that the maximum flow velocity of fuel is increased at the injection hole outlet portions. Thus, a fuel injection valve for an internal combustion engine is provided, in which the atomization performance near the injection holes is effectively enhanced.

摘要： A fuel inlet opens at one end between a valve seat and an inner surface of a valve housing on which a globe valve slides. The other end of the fuel inlet opens to an external surface of the valve housing. The fuel inlet runs almost in the direction of a central axis of the globe valve so as to prevent the formation of vortex flow around the globe valve. A spiral member is pressure fitted inside the valve housing immediately downstream of the valve seat with the spiral member being formed as a rod with a spiral fuel groove to swirl the fuel along the groove. An outlet orifice for fuel metering is formed immediately downstream of and as near as possible to the spiral member.
