    摘要： An electronically controlled fuel injection valve can control the time to inject fuel and the amount of fuel to be injected in response to a control signal independently from the operating condition of an engine unlike a traditional mechanical fuel injection valve. The electronically controlled fuel injection valve employs a control method for fuel injection that increases the force of lifting up a cutoff needle of an injection controller by delivering high-pressure fuel to a lower pressure chamber via a control needle, thereby rapidly controlling fuel injection, has a simple structure making it easy to assemble, replace and precisely machine parts, and has a simple flow path structure which facilitates fabrication.

    摘要： Disclosed herein is a fuel injection valve for an internal combustion engine. The fuel injection valve includes a valve body (10), a nozzle (20), a valve plate (30), a main needle spindle (40), a main needle (50), a main needle spring (60), a spring plate (70), a pilot needle spring (80), a pilot needle spindle (90) and a pilot needle (100). In the present invention, both the main needle and the pilot needle are opened or only the pilot needle is opened by compressed high-pressure fuel oil or compressed air, thereby enabling main injection and pilot injection to be separately performed by the single fuel-injection valve. Furthermore, because opening of the main needle valve can be controlled by compressed air for ignition or control of an engine, only the pilot injection may be conducted even without using a separate compression apparatus or the like.

    摘要翻译： 这里公开了一种用于内燃机的燃料喷射阀。 燃料喷射阀包括阀体（10），喷嘴（20），阀板（30），主针轴（40），主针（50），主针弹簧（60），弹簧 导向针（70），先导针弹簧（80），先导针轴（90）和先导针（100）。 在本发明中，主针和先导针都打开，或者只有先导针由压缩的高压燃料油或压缩空气打开，从而能够通过单次燃料喷射单独执行主喷射和先导喷射 阀。 此外，由于可以通过用于点火或控制发动机的压缩空气来控制主针阀的打开，所以即使不使用单独的压缩装置等也可以仅进行引燃喷射。

    摘要： An electronically controlled fuel injection valve can independently control the time to inject fuel and the amount of fuel to be injected in response to a control signal sent from the operating condition of an engine unlike a traditional mechanical fuel injection valve, and employs a control method for fuel injection that increases the force of lifting up a cutoff needle of an injection controller by delivering high-pressure fuel to a lower pressure chamber via a control needle, thereby rapidly controlling fuel injection. The electronically controlled fuel injection valve prevents a nozzle part from being constantly subjected to high pressure due to the nozzle part being not supplied with fuel when fuel is not injected, prevents a large amount of fuel from leaking into a combustion chamber when a part such as a needle is damaged, and simplifies the structure of a second flow path, thereby facilitating fabrication.

    摘要： The present invention relates to a fuel injection pump having a variable pressure chamber which can adjust a fuel injection timing according to each engine load with a simple structure and a lower manufacture cost compared to the conventional injection pump without a separate apparatus for moving a barrel as well as not modifying a shape of a plunger.
    The fuel injection pump having the variable pressure chamber further includes a pressure adjustment means including a contact plug of which lower portion is inserted and installed in the upper cover; a cylinder of which lower portion is inserted and installed in the contact plug and having the variable pressure chamber formed inside thereof; a main fuel pressing hole formed in the upper cover and the barrel to connect the variable pressure chamber of the cylinder and a plunger insertion hole of the barrel; a piston installed in the variable pressure chamber of the cylinder to enable an upward and downward sliding motion thereof; and a manual pressure adjustment unit installed on an upper portion of the cylinder to enable a vertical height adjustment to elastically support the upper portion of the piston.
