Abstract: 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.

Abstract: 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.

Abstract: 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.
