ELECTRONICALLY CONTROLLED FUEL INJECTION VALVE

摘要

The present invention relates to an electronically controlled fuel injection valve, and unlike a conventional mechanical fuel injection valve, the electronically controlled fuel injection valve provided by the present invention can control the injection time and the injection amount according to a control signal, independent of driving conditions of an engine, enables swift control of the fuel injection by using as a method for controlling the fuel injection a method that increases the strength of lifting up a needle of a nozzle by delivering through a control needle high pressure fuel to a lower pressure chamber, and assembly and replacement of the components and precise processing of the components are easy due to the simple structure thereof.
