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 controls 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 cut-off needle of an injection control unit by delivering through a control needle high pressure fuel to a lower pressure chamber, and when the fuel injection is not carried out, fuel is not supplied to a nozzle unit, thereby preventing the high pressure from being applied to the nozzle unit at normal times, and prevents a large amount of fuel from being leaked into a combustion chamber when a component such as the needle is damaged, and processing thereof is easy due to the simple structure of a second fluid channel. |
