ELECTRONIC CONTROL FUEL INJECTION VALVE

摘要

PURPOSE: A fuel injection valve with an electronic control is provided to easily process flow path by forming a second flow path in a control valve housing. CONSTITUTION: A fuel injection valve(100) with an electronic control comprises an injection control unit(300), a nozzle unit(500), a lower pressure chamber(231), and a control needle(240). The injection time and quantity of fuels are controlled as the control needle is independently operated according to control signals. The high pressure fuels are delivered to a lower pressure chamber through the control needle. The fuel injection is rapidly controlled while force for lifting a cutoff needle(330) increases. The cutoff needle secludes a fuel supply to the nozzle unit when the fuels are not injected. The large amount of the fuels is prevented from leaking to a combustion chamber, and the safety is secured as high pressure is not always applied to the nozzle unit.
