More Information
Summary:PURPOSE: An electronic fuel injection valve using a solenoid and a seat spool is provided to optimize the pressure, injection time, injection hours of injected fuel oil depending on the state of an engine. CONSTITUTION: An electronic fuel injection valve using a solenoid and a seat spool is composed as follows. A P port, an A port, and a T port are formed inside the electronic fuel injection valve in multistage. A seat spool(4) connected to a solenoid(2) is lifted up and selectively opens and closes fuel oil paths connected to the A, P, and T ports to control the relative pressure of fuel oil supplied to a needle chamber(6). The injection time of the fuel oil is controlled by lifting a lower needle(10) which opens and closes a nozzle hole(18).
