Kind Code:
A
Abstract:
To reduce attachment of fuel to an injector.SOLUTION: A fuel injection device provided on an engine has: a nozzle portion having an injection hole for injecting a fuel; and a body portion on which a fuel flow channel for supplying the fuel to the injection hole is formed. The fuel injection device has a first electrode for charging internal fuel as the fuel in the fuel flow channel, and a second electrode for charging external fuel as the fuel attached to a tip of the nozzle portion. The fuel injection device has a power source circuit portion for applying voltage to the first electrode and the second electrode, and a control system for controlling the power source circuit portion. The injector includes a valve element moving to a close position for closing the injection hole and an open position for opening the injection hole, and the control system applies voltage to the first electrode and the second electrode to charge the internal fuel and the external fuel with polarities opposite to each other in a state where the valve element has moved to the close position.SELECTED DRAWING: Figure 8
