ABSTRACT:
A fuel injection control device in which a needle valve of a fuel injector is opened and closed by two valves. The fuel injector has a pressure control chamber and a fuel chamber, and the needle valve opens a fuel injection aperture to inject the fuel in the fuel chamber to the engine when a pressure in the pressure control chamber is relatively high. One valve is provided in a passage which connects a pump, the pressure control chamber, and a reservoir, and the other valve is provided in a passage which connects the pump, the fuel chamber, and the reservoir.
