<P>PROBLEM TO BE SOLVED: To provide a fuel injection device which increases flexibility of the rate of fuel injection, reducing an exhaust gas and improving efficiency. <P>SOLUTION: The fuel injection device is equipped with: a fuel injection valve 7 injecting fuel; a fuel injection pipe 8 introducing the fuel into the fuel injection valve 7; a fuel injection pump 6 feeding the fuel from the fuel tank 1 to the fuel injection pipe 8; fuel return pipes 9, 13 returning fuel from the fuel injection pipe 8 to the fuel tank 1; a solenoid valve 12 intermitting the fuel return pipe 9; and a solenoid valve 16 intermitting the fuel return pipe 13. Fuel flow rate in opening the solenoid valve 12 is set up less than that in opening the solenoid valve 16, and when the fuel is supplied into the fuel injection valve 7, the solenoid valve 12 is precedently closed, the solenoid valve 16 is successively closed, the solenoid valve 12 is opened simultaneously and the solenoid valve 12 is closed subsequently. <P>COPYRIGHT: (C)2003,JPO |
