Abstract
PURPOSE: To facilitate the control operation of fuel injection timing, by making the control of fuel injection quantity operable when required a fine amount of injection quantity.
CONSTITUTION: In the up-stroke of a cam 12, with a plunger 9 going up and a notched lead 10a closing an oil outlet port 7, the oil pressure of a pulnger chamber 18 goes up to push upward a push-rodded control valve 15. With a top end face of the push-rodded control valve 15 touching the bottom end face of an open-close control valve 13, the control valve 13 is pushed up being made open with the fuel flowing into a center part valve chamber 4. And the fuel is fed to a fuel injection automatic valve with the fuel injection started. Subsequently, further with the plunger 9 going up, the oil outlet port 7 is opened by the notched lead 10b. The plunger chamber 18 is made linking to an oil sump 8, causing the oil pressure to lower, and the push- rodded control valve 15 and the open-close control valve 13 are closed. In this way, a flow of the fuel oil from the accumulator to the fuel injection automatic valve is shut off to finish the operation of injection.
