PURPOSE:To control an injection quantity in accordance with an operational condition, by providing an injection start spill ring and an injection end spill ring to a distributor type injection pump of inner cam type and controlling overflow timing. CONSTITUTION:An electronic controller 19 calculates an accurate injection quantity corresponding to an operational condition to feed a driving signal to a hydraulic control unit 12 and a rotor solenoid 16. A distributing member 2 is moved in the shaft direction by opening and closing a solenoid valve 12a of the unit 12, and the relation of a relative position between a spill port 9a of a spill ring 9 and a spill port 21 is controlled then injection start timing is controlled. While a spill ring 10 is independently controlled by the rotary solenoid 16, and the relation of a relative position between a spill port 10a and a spill port 22 is controlled, then injection end timing is controlled. |
