。The head-side pump chamber of the plunger, which performs reciprocating one-rotation movement to suction and pressure feed and distribute fuel, communicates with the low-pressure fuel system via the first electromagnetic valve, and the head-end side outer circumferential surface of the plunger The intake port and the low pressure fuel line are connected through a second electromagnetic valve, and when at least one of the fuel temperature and the battery voltage is below a predetermined set value at the time of starting the internal combustion engine. Closing the first solenoid valve shuts off the pump chamber and the low-pressure fuel line, and opening the second solenoid valve connects the suction port and the low-pressure fuel line. , when the rotational speed after starting reaches a predetermined set value, the second solenoid valve is closed to cut off the intake port and the low-pressure fuel line, and the first solenoid valve is controlled to open and close. A distribution type fuel injection pump characterized in that it is configured so that normal operation can be obtained by controlling fuel suction, injection timing, and injection amount.
