PROBLEM TO BE SOLVED: To provide a fuel supply control device which is high in quietness by suppressing a sound which is generated when a cam shaft and a plunger abut on each other.SOLUTION: In a fuel supply control device, fuel flowing into a pump chamber 12 is compressed by the close of a flow-in port 121 by a first electromagnetic valve 100 and the slide movement of a plunger 11 in a pump chamber 12, and the fuel is discharged to the outside. The fuel supply control device comprises rotation number detection means 51 which detects a rotation number R of a cam shaft 8, and when there is no discharge command signal being a signal for discharging the fuel to the outside, and the rotation number R detected by the rotation number detection means 51 is not smaller than a prescribed rotation number Rth, control means 5 valve-closes the first electromagnetic valve 100 so that the plunger 11 compresses the fuel even if the fuel discharged to the outside is not necessary. |
