Abstract (en)
A first electromagnetic valve (100) closes an inflow port (121) and that a plunger (11) slides in a pump chamber (12), thereby compressing fuel flowing into the pump chamber (12) and discharging the fuel to the outside. The fuel supply control device includes a number-of-revolutions sensor (51) for sensing the number of revolutions (R) of a camshaft (8). In a case where a discharge instruction signal is not turned on and where the number of revolutions (R) sensed by the number-of-revolutions sensor (51) is not less than a specified number of revolutions (Rth), even in a case where the fuel does not need to be discharged to the outside, a controller (5) closes the first electromagnetic valve (100) in such a way that the plunger 11 compresses the fuel.
