Abstract
A fuel pressure control device determines whether it is during a descending period of a plunger descending or an ascending period of the plunger ascending, and puts a first drive mechanism and a second drive mechanism in an energized state during the descending period and in a non-energized state during the ascending period, when there is a pressure reduction request to lower a fuel pressure in a high-pressure passage.
