Abstract
A fuel pressure control system for a fuel supply system of an injector of an engine includes: a booster pump for increasing a high-pressure system fuel pressure; a pressure reducing valve for reducing the high-pressure system fuel pressure; and a control device for controlling the booster pump and the pressure reducing valve. The control device includes a valve opening necessity determination unit for the pressure reducing valve. The control device executes a valve opening control for opening the pressure reducing valve. The control device further includes a restriction execution unit for performing a valve opening restriction control in the valve opening control to prevent a pressure exceeding a predetermined target portion threshold pressure from being applied to a target portion.
