Abstract
A common rail fuel injection device includes first and second flow rate regulating valves for regulating a delivery volume of a pressurized fuel feed pump that feeds pressurized fuel to a common rail, a pressure reducing valve for reducing a common rail pressure, and a control device. The control device for the common rail fuel injection device includes a first drive controlling unit that controls a first electromagnetic driving unit for the second flow rate regulating valve and a second electromagnetic driving unit for the pressure reducing valve, and a second drive controlling unit that controls a third electromagnetic driving unit for the first flow rate regulating valve. The first drive controlling unit prohibits a drive instruction from being sent to the second flow rate regulating valve when the first drive controlling unit sends a drive instruction to the pressure reducing valve.
