CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

摘要

Provided is a control device for an internal combustion engine which can decrease a load applied to a drive system of a high pressure pump at the time of restarting the internal combustion engine from an automatic stop state of the internal combustion engine. A control device for an internal combustion engine which can execute an idling stop control includes: an idling stop condition satisfaction detection part which detects that a predetermined idling stop condition is satisfied and outputs an instruction to automatically stop the internal combustion engine; a restarting condition satisfaction detection part which detects that a predetermined restarting condition is satisfied during an automatic stop of the internal combustion engine and outputs an instruction to restart the internal combustion engine; a rail pressure detection part which detects pressure in the common rail; and a pressure control valve control part which opens the pressure control valve before restarting the internal combustion engine when the pressure in the common rail becomes a predetermined threshold value or more at the time of satisfying the restarting condition.
