Patent ID: 8100109

Claim:
A control device for an in-cylinder injection internal combustion engine that makes fuel have high pressure through a high pressure pump to supply fuel to an injector and then injects fuel directly into a cylinder from the injector, the control device comprising: a fuel pressure detecting means for detecting pressure of fuel that is supplied to the injector; a target fuel pressure setting means for setting a target fuel pressure in accordance with an operating state of the engine; a fuel pressure control means for feedback-controlling an amount of fuel discharged from the high pressure pump such that the pressure of fuel detected by the fuel pressure detecting means accords with the target fuel pressure; a stop predicting means for determining whether the engine is about to stop; and a target fuel pressure gradual change means for decreasing the target fuel pressure gradually to a final target fuel pressure which is lower than normal, when it is determined by the stop predicting means that the engine is about to stop.
