Abstract
An ECU feedback controls a discharge amount of a high-pressure pump in such a manner that a detected fuel pressure is consistent with a target fuel pressure. The ECU determines whether engine shut sown is imminent. When the ECU determines that engine shut down is imminent, the target fuel pressure is established lower than a normal fuel pressure. Since the engine is shut down in a condition where the fuel pressure is decreased, a fuel leakage from a fuel injector is unlikely.
