Abstract
A fuel injector system permits easier control for turning ON/OFF a spill control solenoid valve of a high pressure supply pump. The cam has a greater number of rising slopes for pressurizing the fuel by the plunger than the number of the fuel injection for each rotation of the engine. An electronic control unit controls the closing timing of the spill solenoid valve so that the period of synchronous delivery which is synchronized with the fuel injection is longer than the period of asynchronous delivery which is not synchronized with the fuel injection. Further, the unit adjusts the closing timing of the spill solenoid valve according to engine load.
