A double electronic valves fuel system was established by adopting an electronic unit pump and an electronic injector of common rail. The electronic unit pump is used for fuel supply adjusting and the electronic injector of common rail is used for fuel injection control. Subsequently, the characteristics of the fuel system were analyzed by experiment and simulation. The different fuel injection laws were obtained with different time intervals from fuel supply advance angle to fuel injection advance angle. The pilot injection was realized by means of two times injector controls during the course of fuel supply. With prolonged fuel supply time, the high pressure injection was realized at low speed. The results show that the double valves fuel system reserves the advantages of traditional fuel system and has the more flexible characteristics during the circle of diesel, which will be more favorable to the dynamic performance of diesel.
