It can simulate diesel engine ECU (Engine Control Unit), provide driving control signals of 6 common-rail fuel injectors and a common rail high-pressure pump , driving common-rail system working. The driving signal parameters can be input by user, ease of maintenance personnel on the common-rail high-pressure pump and injector. It can work with a standard diesel pump test bench to finish the the majority of maintenance of high-pressure common-rail system .Its features are as follows:
(1) driving signal modulation in order to ensure the safety in the maintenance of common-rail system

(2) by setting the high-pressure pump drive signal duty cycle to adjust the load of high-pressure pump as well as the rail pressure

(3) driving signal pulse width and frequency of injector are adjustable ,thereby adjust fuel injection quantity
(4) The apparatus has a over-current protection function of solenoid valve drive signal

(5) real-time measurement of oil rail pressure
