The type of questions for the graduation thesis, subject content 1) driving technique using dual power technology, power device gate, realize the diesel engine high-pressure common rail injection valve control system;2) using SCM and related driving circuit to complete the diesel engine high-pressure common rail fuel injection valve control system design;3) for diesel engine high-pressure common rail to do preliminary research work needed for fuel injection valve control system. The basic task for based on understanding injection solenoid valve drive requirements, characteristics and improve the injector solenoid valve drive performance basic method, complete the diesel engine high-pressure common rail in hardware and software design, injection valve control system each function block programming and programming;2) completed the system hardware and software design of each functional block and function debugging using special software exploitation system;3) by diesel engine high-pressure common rail fuel injection valve control system with the result of performance test, the correctness and practicability of the design of the control system. With the increasingly strict emission regulation and development of diesel engine electronic fuel injection technology, high pressure co
