| Abstract: | Based on the control demand of high pressure common rail system in diesel engine,electric control unit(ECU) based on Motorola MPC555 32 bits series chip is developed.Using the design method of modularization,an ECU's hardware is developed,including driving circuit for solenoid and power supply circuit.By means of the MPC555's TPU3 module,input and injection control are performed and a control software is programmed with C language.The common rail system's pressure is controlled with a PID fuzzy algorithm.After bench test,it's shown that ECU can meet the control demand of high pressure common rail system in diesel engine. |
