【Abstract】 The EMS control strategy was designed for control of high power common rail diesel engine,which included the judgment and switching of operating conditions,injection control and fuel rail pressure control.Based on the real time simulation system,the strategy was adjusted and optimized by the real-time simulation and the rail pressure and injection control were hence verified.Therefore,the control strategy was feasible and could satisfy the demands of engine bench test.更多还原
