【Abstract】 The hardware of high-pressure common-rail-injection control system was composed of an in- dustrial computer and the developed driver circuit.The control software was programmed with the advanced program language and VxD technology under the Windows operation system,which could control the com- mon-rail-injection system in real time and was in humanization for the user.The experimental results show that this control system can effectively control the common rail pressure by PID method.Compared with the fuel consumption of the tested diesel engine,the fuel supply ability of this common rail injection system meets the requirements.更多还原
