【正文】 chnology in this context bred. Electronically controlled high pressure mon rail diesel engine as an energysaving environmental protection, energy saving and environmental protection in the growing awareness of today, has bee an inevitable vehicle engine selection. Its injection control and fault monitoring policy research, to improve the fuel injection control precision, to achieve energy reduction targets, improve stability and reliability of the engine is running and optimizing the overall performance of the engine has important practical significance. This paper describes the foreign countries, electronically controlled high pressure mon rail diesel engine within the development of a detailed analysis of the position and work of high pressure mon rail principle focuses on electronically controlled high pressure mon rail system fault diagnosis and repair its concrete steps, the last cited Havel , Xichai other cars often failures were analyzed to understand.Keywords: High pressure mon
