電控柴油發(fā)動(dòng)機(jī)與傳統(tǒng)柴油機(jī)的主要區(qū)別在于它的燃油供給系統(tǒng) 的不同，前者采用的是電控燃油噴射系統(tǒng)，而后者采用的是機(jī)械式燃油噴射系統(tǒng)。 本文主要介紹了國(guó)外、內(nèi)電控高壓共軌柴油機(jī)的發(fā)展，詳細(xì) 分析了高壓共軌的組成及工作原理，重點(diǎn)介紹電控高壓共軌系統(tǒng)的故障診斷和它的檢修具體步驟，最后列舉了哈弗、錫柴等汽車上經(jīng)常出現(xiàn)的故障進(jìn)行了分析了解。摘 要 I 淮安信息職業(yè)技術(shù)學(xué)院 畢業(yè)論文 題 目 電控高壓共軌柴油機(jī)控制原 理與故障診斷 摘 要 為了滿足日趨嚴(yán)格的排放法規(guī)和進(jìn)一步提高柴油機(jī)的經(jīng)濟(jì)性和動(dòng)力性的要求，電控高壓共軌技術(shù)在這種背景下孕育而生。 關(guān)鍵詞 ： 高壓共軌；電控柴油機(jī)；控制原理；故障診斷 Abstract III Abstract To meet the increasingly stringent diesel emission regulations and to further improve the economy and power of the requirements, electronically controlled high pressure mon rail technology 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 rail。從結(jié)構(gòu)和功能的角度看，柴油機(jī)的電控系統(tǒng)包括燃油系統(tǒng)的電子控制和柴油機(jī)空氣供給系統(tǒng)的電子控制。這期間經(jīng)歷三代。
