【正文】 es to improve greatly, not only optimized vehicle performance greatly, but also plicated the vehicle control system39。然而，目前關(guān)于發(fā)動(dòng)機(jī)故障自診斷系統(tǒng)設(shè)計(jì)的方法很多，但是在詳細(xì)分類討論各自方法的實(shí)施和綜合對(duì)比不同方法的優(yōu)缺點(diǎn)這一領(lǐng)域還是空白，本論文目的就是填充這一空白，完善汽車故障診斷體系，具有一定的理論價(jià)值，同時(shí)也便于查閱，具有一定的參考價(jià)值。這樣就使得發(fā)動(dòng)機(jī)成為汽車故障診斷與檢測的重點(diǎn)對(duì)象，由于我國汽車工業(yè)發(fā)展較晚，汽車電子與發(fā)達(dá)國家差距很大，所以進(jìn)行汽車故障診斷技術(shù)的研究對(duì)于改善和提高我國的汽車檢測診斷技術(shù)非常重要。畢業(yè)設(shè)計(jì)（論文）豐田凌志400發(fā)動(dòng)機(jī)電控系統(tǒng)故障的診斷與檢修目 錄摘要……………………………………………………………………………2關(guān)鍵詞…………………………………………………………………………21. 緒論………………………………………………………………………3……………………………………………3…………………………………………………32. 電控發(fā)動(dòng)機(jī)的概述………………………………………………………4………………………………………4 ………………………………………………53. 豐田凌志400電控發(fā)動(dòng)機(jī)典型和疑難故障診斷…………………………6……………………………………………6……………………………………7 ………………………………………………8……………………………………………9………………………………………………………10………………………………………………………………11………………………………………………………………12………………………………………………………………13………………………………………………………………13…………………………………………………………………………15豐田凌志400發(fā)動(dòng)機(jī)電控系統(tǒng)故障的診斷與檢修摘 要發(fā)動(dòng)機(jī)是汽車的重要組成，是車輛運(yùn)行的動(dòng)力來源。隨著其自動(dòng)化程度的不斷提高、其結(jié)構(gòu)也變得越來越復(fù)雜，因此發(fā)動(dòng)機(jī)故障發(fā)生的頻率增大，其診斷難度也不斷提高。汽車發(fā)動(dòng)機(jī)故障診斷方法的研究是隨著汽車技術(shù)不斷進(jìn)步而逐步完善的過程，因此建立科學(xué)、系統(tǒng)、合理、完善的汽車故障診斷體系，已成為目前汽車故障診斷的必然要求和技術(shù)發(fā)展的必然趨勢。關(guān)鍵字：電控發(fā)動(dòng)機(jī) 故障診斷 診斷思路AbstractEngines are the main assembly of motor vehicles, are important power sources for vehicles. With its continuous improvement of working performance and the level of automation, vehicles39。s structure and function. However, once the control system took place fault diagnosis and repair has bee more difficult, there will be higher demand to maintenance man39。s automotive diagnostic techniques, as well as it has important practical significance.Automotive engine fault diagnosis method gradually improved with the continuous process of automotive technology. Set up a scientific, systematic, rational, prehensive system for automotive fault diagnosis has bee an inevitable requirement and an inevitable technological development trend to the car fault diagnosis. At present, however, there are many different types methods about the engine fault selfdiagnosis system design, but many of them are varied and messy,there still blank in a detailed discussion at the implementation of their respective,except that general parison of the advantages and disadvantages of different methods in this field, the purpose of this paper is to fill this blank, not only with a high theoretical value, but also easy to consult and have the certain reference value . 1. 緒 論. 電控發(fā)動(dòng)機(jī)的發(fā)展歷史1951年，美國奔迪克斯發(fā)明了電子控制燃油噴射裝置，并且奠定了現(xiàn)代燃油噴射裝置基本構(gòu)造的基礎(chǔ)。代博世公司在發(fā)表D—Jetronic后的
