【正文】 1，各個(gè)部件，工作原理和工作 過(guò)程，典型故障作了詳細(xì)的介紹。進(jìn)而分析了汽車啟動(dòng)機(jī)的故障 檢測(cè)和排除。然主要是敘述汽車啟動(dòng)機(jī)的結(jié)構(gòu)， 工作原理和工 作過(guò)程，但是這樣可以更清晰的表現(xiàn)出汽車啟動(dòng)機(jī)的故障原理。 本論文對(duì)啟動(dòng)機(jī)的常見(jiàn)故障作了診斷和研究。 關(guān)鍵詞： 啟動(dòng)機(jī)：故障檢測(cè)：故障排除 2 Summary In this paper the startup machine as the center, this article will be divided into five most. First of all a general described the startup system position, working process and principle, and then start machine as the startup system is the important ponent of detailed and prehensive introduction to start machine structure, play a role, the main types and the mon principle of several start machine figure, and in principle the graph is an opportunity, deeply describes the startup process and the principle of the machine work. In addition, with auto possession of year by year climbed, auto aftersales service quality especially the maintenance technology still needs further strengthen, or a car service market to meet consumer demand, so this paper from the point of view of car maintenance, detailed start to describe the major ponents of the machine maintenance and overhaul method, start machine mon failure detection steps and elimination method, and finally for the car in real use started in in machine machine start typical fault cases and adverse reaction makes a detailed analysis and introduce diagnosis and elimination method! Keywords: start system。、 Start machine、 Principle、 The maintenance and repair、 Case 3 第 1 章 緒論 汽車啟動(dòng)系統(tǒng)是汽車發(fā)動(dòng)機(jī)五大系統(tǒng)之一，而啟動(dòng)機(jī)則為啟動(dòng)系統(tǒng)中的重中之重。為使靜止的汽車發(fā)動(dòng)機(jī)進(jìn)入工作狀態(tài)，必須依靠于啟動(dòng)產(chǎn)生轉(zhuǎn)矩外力從而通過(guò)飛輪使曲軸旋轉(zhuǎn)，發(fā)動(dòng)機(jī)再在點(diǎn)火系統(tǒng)、燃料供給系統(tǒng)等作用下而自動(dòng)運(yùn)轉(zhuǎn)。因此，對(duì)汽車啟動(dòng)機(jī)結(jié)構(gòu)組成的掌握與了解、 啟動(dòng)機(jī)故障的檢測(cè)與診斷、平常的維護(hù)與保養(yǎng)工作是十分重要的，因?yàn)閱?dòng)機(jī)啟動(dòng)汽車是當(dāng)代轎車啟動(dòng)的唯一方式！ 第 2 章 啟動(dòng)機(jī)的相關(guān)簡(jiǎn)介 啟動(dòng)機(jī)的組成與作用 組成 汽車啟動(dòng)系統(tǒng)作為汽車發(fā)動(dòng)機(jī)的五大系統(tǒng)之一，其主要由蓄電池、啟動(dòng)機(jī)、點(diǎn)火開(kāi)關(guān)、啟動(dòng)繼電器、保險(xiǎn)等組成，而啟動(dòng)機(jī)則被安裝在汽車發(fā)動(dòng)機(jī)飛輪殼的前端蓋的座孔上。 作用 發(fā)動(dòng)機(jī)在燃料供給系統(tǒng)、點(diǎn)火系統(tǒng)、汽缸壓力正常的情況下依靠外力使汽車發(fā)動(dòng)機(jī)曲軸的轉(zhuǎn)速達(dá)到一定適應(yīng)值即可自動(dòng)運(yùn)行。因此汽車啟動(dòng)機(jī)的作用是通過(guò)啟動(dòng)機(jī)轉(zhuǎn)動(dòng)曲軸，從而啟動(dòng)發(fā)動(dòng)機(jī) ，發(fā)動(dòng)機(jī)被啟動(dòng)以后，啟動(dòng)系統(tǒng)便自動(dòng)停止工作。 啟
