2、經(jīng)發(fā)展近半世紀，其技術(shù)水平已有了一個質(zhì)的飛躍！大大提高了汽車的經(jīng)濟性與動力性。然而，現(xiàn)代汽車存在多樣性的問題！如：怠速不穩(wěn)、怠速熄火、冷車怠速不良和熱車不良等問題。汽車怠速運轉(zhuǎn)的時間占汽車運轉(zhuǎn)總時間的30%，怠速運轉(zhuǎn)的好壞直接影響到汽車使用中燃油經(jīng)濟性和排放污染的好壞！又能反應(yīng)汽車的技術(shù)性、穩(wěn)定性、動力性等各種技術(shù)指標。怠速工況下的故障率遠遠大于其它工況的故障率。給汽車維修帶來不小的困難！如何檢測和維修怠速中所發(fā)生的各類故障，應(yīng)是我們每個維修人員共同面對的挑戰(zhàn)。關(guān)鍵詞： 怠速不良 怠速不穩(wěn) 故障診斷 1前 言隨著汽車的逐漸普及，汽車維修行業(yè)已成為一個迅速崛起的龐大行業(yè)，并且在社會上越來越得到廣

3、大人民重視。隨著汽車新技術(shù)的不斷發(fā)展，新技術(shù)日新月異，隨之而來的汽車問題也對汽車維修行業(yè)提出了更高更新的要求。汽車維修從業(yè)人員的業(yè)務(wù)素質(zhì)和技術(shù)水平，直接影響到汽車維修質(zhì)量和汽車維修行業(yè)的聲譽。因此，必須加強汽車維修從業(yè)人員的素質(zhì)和技術(shù)培訓，提高為汽車維修行業(yè)服務(wù)的本領(lǐng)。國家標準GB/T167391997汽車維修業(yè)開業(yè)條件中明確規(guī)定：“各工種技術(shù)工人必須經(jīng)過專業(yè)培訓，取得工人技術(shù)等級證書，并經(jīng)交通行業(yè)培訓，取得上崗證，持證上崗”。國家勞動和社會保障部也制定了對汽車維修從業(yè)人員實行從業(yè)制格制度。為貫徹落實好上述有關(guān)持證上崗制度的規(guī)定，搞好汽車維修從業(yè)人員的崗位培訓工作，我在此論述有關(guān)汽車怠速方面不

4、良問題的故障原因和控制措施，使大家能學習到有關(guān)怠速不良問題的技術(shù)知識，可供大家參考學習。為汽修行業(yè)的良好發(fā)展做出一份力量。2微型車的概述2.1微型車定義微型車也被稱為A00級車，一般情況下，屬于該級別的車其軸距在2.0米至2.3米之間，車身在4.0米之內(nèi)，搭載的發(fā)動機排量在1.0升左右。L排量范圍的轎車，稱為超微型轎車。2.2微型車的發(fā)展前景2008年微型車逆市上行、一枝獨秀是多方面原因共同促成。經(jīng)濟上：處于“寒冬”情況下，消費者出于節(jié)能環(huán)保因素和自身利益的考慮，促使消費者理性選擇了物美價廉、適應(yīng)性強、油耗低的微型車。政策上：隨著中國消費稅的調(diào)整和燃油稅的開征，中國汽車產(chǎn)業(yè)政策也正進一步向微型

5、車領(lǐng)域傾斜，消費者購置微型車的成本明顯降低。企業(yè)上：由于微型車行業(yè)銷量上升，各大汽車集團推出新款微型車，由于物美價廉、生產(chǎn)資料和“國情車,正符合金融危機下的人民群眾要求。綜上所述，微型車關(guān)注度迅速上升，國家政策支持和經(jīng)濟形勢明顯好轉(zhuǎn)，汽車市場也持續(xù)火熱，微型車逐漸升溫。使得微型車發(fā)展為家庭主要代步工具。但事物都有兩面性，微型車在新技術(shù)發(fā)展的同時，一些故障也頻頻出現(xiàn)，而且故障現(xiàn)象呈現(xiàn)復(fù)雜性、多樣性的一些“疑難雜癥”，使得維修工作也很艱難！3 汽車故障的診斷與檢測3.1故障診斷一般原則1、先思后行 對故障現(xiàn)象先進行綜合分析，了解故障原因后再進行故障檢查。可避免檢查的盲目性，迅速排除故障。 2、先外

6、后內(nèi) 先檢查電控系統(tǒng)以外的可能故障予以檢查。 3、先簡后繁 能以簡單方法檢查的可能故障部位應(yīng)優(yōu)先檢查。如：直觀檢查最為簡單，我們可以用問、看、摸、聽、嗅和試等直觀檢查方法，將一些較為顯露的故障部位找出來。4、先易后難 由于結(jié)構(gòu)特點和使用環(huán)境等原因，發(fā)動機的某一故障現(xiàn)象通常是由一些總成部分的原因引起的，應(yīng)先對這些常見故障部位進行檢查。若還不能找出故障在找其它不常見的故障部位，可迅速排除故障。 5、代碼優(yōu)先 有故障代碼的汽車，在對汽車檢查前，按廠家提供的方法，讀取故障代碼，再按故障代碼的內(nèi)容排除故障。 6、先備后用 檢測微機控制系統(tǒng)元件性能的好壞、電氣線路是否正常，常以其電壓或電阻等參數(shù)來判斷。4

7、 怠速的基本概述4.1 怠速定義首先，介紹一下怠速不是一種速度，而是一種工作工況。其次，介紹一下我們把汽車發(fā)動機工作狀態(tài)分為多種工況，如加速工況、減速工況、全負荷工況、怠速工況等，其中怠速工況我們簡稱“怠速”。怠速定義是指發(fā)動機空轉(zhuǎn)運轉(zhuǎn)時，完全放松油門油門踏板，這時發(fā)動機就處于怠速狀態(tài)。發(fā)動機怠速時的轉(zhuǎn)速被稱為怠速轉(zhuǎn)速，它是維持發(fā)動機對外沒有輸出功率時的最低轉(zhuǎn)速。怠速轉(zhuǎn)速可以通過調(diào)整節(jié)氣門大小等來調(diào)整其高低，至到調(diào)到怠速轉(zhuǎn)速以發(fā)動機不抖動、耗油最少時的最低轉(zhuǎn)速為最佳。4.2怠速不良現(xiàn)象4.2.1怠速不穩(wěn)，易熄火1】故障現(xiàn)象：發(fā)動機起動正常，但不論冷車或熱車，怠速均不穩(wěn)，怠速轉(zhuǎn)速過低，易熄火。2

10、油壓力。怠速時的燃油壓力應(yīng)為250kpa左右。如燃油壓力偏低，應(yīng)檢查油壓調(diào)節(jié)器、電動汽油泵、汽油濾清器及電動汽油泵的進油濾網(wǎng)、連接管路等。9、 調(diào)整發(fā)動機怠速。檢查空氣流量計是否卡滯，檢查氣缸壓縮壓力。如壓力低于0.8Mpa，應(yīng)拆檢發(fā)動機。4.2.2冷態(tài)怠速不穩(wěn)，易熄火1】故障現(xiàn)象：發(fā)動機冷態(tài)運轉(zhuǎn)時怠速不穩(wěn)或過低，易熄火，冷態(tài)后怠速恢復(fù)正常。2】故障原因：1、 附加空氣閥故障。2、 怠速控制閥故障。3、 冷卻液溫度傳感器故障。3】故障診斷與排除：1、 先進行故障自診斷，檢查有無故障代碼。如果有，按故障代碼查找故障部位。2、 檢查附加空氣閥。拆下附加空氣閥，檢查在冷態(tài)時附加空氣閥的閥門是否開啟，

13、關(guān)閉。應(yīng)檢修或更換。4、 檢查冷卻液溫度傳感器。若拔下冷卻液溫度傳感器線束插頭后，發(fā)動機怠速好轉(zhuǎn)，說明冷卻液溫度傳感器有故障，應(yīng)檢修或更換。5、 檢查怠速控制閥。發(fā)動機熄火后拔下怠速控制閥線束插頭，待起動后再插上，如果發(fā)動機隨之變化，說明怠速控制閥工作正常。否則應(yīng)檢修。6、 接通空調(diào)開關(guān)后或轉(zhuǎn)動轉(zhuǎn)向盤時，如果發(fā)動機轉(zhuǎn)速沒有變化，說明怠速自動控制系統(tǒng)有故障，應(yīng)檢修。7、 把曲軸箱強制通風閥軟管夾緊，如果發(fā)動機轉(zhuǎn)速隨之下降，說明曲軸箱強制通風閥在怠速時開度過大，應(yīng)檢修。4.2.5發(fā)動機怠速時上下波動1】故障現(xiàn)象：怠速時發(fā)動機轉(zhuǎn)速不斷地上下波動。2】故障原因：1、 節(jié)氣門位置傳感器安裝調(diào)整不當，在怠

16、。2、 按規(guī)定程序重新檢查調(diào)整發(fā)動機的初始怠速。3、 檢查怠速控制閥是否工作正常。拔下怠速控制閥線束插頭，若發(fā)動機轉(zhuǎn)速沒有變化，則說明怠速控制閥不工作，應(yīng)更換2。5 怠速控制系統(tǒng)5.1怠速控制系統(tǒng)功能怠速控制（ISC）已經(jīng)成為發(fā)動機集中控制系統(tǒng)的基本控制內(nèi)容之一。怠速控制的目的是在保證發(fā)動機排放要且運轉(zhuǎn)穩(wěn)定的前提下，盡量使發(fā)動機的怠速轉(zhuǎn)速保持最低，以降低怠速時的燃油消耗量。電控噴射式發(fā)動機在怠速工況時，空氣通過節(jié)氣門縫隙或旁通節(jié)氣門的怠速空氣道進入發(fā)動機，并由空氣流量計（或進氣絕對壓力傳感器）對進氣量進行控制，電控燃油噴射系統(tǒng)（EFI）則根據(jù)各傳感器信號控制噴油量，保證發(fā)動機的怠速運轉(zhuǎn)。怠速控

17、制系統(tǒng)的功能是根據(jù)發(fā)動機的工作溫度和負載，由ECU自動控制怠速工況下的空氣供給量，維持發(fā)動機以穩(wěn)定怠速運轉(zhuǎn)。如圖5-1。(a) (b) 圖5-1 怠速進氣量控制方法 a)節(jié)氣門直動式 b)旁通空氣式 1節(jié)氣門 2進氣管 3節(jié)氣門操縱臂 4執(zhí)行元件 5怠速空氣道5.2怠速控制系統(tǒng)的組成怠速控制系統(tǒng)主要由傳感器、ECU、和執(zhí)行元件三大部分組成，如圖5-2所示。傳感器的功用是檢測發(fā)動機的運行工況的負載設(shè)備的工作狀況，ECU根據(jù)各種傳感器的輸入信號確定一個怠速運轉(zhuǎn)的目標轉(zhuǎn)速，控制執(zhí)行元件的工作，以調(diào)節(jié)進氣量，使發(fā)動機的怠速轉(zhuǎn)速達到所確定的目標轉(zhuǎn)速。到進氣管 圖5-2 發(fā)動機怠速控制系統(tǒng)結(jié)構(gòu)圖在怠速控制

18、系統(tǒng)中，ECU需要根據(jù)節(jié)氣門位置信號和車速信號確認怠速工況，只有在節(jié)氣門全關(guān)、車速為零時，ECU控制的怠速系統(tǒng)才起作用。如圖5-3。 圖5-3 ECU控制簡圖1冷卻液溫度 2壓縮機S W 3液力變矩器負荷信號4比 較 5節(jié)氣門全閉信號 6車速信號 7目標轉(zhuǎn)速 5.3怠速控制的方法措施怠速控制的實質(zhì)就是對怠速工況下的進氣量進行控制。在發(fā)動機集中控制系統(tǒng)中，控制怠速進氣量的方法可分為兩種基本類型：節(jié)氣門直動式和旁通空氣式。節(jié)氣門直動式通過執(zhí)行元件改變節(jié)氣門的最小開度來控制怠速進氣量，而旁通空氣怠速控制系統(tǒng)中，設(shè)有旁通節(jié)氣門的怠速空氣道，由執(zhí)行元件控制流經(jīng)怠速空氣道的空氣量。目前應(yīng)用比較廣泛的是旁通

19、空氣式怠速控制系統(tǒng)。按執(zhí)行元件的類型不同，旁通空氣式怠速控制系統(tǒng)又分步進電動型、旋轉(zhuǎn)電磁閥型、占空比控制電磁閥型、開關(guān)型等。怠速控制的方法及執(zhí)行元件的類型因車而異，目前應(yīng)用較多的是步進電動機控制的旁通空氣式怠速控制系統(tǒng)。不同車型的怠速控制系統(tǒng)，其控制內(nèi)容也不完全相同，控制內(nèi)容通常包括：起動控制、暖機控制（快怠速控制）、負荷變化控制、反饋控制和學習控制等。6 結(jié) 論隨著汽車經(jīng)濟的發(fā)展，汽車產(chǎn)業(yè)已成為我國五大支柱產(chǎn)業(yè)之一，關(guān)系到國家經(jīng)濟的安全和可持續(xù)發(fā)展，但中國的汽車發(fā)展史比較晚、起步晚、技術(shù)實力弱等因素。使我國汽車整體質(zhì)量保證不先進。問題多且故障復(fù)雜多變。為了能提高和改變維修行業(yè)人員的維修技術(shù)水

20、平和能力，能在正常的維修保養(yǎng)，以及在汽車出現(xiàn)各種問題能科學地、快捷地、準確無誤地為車主解決無后顧之憂！本文從我國汽車現(xiàn)狀出發(fā)，提出了解決微型車怠速不良和控制措施問題的整體思路和方法。對解決汽車在怠速問題方面的理論和實際問題方面，以及提高汽車維修行業(yè)人員操縱科學性、正規(guī)性等方面有一定幫助。但本文有不足之處或遺留問題。如是否存在例外情況或本論文尚未和難以解決或解釋的問題，也可請各位老師提出進一步研究本課題的建議。參考文獻1 譚本忠.汽車故障排解思路與實例.北京：機械工業(yè)出版社，2008.10（2009.7重?。?2 呂傳章.汽車維修與檢測診斷.北京：人民出版社，2001.7 3 張西振.汽車發(fā)動機

31、 The solider gave the old man a handmade saddle when they bid farewell. The story inspired Nasun to write Carved Saddle, a song that later became one of his most popular numbers. Now, every year, Nasun recruits young singers and dancers for the troupe. The troupe has also designed a new repertoire,

32、which is mostly based on the daily lives of Mongolian people, especially the lives of nomadic families, and has combined contemporary musical elements with folk songs of the region.

The Huachen Auctions also set a special session of photographs under the condition of large-scale decli

It followed a couple years of hushed excitement as Chinese fans were fed tidbits about their proud concubine who was supposed to conquer the hi

44、gh ground of the North American market. Zhen Huan is, of course, the title character of The Legend of Zhen Huan, a 2011 television series that swept China off its feet and later took other Asian countries by storm. Two years ago, it was reported that HBO, a premium cable service headquartered in the

45、 United States, was going to air it in North America after some modification. Now, a condensed version that provides English subtitles but no dubbing has finally been made available on Netflix for online streaming. This version, highly anticipated as a milestone in China's cultural foray oversea

46、s, has been widely panned by its home audience. Retitled Empresses in the Palace, the American version has been shortened from its original 76 episodes at 45 minutes each, to six 90-minute episodes. The quick pacing threw off many native viewers, who are accustomed to a more leisurely daytime-soap-s

47、tyle narrative rhythm. (Chinese TV stations would run two or three episodes every day.) I did not finish the full-length version and found the truncated one not difficult to follow. What's lost, I believe, are the interesting setups and pauses that illuminate the Chinese art of storytelling. Muc

48、h of the plot is still there. It is the flavor that was sacrificed. The American edition uses the framework of the Empress Dowager in her senior years reminiscing at the beginning and the end of each episode, hinting at what's to come and recapping the key points. This device, not used in the or

49、iginal, is culturally understandable but artistically mediocre. What puzzles me is the two new songs for the opening and end credits. They were written in English, but sung by Chinese with an uncomfortable accent. They were obviously designed to appeal to an English-speaking base, but do not jibe wi

50、th the Chinese dialogue. Speaking of the dialogue, the English translation, picked apart by some Chinese, is too literal for my taste. I can imagine a typical American hit by a flurry of royal ranks, addresses and greetings, even multiple names and titles for the same person. The first half hour mus

I see the choice of verbatim translation as an effort for conveying exotica. It is fairly competent, with no error that I could dete

But whether inside or outside China, the temptation to sell it for the differences is just too great. Sure, the sumptuou

53、s sets and costumes are a big attraction, but the narrative technique has becomehow shall I put it?a bit anglicized, which is necessary for cultural export. Judging by the responses, this legend, which, contrary to the claim of the English trailer, is totally fictitious, has departed from China but

54、not yet landed on American shores. I am a big fan of Ralph Waldo Emerson's essay titled Self-Reliance. If you've not yet read it, I strongly encourage you to do so. In this essay, the venerable Emerson talks about eschewing the trappings of society and finding one's own path. He urges th

55、e reader to find rectitude and lead a moral life. He professes that, only by being self reliant, as opposed to relying on the government and being dictated to by society, can one begin leading a decent and purposeful life. He avers that such a life is the only life worth living. I agree with him. Th

56、is essay was written during a time of social upheaval in America, and it is rather odd that Emerson authored it, as he was a part of the upper crust of society at the time. It just so happened that he looked around him, at the indolence and the wantonness of the people in his circle; he wondered how in the world he came to belong there. Indeed his penning and publishing this essay caused his excommunication fro
