【正文】 te, to only see a tiny bit of the place due to the crowds. Last year, 428 million tourists traveled in China over the weeklong holiday in October. Traveling during this period is a matter that needs thorough preparation. If you are short on time to plan the uping Golden Week it may not be a bad idea to avoid some of the most crowded places for now. There is always a place so fascinating that everyone yearns for. Arxan is a place like this. The beauty of Arxan is everlasting regardless of the changing of four seasons. Bestowed by nature, its spectacular seasonal landscape and mountains are just beyond word. Arxan is a crucial destination for the remended travelling route, China Inner Mongolia Arxan — Hailar — Manzhouli. It is also the joint of the four prairies across the SinoMongolian border, where people gravitate towards the exotic atmosphere mixed with Chinese, Russian, and Mongolia elements. As a historic site for the Yitian Battle, Arxan still embodies the spirit of Genghis Khan. Walking into Arxan, you will be amazed by a kaleidoscope of geous colors all the year round the Spring azaleas blooming red in the snow, the Summer sea wavering blue in the breeze, the Autumn leaves painted in yellow covering volcanic traces, and the Winter woods shining white on the vast alpine snowscape. Hinggan League Arxan city is situated in the far eastern area of Inner Mongolia Autonomous Region. Its full name Haren Arxan means hot holy water in the Mongolian language. Arxan is a tourism city in the northern frontier with a blend of large forest, grand prairies, vast snowfield, heaven lake cluster, thermium, as well as volcanic cluster. It is a rare and unique ecotourism base filled with healthy sunshine, clean air and unspoiled green. Nestled close to the country39。s Day. More and more young Chinese people begin to celebrate this day in a very similar way as that in western countries. Fewer people than ever will gaze at the heavens on Saturday to pick out the two stars shining bright on either side of the Milky Way, that is, if people even know on which day Qixi falls. There are ready reminders dotted about, in the form of big ads saying Sales on Chinese Valentine39。 我還要感謝培養(yǎng)我長(zhǎng)大含辛茹苦的父母，謝謝你們！ 最后，再次對(duì)關(guān)心、幫助我的老師和同學(xué)表示衷心地感謝。 （ 3）正是由于前面的學(xué)習(xí)總結(jié)，讓我對(duì)于 DHE 發(fā)動(dòng)機(jī)電控系統(tǒng)的維修有了一套完整的檢修方法。正常情況下，在 8s 內(nèi)擺動(dòng)的次數(shù)不得低于 10 次。 氧傳感器加熱器的供電電路與氧傳感器信號(hào)電路短路 (在傳感器本身內(nèi) )，從而導(dǎo)致加熱電壓進(jìn)入氧傳感器信號(hào)電路，造成信號(hào)電壓被提升 300mV。有時(shí)，盡管條件正常，加速滯后也很嚴(yán)重，甚至在氧 傳 15 感器并沒有徹底壞的情況下，汽車也從來沒有真正地跑得很好過。電路故障可用裝用工具 WDS 檢測(cè)故障碼，若有故障碼，噴油器或其控制電路故障。斷開二缸噴油器線束，測(cè)量噴油器電阻，阻值為 13Ω ，噴油器線圈正常。 更換汽油泵，然后再次測(cè)試汽油壓力， 390kpa 正常，熄火停放 2 分鐘油壓下降為 350kpa，正常。 、萬用表 汽車萬用表是一種高阻抗（≥ 10MΩ）數(shù)字多用表。 在應(yīng)用數(shù)據(jù)流，還應(yīng)熟悉電子燃油噴射系統(tǒng)的工作原理。 、檢測(cè)蓄電池電壓 用電壓表檢測(cè)蓄電池的工作電壓，其標(biāo)準(zhǔn)值為 12V。 裝上油壓表（安裝方法與靜態(tài)檢查時(shí)相同），啟動(dòng)發(fā)動(dòng)機(jī)后使發(fā)動(dòng)機(jī)怠速運(yùn)轉(zhuǎn)，然后從油壓調(diào)節(jié)器上拆下真空管并用塞子塞住管口，此時(shí)油壓表的讀數(shù)應(yīng)為 11 265～ 304Kpa。 、怠速抖動(dòng) 如果冷車怠速抖動(dòng)與熱車怠速抖動(dòng)同時(shí)存在，則首先排除熱車怠速抖動(dòng)故障。當(dāng) ECU 接 收到由各種傳感器送來的節(jié)氣門開度和發(fā)動(dòng)機(jī)轉(zhuǎn)速二個(gè)基本參數(shù)后，便立即通過內(nèi)存的三種頻譜圖查出對(duì)應(yīng)的基本噴油量、點(diǎn)火提前角和點(diǎn)火脈寬，另外再根據(jù)其它傳感器（如進(jìn)氣歧管壓力、進(jìn)氣溫度、水溫、爆震等）以及空擋起 動(dòng)、空調(diào)、動(dòng)力轉(zhuǎn)向等開關(guān)參數(shù)變化信號(hào)后，便對(duì)基本噴油量和點(diǎn)火提前角以及點(diǎn)火脈寬作出修正，從而使發(fā)動(dòng)機(jī)獲得最佳的運(yùn)轉(zhuǎn)工況、最好的動(dòng)力性和燃料經(jīng)濟(jì)性。 （ 2）點(diǎn)火信號(hào)輸出（ Spout）控制點(diǎn)火線圈負(fù)極的功率晶體管。燃油泵只供應(yīng)發(fā)動(dòng)機(jī)所需要的燃油量，這個(gè)燃油量是根據(jù)規(guī)定的系統(tǒng)壓力得出的。 25） r/min 壓縮比 :1 點(diǎn)火順序 1342 缸徑行程 mm mm 6 最大功率 (6000r/min) 105kw 最大扭矩 (4500r/min) 廢氣再循環(huán) 水冷 卻廢氣再循環(huán) 燃油種類 C913 號(hào)全合成無鉛汽油 C915 號(hào)福特專用無鉛汽油 點(diǎn)火系統(tǒng) 有分電器電子點(diǎn)火（ TFI） 燃油噴射 順序多點(diǎn)燃油噴射（ SFI） 、 發(fā)動(dòng)機(jī)的電控燃油噴射系統(tǒng) 電控燃油噴射系統(tǒng)簡(jiǎn)稱 EFI，它由燃料供給系統(tǒng)（簡(jiǎn)稱燃油系統(tǒng)）、進(jìn)氣系統(tǒng)和電子控制系統(tǒng) 3 個(gè)子系統(tǒng)組成。 5 2 福特蒙迪歐 DHE 發(fā)動(dòng)機(jī)簡(jiǎn)介 、 DHE 發(fā)動(dòng)機(jī)的結(jié)構(gòu)特點(diǎn) 蒙迪歐發(fā)動(dòng) 機(jī)是由美國(guó)福特公司與日本馬自達(dá)公司共同開發(fā)，分為 直列發(fā)動(dòng)機(jī)和 型發(fā)動(dòng)機(jī)。 關(guān)鍵詞： DHE 發(fā)動(dòng)機(jī) 電控系統(tǒng)結(jié)構(gòu) 工作原理 故障診斷 3 目 錄 1 前言 ..................................................................... 5 2 福特蒙迪歐 DHE 發(fā)動(dòng)機(jī)簡(jiǎn)介 ............................................... 6 、 DHE 發(fā)動(dòng)機(jī)統(tǒng)的結(jié)構(gòu)特點(diǎn) ................................ 6 、 DHE 發(fā)動(dòng)機(jī)主要技術(shù)參數(shù) ................................ 6 、 發(fā)動(dòng)機(jī)的電控燃油噴射系統(tǒng) ......................... 7 發(fā)動(dòng)機(jī)電控系統(tǒng)構(gòu)成與工作原理 ........................................ 7 、燃油供給系統(tǒng) .......................................... 7 、空氣供給系統(tǒng) .......................................... 7 、電控點(diǎn)火系統(tǒng) .......................................... 8 、電子控制系統(tǒng) .......................................... 8 、輔助設(shè)備 ..............
