第四篇：輪機(jī)英語 翻譯lesson8

第8 課 換氣過程

內(nèi)燃機(jī)工作循環(huán)的一個(gè)基本部分是新鮮空氣的進(jìn)入與廢氣的排出。這就是換氣過程。掃氣是指用新鮮空氣吹出廢氣。充氣是指將新鮮空氣充入氣缸以備壓縮。

至于增壓，是在一定壓力下把大量空氣吹入氣缸。老式柴油機(jī)采用“自然換氣”—在大 氣壓下吸入新鮮空氣。通過在吸氣管和氣缸之間采用合適的壓氣機(jī)增加充氣密度，使進(jìn)入每 個(gè)工作沖程的空氣重量增加，因此可燃燒更多的燃油，相應(yīng)的，每缸輸出功率增加。在大多 數(shù)現(xiàn)代柴油機(jī)上，采用廢氣渦輪增壓實(shí)現(xiàn)空氣密度的增加。在渦輪增壓裝置中，一個(gè)由柴油 機(jī)排氣驅(qū)動(dòng)的渦輪直接和離心壓氣機(jī)相連。無論是四沖程機(jī)還是二沖程機(jī)均可增壓。應(yīng)當(dāng)注 意，增壓對(duì)非增壓柴油機(jī)而言，并非只是設(shè)備的增加。增壓柴油機(jī)必須能經(jīng)受所增加的壓力 及所產(chǎn)生的熱負(fù)荷。

對(duì)換氣過程而言，進(jìn)入氣缸的空氣壓力高于排氣總管的壓力十分必要。由于廢氣渦輪增 壓器在低轉(zhuǎn)速下不能提供足夠的空氣，就二沖程柴油機(jī)而言，通常配備一臺(tái)電動(dòng)輔助鼓風(fēng)機(jī)。高增壓發(fā)動(dòng)機(jī)使用串聯(lián)(多級(jí))渦輪增壓。增壓后的空氣通過冷卻來增加空氣的密度。渦輪風(fēng)機(jī)或渦輪增壓器是在同一根軸相對(duì)的兩端裝廢氣渦輪和壓氣機(jī)。壓氣機(jī)和渦輪之 間彼此密封。

在新充的新鮮空氣被壓縮之前，每個(gè)氣缸充分地驅(qū)除廢氣十分必要，否則新充新鮮空氣 將被循環(huán)的殘余廢氣污染。而且，若新充空氣因與廢氣混合與熱的缸壁及活塞接觸而被加熱，則循環(huán)的溫度會(huì)毫無必要地增加。

在四沖程柴油機(jī)中，從進(jìn)氣閥打開到排氣閥關(guān)閉，其間有一個(gè)適度的重疊。在重疊期間 流過氣缸的空氣流產(chǎn)生有益的冷卻效果。這將有助于增加容積效率，并確保循環(huán)溫度較低，而且還使作用在渦輪葉片上的廢氣溫度相對(duì)較低。而在二沖程柴油機(jī)中，這一重疊受到柴油 機(jī)設(shè)計(jì)特點(diǎn)的限制，進(jìn)排氣的輕微混合確實(shí)存在。

低速二沖程柴油機(jī)有多種不同的掃氣方式。無論哪一種都是從向下運(yùn)動(dòng)的活塞打開進(jìn) 氣口開始至向上運(yùn)動(dòng)的活塞關(guān)閉進(jìn)氣口為止。掃氣空氣的流動(dòng)線路取決于柴油機(jī)氣口的形狀 設(shè)計(jì)以及排氣布置。通常有三種基本的掃氣方式：橫流、回流及直流掃氣。17

在橫流掃氣中，進(jìn)氣直接上行，驅(qū)趕前面的廢氣，然后，廢氣下行，從掃氣口排出。在回流掃氣中，進(jìn)氣經(jīng)活塞頭上部，朝缸蓋方向上行，進(jìn)氣前的廢氣被迫下行。從位于 進(jìn)氣口上方的排氣口排出。

在直流掃氣中，進(jìn)氣從氣缸下端進(jìn)入，從頂部排出。氣缸頂部的出口可以是排氣口，也 可以是大的排氣閥。

各種掃氣系統(tǒng)各有利弊。橫流掃氣系統(tǒng)需安裝活塞裙以防止當(dāng)活塞在沖程頂部時(shí)(上止 點(diǎn))空氣或廢氣的逸出?；亓鲯邭獾牡蜏剡M(jìn)氣和高溫廢氣流過臨近的氣口，會(huì)對(duì)缸套材料產(chǎn) 生溫差問題。直流掃氣是最有效的掃氣，但需安裝對(duì)置活塞或在氣缸蓋上安裝排氣閥。三種 掃氣均使氣口成一定的角度，以使進(jìn)氣產(chǎn)生旋轉(zhuǎn)，并引導(dǎo)空氣按適當(dāng)?shù)穆肪€流動(dòng)。應(yīng)該強(qiáng)調(diào) 的是，對(duì)置活塞低速柴油機(jī)已不再生產(chǎn)，而在大多數(shù)新機(jī)型中，均使用頂升排氣閥。實(shí)際使用中有兩種截然不同的增壓方法，定壓增壓和脈沖增壓?，F(xiàn)在，定壓增壓被廣泛 用于低速二沖程柴油機(jī)。目前，盡管定壓增壓在提高燃油經(jīng)濟(jì)性的同時(shí)極大地簡化了排氣管 的布置而被廣泛采用，但也曾在一段時(shí)間內(nèi)，幾乎所有四沖程柴油機(jī)都采用脈沖增壓。__

第五篇：新概念英語第二冊(cè)課后練習(xí)答案lesson8

新概念英語第二冊(cè)課后習(xí)題答案詳解Lesson 8 練習(xí)答案 Key to written exercises 1．關(guān)鍵句型練習(xí)答案

A 1 Mary's handwriting is worse than Jane's.2 Caroline's handwriting is worse than Mary's and Jane's.3 Caroline's dress is/ was more expensive than Jane's.4 Mary's dress is/ was more expensive than Jane's and Caroline's.B ?has the most beautiful garden in our town?‘The Nicest Garden Competition’?garden is larger than Joe's?works harder than Joe and grows more flowers and vegetables?garden is more interesting?for the worst garden in the town!D 1 in 2 of 3 of 4 in 2．難點(diǎn)練習(xí)答案

A 1 believes 2 was 3 tries B Sentences 2, 3 and 5 3．多項(xiàng)選擇題答案

1.d根據(jù)課文的頭一句和最后一句，只有d.是正確答案，其他3個(gè)選擇都與課文內(nèi)容不符合。

2.b根據(jù)課文第6-7行I like gardens too, but I do not like hard work可以推測(cè)b.是正確答案，其他3個(gè)選擇都與事實(shí)不符合。

3.ba.larger garden 前面沒有冠詞a,不合乎語法；c.large garden 前面也缺少冠詞a,d.largest garden中最高級(jí)前面應(yīng)該有定冠詞the,而且在兩者相比時(shí)也不能使用最高級(jí)。

所以只有b.a large garden 最符合語法。

4.a本句需要比較級(jí)形式。B.more hard 中的hard 是單音節(jié)詞，其比較形式是在詞尾加-er;c.more hardly 中hardly(幾乎不。。。)詞意思不對(duì)；d.hardier 中原形hardy 是表示“強(qiáng)壯的”與課文不符合； 只有a.harder 最符合比較級(jí)形式。

5.ca.by, b.for , d.from 都不能同比較級(jí)連用，只有c.than 才可以和比較級(jí)連用。

6.c應(yīng)該選同前一句The writer is fond of garden 意思相近的句子。A.They like him意思同前一句相反； b.they like to him 有語法錯(cuò)誤，也同前一句意思不符合；d.He likes有語法錯(cuò)誤，缺少賓語； 只有c.He likes them 意思最接近，沒有語法錯(cuò)誤。

7.ba.in , c.for, d.by 都不符合語法，在意思上也講不通。只有b.of 才能使句子的意思完整，也合乎語法。

8.ba.wins(獲勝，獲獎(jiǎng))做及物動(dòng)詞時(shí)，它后面的賓語一般不是人，而應(yīng)是wind the game/race等；c.gains(獲利，賺得)后面的賓語也不是人；d.earns(掙得，獲得)后面的直接賓語也不應(yīng)該是人；只有b.beats有“（在競賽中）打敗/戰(zhàn)勝/取勝”的意思，而且beat 后面的賓語可以是人，所以選b.9.a只有選a.grow 才能使這個(gè)句子同前面的句子意思相同。Grow 可以做及物動(dòng)詞也可以做不及物動(dòng)詞。Grow做及物動(dòng)詞時(shí)，意思是“種植，栽培”，如前面的句子Joe grows more flowers.Grow做不及物動(dòng)詞，意思是“生長，產(chǎn)生”這個(gè)句子若選grow, More flowers grow in his garden(他的花園里生長更多的花)同前面句子意思最接近。而b.grow tall, c.grow up, d.grow big意思都不夠準(zhǔn)確。

10.d只有選d.interested 這個(gè)句子在意思上才講得通。Be interestedin?.是固定短語（對(duì)??感興趣），主語一般是人。a.interesting(有趣的)做表語的時(shí)候主語應(yīng)該是物，如前一句Joe’sgarden is interesting;b.interest(n.興趣，利益)不能做表語； c.interestingly(有趣地)也不能做表語。

11.ba.a hard work 不符合語法，因?yàn)閣ork 作“工作”講時(shí)是不可數(shù)名詞，不能在它前面加不定冠詞a；c.hard job 也不符合語法，因?yàn)閖ob 是可數(shù)名詞，前面應(yīng)該加不定冠詞a；d.hardly a job 在意思上講不通，不符合題目意思；只有b.a hard job(一項(xiàng)艱苦的工作)最合乎語法和題目意思。

12.ba.very(非常)豐富不符合題目意思，它也不能放到句尾；c.and 放在句尾沒有任何意義；b.also 和 d.either都有也的意思，但either只能用于否定句的句尾，also可以用于肯定句中，它可以放在謂語動(dòng)詞前也可以放在句尾，所以選b.
