第8 课 换气过程
内燃机工作循环的一个基本部分是新鲜空气的进入与废气的排出。这就是换气过程。扫气是指用新鲜空气吹出废气。充气是指将新鲜空气充入气缸以备压缩。
至于增压,是在一定压力下把大量空气吹入气缸。老式柴油机采用“自然换气”—在大 气压下吸入新鲜空气。通过在吸气管和气缸之间采用合适的压气机增加充气密度,使进入每 个工作冲程的空气重量增加,因此可燃烧更多的燃油,相应的,每缸输出功率增加。在大多 数现代柴油机上,采用废气涡轮增压实现空气密度的增加。在涡轮增压装置中,一个由柴油 机排气驱动的涡轮直接和离心压气机相连。无论是四冲程机还是二冲程机均可增压。应当注 意,增压对非增压柴油机而言,并非只是设备的增加。增压柴油机必须能经受所增加的压力 及所产生的热负荷。
对换气过程而言,进入气缸的空气压力高于排气总管的压力十分必要。由于废气涡轮增 压器在低转速下不能提供足够的空气,就二冲程柴油机而言,通常配备一台电动辅助鼓风机。高增压发动机使用串联(多级)涡轮增压。增压后的空气通过冷却来增加空气的密度。涡轮风机或涡轮增压器是在同一根轴相对的两端装废气涡轮和压气机。压气机和涡轮之 间彼此密封。
在新充的新鲜空气被压缩之前,每个气缸充分地驱除废气十分必要,否则新充新鲜空气 将被循环的残余废气污染。而且,若新充空气因与废气混合与热的缸壁及活塞接触而被加热,则循环的温度会毫无必要地增加。
在四冲程柴油机中,从进气阀打开到排气阀关闭,其间有一个适度的重叠。在重叠期间 流过气缸的空气流产生有益的冷却效果。这将有助于增加容积效率,并确保循环温度较低,而且还使作用在涡轮叶片上的废气温度相对较低。而在二冲程柴油机中,这一重叠受到柴油 机设计特点的限制,进排气的轻微混合确实存在。
低速二冲程柴油机有多种不同的扫气方式。无论哪一种都是从向下运动的活塞打开进 气口开始至向上运动的活塞关闭进气口为止。扫气空气的流动线路取决于柴油机气口的形状 设计以及排气布置。通常有三种基本的扫气方式:横流、回流及直流扫气。17
在横流扫气中,进气直接上行,驱赶前面的废气,然后,废气下行,从扫气口排出。在回流扫气中,进气经活塞头上部,朝缸盖方向上行,进气前的废气被迫下行。从位于 进气口上方的排气口排出。
在直流扫气中,进气从气缸下端进入,从顶部排出。气缸顶部的出口可以是排气口,也 可以是大的排气阀。
各种扫气系统各有利弊。横流扫气系统需安装活塞裙以防止当活塞在冲程顶部时(上止 点)空气或废气的逸出。回流扫气的低温进气和高温废气流过临近的气口,会对缸套材料产 生温差问题。直流扫气是最有效的扫气,但需安装对置活塞或在气缸盖上安装排气阀。三种 扫气均使气口成一定的角度,以使进气产生旋转,并引导空气按适当的路线流动。应该强调 的是,对置活塞低速柴油机已不再生产,而在大多数新机型中,均使用顶升排气阀。实际使用中有两种截然不同的增压方法,定压增压和脉冲增压。现在,定压增压被广泛 用于低速二冲程柴油机。目前,尽管定压增压在提高燃油经济性的同时极大地简化了排气管 的布置而被广泛采用,但也曾在一段时间内,几乎所有四冲程柴油机都采用脉冲增压。__
第五篇:新概念英语第二册课后练习答案lesson8
新概念英语第二册课后习题答案详解Lesson 8 练习答案 Key to written exercises 1.关键句型练习答案
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.难点练习答案
A 1 believes 2 was 3 tries B Sentences 2, 3 and 5 3.多项选择题答案
1.d根据课文的头一句和最后一句,只有d.是正确答案,其他3个选择都与课文内容不符合。
2.b根据课文第6-7行I like gardens too, but I do not like hard work可以推测b.是正确答案,其他3个选择都与事实不符合。
3.ba.larger garden 前面没有冠词a,不合乎语法;c.large garden 前面也缺少冠词a,d.largest garden中最高级前面应该有定冠词the,而且在两者相比时也不能使用最高级。
所以只有b.a large garden 最符合语法。
4.a本句需要比较级形式。B.more hard 中的hard 是单音节词,其比较形式是在词尾加-er;c.more hardly 中hardly(几乎不。。。)词意思不对;d.hardier 中原形hardy 是表示“强壮的”与课文不符合; 只有a.harder 最符合比较级形式。
5.ca.by, b.for , d.from 都不能同比较级连用,只有c.than 才可以和比较级连用。
6.c应该选同前一句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 有语法错误,也同前一句意思不符合;d.He likes有语法错误,缺少宾语; 只有c.He likes them 意思最接近,没有语法错误。
7.ba.in , c.for, d.by 都不符合语法,在意思上也讲不通。只有b.of 才能使句子的意思完整,也合乎语法。
8.ba.wins(获胜,获奖)做及物动词时,它后面的宾语一般不是人,而应是wind the game/race等;c.gains(获利,赚得)后面的宾语也不是人;d.earns(挣得,获得)后面的直接宾语也不应该是人;只有b.beats有“(在竞赛中)打败/战胜/取胜”的意思,而且beat 后面的宾语可以是人,所以选b.9.a只有选a.grow 才能使这个句子同前面的句子意思相同。Grow 可以做及物动词也可以做不及物动词。Grow做及物动词时,意思是“种植,栽培”,如前面的句子Joe grows more flowers.Grow做不及物动词,意思是“生长,产生”这个句子若选grow, More flowers grow in his garden(他的花园里生长更多的花)同前面句子意思最接近。而b.grow tall, c.grow up, d.grow big意思都不够准确。
10.d只有选d.interested 这个句子在意思上才讲得通。Be interestedin„.是固定短语(对„„感兴趣),主语一般是人。a.interesting(有趣的)做表语的时候主语应该是物,如前一句Joe’sgarden is interesting;b.interest(n.兴趣,利益)不能做表语; c.interestingly(有趣地)也不能做表语。
11.ba.a hard work 不符合语法,因为work 作“工作”讲时是不可数名词,不能在它前面加不定冠词a;c.hard job 也不符合语法,因为job 是可数名词,前面应该加不定冠词a;d.hardly a job 在意思上讲不通,不符合题目意思;只有b.a hard job(一项艰苦的工作)最合乎语法和题目意思。
12.ba.very(非常)丰富不符合题目意思,它也不能放到句尾;c.and 放在句尾没有任何意义;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,它可以放在谓语动词前也可以放在句尾,所以选b.
