第一章汽车总论 1)Today’s average car contains more than 15,000 separate, individual parts that must work together. These parts can be grouped into four major categories: body, engine, chassis and electrical equipment 。P1 现在的车辆一般都由15000多个分散、独立且相互配合的零部件组成。这些零部件主要分为四类：车身、发动机、底盘和电气设备。 2)The engine acts as the power unit. The internal combustion engine is most common: this obtains its power by burning a liquid fuel inside the engine cylinder. There are two types of engine: gasoline (also called a spark-ignition engine) and diesel (also called a compression-ignition engine). Both engines are called heat engines; the burning fuel generates heat which causes the gas inside the cylinder to increase its pressure and supply power to rotate a shaft connected to the power train. P3 发动机作为动力设备，常见的类型是内燃机，其原理是通过发动机缸内的液体燃料燃烧而产生能量。发动机可分为两类：汽油机（点燃式）和柴油机（压燃式），都属于热力发动机。燃料燃烧产生热量使缸内气压上升，产生的能量驱动轴旋转，并传递给动力传动系。 第二章内燃机 1)Power train system: conveys the drive to the wheels 2)Steering system: controls the direction of movement 3)Suspension system: absorbs the road shocks 4)Braking system: slows down the vehicle P4 传动系把发动机输出的扭矩传递给驱动轮。传动系包括离合器（对应机械变速器）或液力变矩器（对应液力自动变速器）、变速器、驱动轴、主减速器、差速器和驱动桥。 5)Drum brakes have a drum attached to the wheel hub, and braking occurs by means of brake shoes expanding against the inside of the drum. With disc brakes, a disc attached to the wheel hub is clenched between two brake pads. P6 鼓式制动器的制动鼓和轮毂连接，制动蹄张开压紧制动鼓内侧从而产生制动。在盘式制动器上，连着轮毂的制动盘被紧紧夹在两个制动块之间。 1)Linking the piston by a connecting rod to a crankshaft causes the gas to rotate the shaft through half a turn.The power stroke"uses up"the gas,so means must be provided to expel the burnt gas and recharge the cylinder with a fresh petrol-air mixture:this control of gas movement is the duty of the valves;An inlet valve allows the mixture to enter at the right time and an exhaust valve lets out the burnt gas after the gas has done its job . P10 活塞通过连杆和曲轴连接，使得气体带动曲轴旋转半圈。作功冲程耗尽了所有的气体，这样就必须采取相应的措施排出废气并且向气缸内充入新的可燃混合气：气体的运动由气门来控制。进气门使可燃混合气在恰当的时刻进入气缸，排气门使燃烧后的废气排出气缸。 2)The spark-ignition engine is an internal-combustion engine with externally supplied in ignition,which converts the energy cntained in the fuel to kinetic energy.The cycle of operations is spread over four piston strokes. To complete the full cycle it takes two revolutions of the crankshaft. P11 火花点火式发动机是由外部提供点火的内燃机，从而将含在燃料内的能量转化成动能。发动机的一个工作循环分布在活塞的四个行程中，一个完整的工作循环曲轴需要转动两圈。 3)The oil pump in the lubricating system draws oil from the oil pan and sends it to all working parts in the engine. The oil drains off and runs down into the pan. Thus,there is constant circulation of oil between the pan and the working parts of the engine. P15

第一课迎战卡米尔号飓风 1小约翰。柯夏克已料到，卡米尔号飓风来势定然凶猛。就在去年8月17日那个星期天，当卡米尔号飓风越过墨西哥湾向西北进袭之时，收音机和电视里整天不断地播放着飓风警报。柯夏克一家居住的地方一—密西西比州的高尔夫港——肯定会遭到这场飓风的猛烈袭击。路易斯安那、密西西比和亚拉巴马三州沿海一带的居民已有将近15万人逃往内陆安全地带。但约翰就像沿海村落中其他成千上万的人一样，不愿舍弃家园，要他下决心弃家外逃，除非等到他的一家人一—妻子詹妮丝以及他们那七个年龄从三岁到十一岁的孩子一一眼看着就要灾祸临头。 2为了找出应付这场风灾的最佳对策，他与父母商量过。两位老人是早在一个月前就从加利福尼亚迁到这里来，住进柯夏克一家所住的那幢十个房间的屋子里。他还就此征求过从拉斯韦加斯开车来访的老朋友查理?希尔的意见。 3约翰的全部产业就在自己家里(他开办的玛格纳制造公司是设计、研制各种教育玩具和教育用品的。公司的一切往来函件、设计图纸和工艺模具全都放在一楼)。37岁的他对飓风的威力是深有体会的。四年前，他原先拥有的位于高尔夫港以西几英里外的那个家就曾毁于贝翠号飓风(那场风灾前夕柯夏克已将全家搬到一家汽车旅馆过夜)。不过，当时那幢房子所处的地势偏低，高出海平面仅几英尺。“我们现在住的这幢房子高了23英尺，，’他对父亲说，“而且距离海边足有250码远。这幢房子是1915年建造的。至今还从未受到过飓风的袭击。我们呆在这儿恐怕是再安全不过了。” 4老柯夏克67岁．是个语粗心慈的熟练机械师。他对儿子的意见表示赞同。“我们是可以严加防卫。度过难关的，”他说?“一但发现危险信号，我们还可以赶在天黑之前撤出去。” 5 为了对付这场飓风，几个男子汉有条不紊地做起准备工作来。自米水管道可能遭到破坏，他们把浴盆和提俑都盛满水。飓风也可能造成断电，所以他们检查r手提式收音机和手电筒里的电池以及提灯里的燃料油。约翰的父亲将一台小发电机搬到楼下门厅里．接上几个灯泡。并做好把发电机与电冰箱接通的准备。 6那天下午，雨一直下个不停．乌云随着越来越猛的暴风从海湾上空席卷而来。全家早早地用r晚餐。邻居中一个丈夫去了越南的妇女跑过来。问她和她的两个孩子是否能搬进柯夏克家躲避风灾：另一个准备向内陆带转移的邻居也跑来问柯夏克家能否替他照看一下他的狗。 7不到七点钟，天就黑了．，狂风暴雨拍打着屋子。约翰让大儿子和大女儿上楼去取来被褥和枕头给几个小一点的孩子。他想把全家人都集中在同一层楼上。“不要靠近窗户!”他警告说，担心在飓风巾震破的玻璃碎片会飞来伤人。风凶猛地咆哮起来?屋子开始漏雨了……那雨水好像能穿墙透壁，往屋里直灌。一家人都操起拖把、毛巾、盆罐和水桶，展l开了一场排水战。到八点半钟，电没有了。柯夏克老爹便启动了小发电机。 8风的咆哮声压倒了一切。房子摇晃着，起居室的天花板一块块掉下来。楼上一个房问的法兰西式两用门砰地一声被风吹开了。楼下的人还听到楼上其他玻璃窗破碎时发出的劈劈啪啪的响声。积水已经漫到脚踝上了。 9随后，前门开始从门框上脱落。约翰和查理用肩膀抵住¨，但一股水浪冲击过来。撞开了大门，把两人都掀倒在地板上。发电机泡在水里，电灯熄灭了。查理舔了舔嘴唇，对着约翰大喊道：“这回可真是大难临头了。这水是成的。”海水已经漫到屋子跟前?积水仍不断上涨。

About car engine Of all automobile components,an automobile engie is the most complicated assembly with dominant effects on the function of an autombile.So, the engine is generally called the"heat"of an automobile. 在汽车的所有部件中，汽车发动机是最复杂的组件，其对整车性能有着决定性的作用。因而发动机往往被称作发动机的“心脏”。 There are actually various types of engines such as electric motors,stream engines,andinternal combustion engines.The internal combustion engines seem to have almost complete dominance of the automotive field.The internal combustion engine,as its name indicates,burns fuel within the cylinders and converts the expanding force of the combustion into rotary force used to propel the vehicle. 事实上，按动力来源分发动机有很多种，如电动机、蒸汽机、外燃机等。然而内燃机似乎在发动机领域有着绝对的统治地位。就像其字面意思一样，内燃机的染料在气缸内燃烧，通过将燃烧产生气体的膨胀力转换成转动力来驱动发动机前进。 Engine is the power source of the automobile.Power is produced by the linear motion of a piston in a cylinder.However,this linear motion must be changed into rotary motion to turn the wheels of cars or trucks.The puston attached to the top of a connecting rod by a pin,called a piston pin or wrist pin.The bottom of the connecting rod is attached to the crankshaft.The connecting rod transmits the up-and-down motion of the piston to the crankshaft,which changes it into rotary motion.The connecting rod is mounted on the crankshaft with large bearings called rod bearing.Similar bearings, called main bearings,are used to mount the crankshaft in the block. 发动机是整部车的动力来源。能量来自于活塞在气缸内的（往复）直线运动。然而这种（往复）直线运动必须要转换成旋转运动才能驱动车轮。活塞与连杆通过一个销来连接，这个销称为活塞销。连杆的下部连接于曲拐。连杆把活塞的上下往复运动传递给曲拐，从而将往复直线运动转变成旋转运动。连杆和曲拐的连接使用大的轴承，称之为连杆轴承，类似的轴承也用于将曲轴连接到机体，称之为主轴承。 They are generally two different types of cooling system:water-cooling system and air-cooling system.Water-cooling system is more common.The cooling medium, or coolant, in them is either water or some low-freezing liquid, called antifreeze.A water-cooling system consists of the engine water jacket, thermostat, water pump, radiator, radiator cap, fan, fan drive belt and neccessary hoses. 主要有两种类型的冷却系统：水冷和风冷。水冷系统更为普遍。系统所用冷却介质或是冷却液常委水或其他低凝固点液体，称为抗凝剂。一个完整的水冷系统包括机体水套，节温器，水泵，散热器，散热器罩，风扇，风扇驱动皮带和必需的水管。 A water-cooling system means that water is used as a cooling agent to circulate through the engine to absorb the heat and carry it to the radiator for disposal.The ebgine is cooled mainly through heat transfer and heat dissipation.The heat generated by the mixture burned in the engine must be transferred from the iron or aluminum cylinder to the waterin the water jacket.The outside of the water jacket dissipates some of the heat to the air surrounding it, but most of the heat is carried by the cooling water to the radiator for dissipation.When the coolant temperature in the system reaches 90°,the termostat valve open fully, its slanted edge shutting off

Unit1 发动机是汽车的心脏。汽车引擎的目的是将燃料转化为能量使汽车移动。最简单的方法是在发动机内部燃烧燃料。,因此,汽车发动机是一种内燃机,缸内燃烧燃料和燃烧的扩张力量转换成旋转力用来驱动汽车。 这里有多种类型的内燃机分为往复式和旋转式引擎;火花式点火或压缩式点火发动机;代用燃料发动机。 往复式发动机 最熟悉的组合是往复式,火花点火,四冲程汽油发动机,如图1-1a所示。现代汽车通常是由水冷活塞式内燃机,安装在汽车的前面,它的力量可以被传送到前轮，传到后轮,或所有车轮轮。一些汽车使用风冷式发动机,但这些通常效率不及液冷式。往复式发动机的另一个主要类型是柴油发动机(如图果1-1b所示),这是使用重型车辆，如卡车，公共汽车和少数家庭轿车。柴油和汽油发动机一般采用四冲程循环。 转子式发动机 转子式内发动机,也叫汪克尔发动机,由德国的Felix~Wankel在1954年开发的,可以提供一种低废气排放和大规模生产的可行性的发动机来替代往复式发动机机。在这种发动机中，三面转子在燃烧室的自由空间内旋转使其随着转子转动压缩和膨胀,见图1 - 2。燃料被吸入、压缩和被点火系统的点燃。膨胀的气体带动转子然后废气排出,如图1 - 3所示。旋转式引擎没有气门,活塞,连杆,往复部件,或曲轴。它提高了马力,基本上不会有震动,但它的油耗是高于传统活塞式发动机。 代用燃料汽车 内燃机消耗大量的石油,并造成严重的空气污染,因此,其他类型的燃料和非常规引擎被研究和发展。 可替代燃料汽车(AFV)是一种用常见的油箱的柔性燃料车辆，设计一种在不同混合的无铅汽油与乙醇或双燃料汽车运行，一种可使用替代燃料和传统燃料。一种高科技车辆(A TV)结合了新引擎,动力传动机构,传动系系统显著提高燃油经济性。最理想的替代燃料发动机燃烧燃料比传统汽油内燃机更为简洁,但仍然能够使用现有的加油站。 混合动力电动车 混合动力汽车或者混合电动汽车(HEV)(如图1 - 4所示),是由两个或两个以上的能源,其中之一是电力可以高英里每加仑，低排放。有两种类型的混合动力汽车,串联和并联式。在串联式电动汽车中,车辆动力所有动力来自同一个源头。例如,一个电动马达驱动的汽车电池和内燃机驱动发电机给电池充电。在并联混合动力,电力是通过这两个路径,电动机和内燃机驱动车辆。这一点,可能有助于电力汽车的电动发动机空转和加速度。内燃机巡航时,驱动传动系和给电池充电。 在当前生产混合动力车发动机和电动马达连接,同样的传播协助下电动引擎可以更小。
高级英语第二册段落翻译
《高级英语》段落翻译（英译汉）及参考答案 01 But what is strange about these people is their invisibility. For several weeks, always at about the same time of day, the file of old women had hobbled past the house with their firewood, and though they had registered themselves on my eyeballs I cannot truly say that I had seen them. Firewood was passing -- that was how I saw it. It was only that one day I happened to be walking behind them, and the curious up-and-down motion of a load of wood drew my attention to the human being beneath it. Then for the first time I noticed the poor old earth-coloured bodies, bodies reduced to bones and leathery skin, bent double under the crushing weight. 然而这些人的真正奇特之处还在于他们的隐身的特性。一连几个星期，每天几乎在同一时候总有一队老妪扛着柴草从我房前蹒跚走过。虽然他们的身影以映入我的眼帘，但老实说，我并不曾看见她们。我所看见的是一捆捆的柴草从屋外掠过。直到有一天我碰巧走在她们身后时，堆柴草奇异的起伏动作才使我注意到原来下面有人。这才第一次看见那些与泥土同色的可怜老妪的躯体——枯瘦的只剩下皮包骨头、被沉重的负荷压得弯腰驼背的躯体。 02．This kind of thing makes one's blood boil, whereas-- on the whole -- the plight of the human beings does not. I am not commenting, merely pointing to a fact. People with brown skins are next door to invisible. Anyone can be sorry for the donkey with its galled back, but it is generally owing to some kind of accident if one even notices the old woman under her load of sticks. 这样的事令人气愤，相反地-----总的来说----人的困境却没有引起同样的反响。我不是在发表议论，我仅仅是说明一个事实。褐种人近于无形。谁都会同情一只磨伤脊梁的驴子。但往往要有某种偶然因素，一个人甚至才会注意到压在柴禾下面的老妪。 03. When you walk through a town like this -- two hundred thousand inhabitants of whom at least twenty thousand own literally nothing except the rags they stand up in-- when you see how the people live, and still more how easily they die, it is always difficult to believe that you are walking among human beings. All colonial empires are in reality founded upon this fact. The people have brown faces--besides, there are so many of them! Are they really the same flesh as your self? Do they even have names? Or are they merely a kind of undifferentiated brown stuff, about as individual as bees or coral insects? They rise out of the earth，they sweat and starve for a few years, and then they sink back into the nameless mounds of the graveyard and nobody notices that they are gone. And even the graves themselves soon fade back into the soil. 当你穿行也这样的城镇——其居民20万中至少有2万是除开一身聊以蔽体的破衣烂衫之外完全一无所有——当你看到那些人是如何生活，又如何动辄死亡时，你永远难以相信自己是行走在人类之中。实际上，这是所有的殖民帝国赖以建立的基础。这里的人都有一张褐色的脸，而且，人数如此之多！他们真的和你意义同属人类吗？难道他们也会有名有姓吗？也许他们只是像彼此之间难以区分的蜜蜂 或珊瑚虫一样的东西。他们从泥土里长出来，受苦受累，忍饥挨饿过上几年，然后有被埋在那一个个无名的小坟丘里。谁也不会注意到他们的离去。就是那些小坟丘本身也过不了很久便会变成平地。

Fuel Supply System of Gasoline Engine(UNIT SEVEN) All the gasoline engines have substantially identical fuel systems and run on a mixture consisting of fuel vapor and air. The fuel system comprises the units designed to store, clear and deliver fuel, the units intended to clean air and a unit for preparing a mixture from fuel vapor and air. In a fuel system different components are used to supply fuel from the fuel tank into the engine cylinder. Some of the important components are fuel tank, fuel pump, fuel filter, carburetor, intake manifold and fuellines or tubes connecting the tank, pump and the carburetor. The fuel tank is a fuel container used for storing fuel. It is made of sheet metal. It is attached to the vehicle frame with metal traps and is located at the rear of the vehicle. They are mounted in a boot or boot-floor pan in case of front-engined cars and small commercial vehicles. In order to strengthen the tank as well as to prevent surging of fuel when the vehicle rounds a curve of suddenly stops, baffle plates are attached to the inside of the tank. A cap is used to close the filler opening of the tank. The fuel line is attached at or near the bottom of the tank with a filtering element placed at the connection. The other components of the fuel tank are the fuel gauge sending unit, a vent pipe, receiving unit. To prevent the dirt and water from entering the luggage compartment, a sealing strip is fitted between the fuel tank and boot floor pan. Moreover to limit the transmission of frame distortion to the tank giving rise to squeaking as the metal parts get rubbed together, rubber or felt pads are often fitted between the mountings and the tank. Provision is also made against drumming of the tank by these mountings. The tank may be placed at the side of the chassis frame for convenience in case of large commercial vehicles. The length of the connecting lines or tubes from the tank to the carburetor is also restricted by this at the same time. A porous filter is attached to the outlet lines. By drawing fuel from the tank through the filter, any water in the bottom of the tank as well as any dirt into the fuel gathers on the surface of the filter. To keep the fuel always under atmospheric pressure, the filter pipe or tank is vented. In order to prevent dirt in the fuel from entering the fuel pump or carburetor, fuel filters and screens are used in the fuel system. If the dirt is not removed from the fuel, the normal operation of these units will be prevented. The engine performance will also be reduced.

INTERNAL COMBUSTION ENGINE 引擎燃烧室 1. principle of operation 原理 Engine and power : Engine is used to produce power. The chemical energy in fuel is converted to heat by the burning of the fuel at a controlled rate. This process is called combustion. If engine combustion occurs with the power chamber. ,the engine is called internal combustion engine. If combustion takes place outside the cylinder, the engine is called an external combustion engine. Engine used in automobiles are internal combustion heat engines. Heat energy released in the combustion chamber raises the temperature of the combustion gases with the chamber. The increase in gas temperature causes the pressure of the gases to increase. The pressure developed within the combustion chamber is applied to the head of a piston to produce a usable mechanical force, which is then converted into useful mechanical power. 译: 引擎和能量: 引擎为汽车提供能量，燃料的化学能通过燃烧，转化为热能，这个过程叫燃烧。假如燃烧在燃烧室，这样的发动机叫内燃机。假如燃烧在气缸外，这样的发动机叫外燃机。 用在汽车上的一般是内燃机，热能在燃烧室释放，燃烧室气体温度升高。气体温度的升高使气体的压力曾加，燃烧室内的高压气体作用在活塞头部产生可以利用的化学能，化学能转化为机械能。 Engine T erms : Linking the piston by a connecting rod to a crankshaft causes the gas to rotate the shaft through half a turn. The power stroke “uses up” the gas , so means must be provided to expel the burnt gas and recharge the cylinder with a fresh petrol-air mixture :this control of gas movement is the duty of the valves ;an inlet valve allows the new mixture to enter at the right time and an exhaust valve lets out the burnt gas after the gas has done its job. Engine terms are : TDC(Top Dead Center):the position of the crank and piston when the piston is farther away from the crankshaft. BDC(Bottom Dead Center):the position of the crank and piston when the piston is nearest to the crankshaft. Stroke : the distance between BDC and TDC; stroke is controlled by the crankshaft. Bore : the internal diameter of the cylinder. Swept volume : the volume between TDC and BDC Engine capacity : this is the swept volume of all the cylinder e.g. a four-stroke having a capacity of two liters(2000cm) has a cylinder swept volume of 50cm. Clearance volume: the volume of the space above the piston when it is at TDC. Compression ratio = (swept vol + clearance vol)\(clearance vol) Two-stroke : a power stroke every revolution of the crank.

一，21-27 1.We' re 23 feet above sea level. 2. The house has been here since 1915, and no hurricane has ever caused any damage to it. 3. We can make the necessary preparations and survive the hurricane without much damage. 4. Water got into the generator and put it out. It stopped producing electricity, so the lights also went out. 5. Everybody go out through the back door and run to the cars. 6. The electrical systems in the car had been put out by water. 7. As John watched the water inch its way up the steps, he felt a strong sense of guilt because he blamed himself for endangering the whole family by deciding not to flee inland. 8. ()h God, please help us to get through this storm safely. 9. Grandmother Koshak sang a few words alone and then her voice gradually grew dimmer and stopped. 10. Janis displayed rather late the exhaustion brought about by the nervous tension caused by the hurricane. 柯夏克家的屋顶一被掀走，约翰就高喊道：“快上楼一一到卧室里去!数数孩子。”在倾盆大雨中，大人们围成一圈，让孩子们紧紧地挤在中间。柯夏克老奶奶哀声切切地说道：“孩子们，咱们大家来唱支歌吧!”孩子们都吓呆了，根本没一点反应。老奶奶独个儿唱了几句，然后她的声音就完全消失了。 客厅的壁炉和烟囱崩塌了下来。弄得瓦砾横飞。眼看他们栖身的那间卧室电有两面墙壁行将崩塌，约翰立即命令大伙：“进电视室去!”这是离开风头最远的一个房间。 约翰用手将妻子搂了一下。詹妮丝心里明白了他的意思。由于风雨和恐惧，她不住地发抖。她一面拉过两个孩子紧贴在自己身边，一面默祷着：亲爱的上帝啊，赐给我力量，让我经受住必须经受的一切吧。她心里怨恨这场飓风。我们一定不会让它得胜。 柯夏克老爹心中窝着一团火，深为自己在飓风面前无能为力而感到懊丧。也说不清为什么，他跑到一问卧室里去将一只杉木箱和一个双人床垫拖进了电视室。就在这里，一面墙壁被风刮倒了，提灯也被吹灭。另外又有一面墙壁在移动，在摇晃。查理.希尔试图以身子撑住它，但结果墙还是朝他这边塌了下来，把他的背部也给砸伤了。房子在颤动摇晃，已从地基上挪开了25英尺。整个世界似乎都要分崩离析了。 “我们来把床垫竖起来!”约翰对父亲大声叫道。“把它斜靠着挡挡风。让孩子们躲到垫子下面去，我们可以用头和肩膀把垫子支撑起来。 大一点的孩子趴在地板上，小一点的一层层地压在大的身上，大人们都弯下身子罩住他们。地板倾斜了。装着那一窝四只小猫的盒子从架上滑下来，一下子就在风中消失了。斯普琪被从一个嵌板书柜顶上刮走而不见踪影了。那只狗紧闭着双眼，缩成一团。又一面墙壁倒塌了。水拍打着倾斜的地板。约翰抓住一扇还连在壁柜墙上的门，对他父亲大声叫道：“假若地板塌了，咱们就把孩子放到这块门板上面。”
