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.

The filter is either fitted inside the fuel tank and pump or operates as a separate unit connected between the fuel tank and pump or between pump and carburetor into the fuel lines. Carburetors are also provided filter screens while a filter element is provided in the fuel tank.

The fuel filter used is generally a sediment bowl made of glass or metal and a strainer screen. When the fuel drawn from the tank passes through the filter (through the bowl and strainer screen), particles of dirt and water settle in the bottom of the bowl. In certain vehicles, a separate filter either of the disk or ceramic type is used. It is either located between the fuel pump and carburetor or in the fuel line.

For connecting the fuel tank to the fuel pump, metallic tubes or synthetic rubber hose used are called fuel lines. They are usually positioned with metallic clips along the frame side members. The tubing or fuel lines are also used to connect fuel pump to the carburetor. In order to absorb vibration as well as prevent breakage of the fuel lines, a short flexible line is used between the fuel pump and the tank.

In order to meter and caution the driver of the motor vehicle about the quantity of fuel consumed and left in the tank, a fuel gauge is used. It is generally fitted on dash board for easy reading of the fuel. It is usually a balancing coil type having construction similar to that of an oil gauge. It is generally electrically operated.

It consists of a sending unit mounted on the fuel tank and a receiving unit having a caliberated gauge mounted on the instrument panel.

A sending unit consists of a float controlled thermostat or variable resistor. With a float and the float arm extending into the fuel tank, the whole unit is mounted on it. The level of fuel in the tank varies the position of the float. The amount of electrical resistance within the variable resistor for controlling the amount of current sent to receiving unit on the instrument panel is determined by the float position.

The receiving unit mounted on the dash board indicates the amount of fuel in the tank on a caliberated gauge by the amount of current received from the sending unit.

On modern automobiles, two types of fuel gauges; thermostatic type and an electromagnetic type are used.

In order to prevent the rapid wear and tear of engine operating components causing reduced performance air cleaner is fitted to the carburetor air intake, it is mounted on the

carburetor air-horn for trapping dirt. Before entering the carburetor, the air must pass through it.

To reduce the noise produced by the air rushing into the carburetor, a silencing chamber is built into the air cleaner. In case the engine misfires back through the carburetor, it acts as the flame arrestor.

There are in general three types of the air cleaners used in modern automobiles. They are (a) oil bath cleaner (b) oil-wetted mesh air cleaner (c) dry type air cleaner. The first two are also known as heavy duty air cleaner while the third is known as light duty air cleaner.

Fuel pumps are the devices used to supply fuel from the fuel tank to the carburetor. There are in general two main types of fuel pumps used in automobiles. They are main types of fuel pumps used in automobiles. They are (a) mechanical fuel pump (b) electric fuel pump.

Lesson One: The Time Message Elwood N, Chapman 新的学习任务开始之际，千头万绪，最重要的是安排好时间，做时间的主人。本文作者提出了7点具体建议，或许对你有所启迪。 1 Time is tricky. It is difficult to control and easy to waste. When you look a head, you think you have more time than you need. For Example,at the beginning of a semester, you may feel that you have plenty of time on your hands, but toward the end of the term you may suddenly find that time is running out. You don't have enough time to cover all your duties (duty), so you get worried. What is the answer? Control! 译：时间真是不好对付，既难以控制好，又很容易浪费掉，当你向前看时，你觉得你的时间用不完。例如，在一个学期的开始，你或许觉得你有许多时间，但到学期快要结束时，你会突然发现时间快用光了，你甚至找不出时间把所有你必须干的事情干完，这样你就紧张了。答案是什么呢？控制。 2 Time is dangerous. If you don't control it, it will control you. I f you don't make it work fo r you, it will work against you. So you must become the master of time, not its servant. As a first-year college student, time management will be your number one Problem. 译：时间是危险的，如果你控制不了时间，时间就会控制你，如果你不能让时间为你服务，它就会起反作用。所以，你必须成为时间的主人，而不是它的奴仆，作为刚入学的大学生，妥善安排时间是你的头等大事。 3 Time is valuable. Wasting time is a bad habit. It is like a drug. The more time you waste,the easier it is to go on wasting time. If seriously wish to get the most out of college, you must put the time message into practice. 译：时间是珍贵的，浪费时间是个坏习惯，这就像毒品一样，你越浪费时间，就越容易继续浪费下去，如果你真的想充分利用上大学的机会，你就应该把利用时间的要旨付诸实践。 Message1. Control time from the beginning. 4 Time is today, not tomorrow or next week. Start your plan at the Beginning of the term. 译：抓紧时间就是抓紧当前的时间，不要把事情推到明天或是下周，在学期开始就开始计划。 Message2. Get the notebook habit. 5 Go and buy a notebook today, Use it to plan your study time each day. Once a weekly study plan is prepared, follow the same pattern every week with small changes. Sunday is a good day to make the Plan for the following week.

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

大学英语Unit 1 课文翻译

学外语 学习外语是我一生中最艰苦也是最有意义的经历之一。虽然时常遭遇挫折，但却非常有价值。 我学外语的经历始于初中的第一堂英语课。老师很慈祥耐心，时常表扬学生。由于这种积极的教学方法，我踊跃回答各种问题，从不怕答错。两年中，我的成绩一直名列前茅。 到了高中后，我渴望继续学习英语。然而，高中时的经历与以前大不相同。以前，老师对所有的学生都很耐心，而新老师则总是惩罚答错的学生。每当有谁回答错了，她就会用长教鞭指着我们，上下挥舞大喊：“错！错！错！”没有多久，我便不再渴望回答问题了。我不仅失去了回答问题的乐趣，而且根本就不想再用英语说半个字。 好在这种情况没持续多久。到了大学，我了解到所有学生必须上英语课。与高中老师不同，大学英语老师非常耐心和蔼，而且从来不带教鞭！不过情况却远不尽如人意。由于班大，每堂课能轮到我回答的问题寥寥无几。上了几周课后，我还发现许多同学的英语说得比我要好得多。我开始产生一种畏惧感。虽然原因与高中时不同，但我却又一次不敢开口了。看来我的英语水平要永远停步不前了。 直到几年后我有机会参加远程英语课程，情况才有所改善。这种课程的媒介是一台电脑、一条电话线和一个调制解调器。我很快配齐了必要的设备并跟一个朋友学会了电脑操作技术，于是我每周用5到7天在网上的虚拟课堂里学习英语。 网上学习并不比普通的课堂学习容易。它需要花许多的时间，需要学习者专心自律，以跟上课程进度。我尽力达到课程的最低要求，并按时完成作业。 我随时随地都在学习。不管去哪里，我都随身携带一本袖珍字典和笔记本，笔记本上记着我遇到的生词。我学习中出过许多错，有时是令人尴尬的错误。有时我会因挫折而哭泣，有时甚至想放弃。但我从未因别的同学英语说得比我快而感到畏惧，因为在电脑屏幕上作出回答之前，我可以根据自己的需要花时间去琢磨自己的想法。突然有一天我发现自己什么都懂了，更重要的是，我说起英语来灵活自如。尽管我还是常常出错，还有很多东西要学，但我已尝到了刻苦学习的甜头。 学习外语对我来说是非常艰辛的经历，但它又无比珍贵。它不仅使我懂得了艰苦努力的意义，而且让我了解了不同的文化，让我以一种全新的思维去看待事物。学习一门外语最令人兴奋的收获是我能与更多的人交流。与人交谈是我最喜欢的一项活动，新的语言使我能与陌生人交往，参与他们的谈话，并建立新的难以忘怀的友谊。由于我已能说英语，别人讲英语时我不再茫然不解了。我能够参与其中，并结交朋友。我能与人交流，并能够弥合我所说的语言和所处的文化与他们的语言和文化之间的鸿沟。

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

新编大学英语（第二版）第一册阅读文参考译文 Unit One 以生命相赠 1 炸弹落在了这个小村庄里。在可怕的越南战争期间，谁也不知道这些炸弹要轰炸什么目标，而他们却落在了一所有传教士们办的小孤儿院内。 2 传教士和一两个孩子已经丧生，还有几个孩子受了伤，其中有一个小女孩，8岁左右，她的双腿被炸伤。 3 几小时后，医疗救援小组到了。救援小组由一名年轻的美国海军医生和一名同样年轻的海军护士组成。他们很快发现有个小女孩伤势严重。如果不立即采取行动，显然她就会因失血过多和休克而死亡。 4 他们明白必须给小女孩输血，但是他们的医药用品很有限，没有血浆，因此需要相配血型的血。快速的血型测定显示两名美国人的血型都不合适，而几个没有受伤的孤儿却有相配的血型。 5 这位医生会讲一点越南语，忽视会讲一点法语，但只有中学的法语水平。孩子们不会说英语，只会说一点法语。医生和护士用少得可怜的一点共同语言，结合大量的手势，努力向这些受惊吓的孩子们解释说，除非他们能输一些血给自己的小伙伴，否则她将必死无疑。接着问他们是否有人愿意献血来救小女孩。 6 对医生和护士的请求，孩子们（只是）瞪大眼睛，一声不吭。此时小病人生命垂危。然而，只有这些受惊吓的孩子中有人自愿献血，他们才能够得到血。过了好一会儿，一只小手慢慢地举了起来，然后垂了下去，一会儿又举了起来。 7 “噢，谢谢，”护士用法语说。“你叫什么名字？” 8 “兴，”小男孩回答道。 9 兴很快被抱到一张床上，手臂用酒精消毒后，针就扎了进去。在整个过程中，兴僵直地躺着，没有出声。 10 过了一会儿，他发出了一声长长的抽泣，但立即用那只可以活动的手捂住了自己的脸。 11 “兴，疼吗？”医生问。 12 兴默默地摇了摇头，但一会儿忍不住又抽泣起来，并又一次试图掩饰自己的哭声。医生又问是不是插在手臂上的针弄疼了他，兴又摇了摇头。

新标准大学综合英语2 unit1 课文翻译

NUIT1 大学已经不再特别了 有这么一种说法：“要是你能记得20世纪60年代的任何事情，你就没有真正经历过那段岁月。”对于在大麻烟雾中度过大学时光的那些人，这话可能是真的。但是，20世纪60年代有一件事人人都记得，那就是：上大学是你一生中最激动人心、最刺激的经历。 20世纪60年代，加州的高校把本州变成了世界第七大经济实体。然而，加州大学的主校园伯克利分校也以学生示威、罢课以及激进的政治氛围而著名。1966年，罗纳德?里根竞选加州州长，他问加州是否允许“一所伟大的大学被喧闹的、唱反调的少数人征服。”自由派人士回答说，大学之所以伟大正是因为它们有能力容忍喧闹的、唱反调的少数人。 在欧洲的大学校园里，大学生以新的姿态和激情投入到争取自由和正义的事业中去，大规模的社会主义或共产主义运动引发了他们与当权者之间日益升级的暴力冲突。许多抗议是针对越南战争的。可是在法国，巴黎大学的学生与工会联盟，发动了一场大罢工，最终导致戴高乐总统辞职。 20世纪60年代大学生活的特点并不仅仅是激进的行动。不论在什么地方，上大学都意味着你初次品尝真正自由的滋味，初次品尝深更半夜在宿舍或学生活动室里讨论人生意义的滋味。你往往得上了大学才能阅读你的第一本禁书，看你的第一部独立影人电影，或者找到和你一样痴迷吉米?亨德里克斯或兰尼?布鲁斯的志同道合者。那是一段难以想象的自由时光，你一生中最无拘无束的时光。 可如今那份激情哪儿去了？大学怎么了？现在，政治、社会和创造意识的觉醒似乎不是凭借大学的助力，而是冲破其阻力才发生的。当然，一点不假，高等教育仍然重要。例如，在英国，布莱尔首相几乎实现了到2010年让50％的30岁以下的人上大学的目标（即使愤世嫉俗的人会说，这是要把他们排除在失业统计数据之外）。不过，大学教育已不再是全民重视的话题了。如今，大学被视为人们急于逃离的一种小城镇。有些人辍学，但大多数已经有些麻木，还是坚持混到毕业，因为离开学校实在是太费事了。 没有了20世纪60年代大学生所发现的令人头脑发热的自由气氛，如今的大学生要严肃得多。英国文化协会最近做了一项调查，研究外国留学生在决定上哪所大学时所考虑的因素。这些因素从高到低依次是：课程质量、就业前景、学费负担、人身安全问题、生活方式，以及各种便利。大学已变成实现目的的手段，是在就业市场上增加就业几率的一个机会，上大学本身不再是目的，不再是给你提供一个机会，让你暂时想象一下：你能够改变世界。 童年与大学之间的距离已缩小了，大学与现实世界之间的距离也缩小了。其中的一个原因可能和经济有关。在一个没有保障的世界里，现在的许多孩子依赖父母资助的时间比以前的孩子更长。21世纪的学生大学毕业后根本无法自立门户，因为那太昂贵了。另一个可能的原因是通讯革命。儿子或女儿每学期往家里打一两回电话的日子一去不复返了。如今，大学生通过手机与父母保持着脐带式联系。至于寻找痴迷无名文学或音乐的同道好友，没问题，我们有互联网和聊天室来帮助我们做到这一点。

Unit 1 Changes in the Way We Live 在美国，不少人对乡村生活怀有浪漫的情感。许多居住在城镇的人梦想着自己办个农场，梦想着靠土地为生。很少有人真去把梦想变为现实。或许这也没有什么不好，因为，正如吉姆·多尔蒂当初开始其写作和农场经营双重生涯时所体验到的那样，农耕生活远非轻松自在。但他写道，自己并不后悔，对自己作出的改变生活方式的决定仍热情不减。 Mr. Doherty Builds His Dream Life Jim Doherty 有两件事是我一直想做的――写作与务农。如今我同时做着这两件事。作为作家，我和E·B·怀特不属同一等级，作为农场主，我和乡邻也不是同一类人，不过我应付得还行。在城市以及郊区历经多年的怅惘失望之后，我和妻子桑迪终于在这里的乡村寻觅到心灵的满足。 这是一种自力更生的生活。我们食用的果蔬几乎都是自己种的。自家饲养的鸡提供鸡蛋，每星期还能剩余几十个出售。自家养殖的蜜蜂提供蜂蜜，我们还自己动手砍柴，足可供过冬取暖之用。 这也是一种令人满足的生活。夏日里我们在河上荡舟，在林子里野餐，骑着自行车长时间漫游。冬日里我们滑雪溜冰。我们为落日的余辉而激动。我们爱闻大地回暖的气息，爱听牛群哞叫。我们守着看鹰儿飞过上空，看玉米田间鹿群嬉跃。 但如此美妙的生活有时会变得相当艰苦。就在三个月前，气温降

到华氏零下30度，我们辛苦劳作了整整两天，用一个雪橇沿着河边拖运木柴。再过三个月，气温会升到95度，我们就要给玉米松土，在草莓地除草，还要宰杀家禽。前一阵子我和桑迪不得不翻修后屋顶。过些时候，四个孩子中的两个小的，16岁的吉米和13岁的埃米莉，会帮着我一起把拖了很久没修的室外厕所修葺一下，那是专为室外干活修建的。这个月晚些时候，我们要给果树喷洒药水，要油漆谷仓，要给菜园播种，要赶在新的小鸡运到之前清扫鸡舍。 在这些活计之间，我每周要抽空花五、六十个小时，不是打字撰文，就是为作为自由撰稿人投给报刊的文章进行采访。桑迪则有她自己繁忙的工作日程。除了日常的家务，她还照管菜园和蜂房，烘烤面包，将食品装罐、冷藏，开车送孩子学音乐，和他们一起练习，自己还要上风琴课，为我做些研究工作并打字，自己有时也写写文章，还要侍弄花圃，堆摞木柴、运送鸡蛋。正如老话说的那样，在这种情形之下，坏人不得闲――贤德之人也歇不了。 我们谁也不会忘记第一年的冬天。从12月一直到3月底，我们都被深达5英尺的积雪困着。暴风雪肆虐，一场接着一场，积雪厚厚地覆盖着屋子和谷仓，而室内，我们用自己砍伐的木柴烧火取暖，吃着自家种植的苹果，温馨快乐每一分钟。 开春后，有过两次泛滥。一次是河水外溢，我们不少田地被淹了几个星期。接着一次是生长季节到了，一波又一波的农产品潮涌而来，弄得我们应接不暇。我们的冰箱里塞满了樱桃、蓝莓、草莓、芦笋、豌豆、青豆和玉米。接着我们存放食品罐的架子上、柜橱里也开始堆

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.
