ExplanationRear-wheeldrivefromafrontenginewasthemethodusedformanyyears.Somemanufacturershavecontinueditsuse,BMWforexample.Alongpropellershaftfromthegearboxtothefinaldrive,whichispartoftherearaxle,isthemainfeatureThepropellershafthasuniversaljointstoallowforsuspensionmovement.Thislayouthassomeadvantages:1）Weighttransferstothereardrivingwheelswhenaccelerating.2）Complicatedconstantuniversaljoints,suchasusedbyfront-wheeldrivevehicles,arenotneeded.译文：前置发动机、后轮驱动是多年来使用的方法。一些制造商，例如宝马，继续使用此方法。作为后轴的一部分，从变速箱到最终传动的长传动轴是主要特征。传动轴具有万向节，以允许悬架运动。这种布局有一些优点：1）加速时重量转移到后驱动轮。2）不需要复杂的恒定万向节，例如前轮驱动车辆使用的万向节。Text ExplanationFour-wheeldrivecombinesallthegoodpointsmentionedabovebutmakesthevehiclemorecomplicatedandthereforeisexpensive.Themaindifferencewithfour-wheeldriveisthatanextragearboxknownasatransferboxisneededtolinkthefront-andrear-wheeldrive.译文：四轮驱动结合了上述所有优点，但使车辆更加复杂，因此价格昂贵。四轮驱动的主要区别在于需要一个额外的变速箱，称为分动箱，用于连接前轮驱动和后轮驱动。Text ExplanationTypesoflightvehiclecanrangefromsmalltwo-seatsportscarstolargepeoplecarriersorsportsutilityvehicles(SUVs).Alsoincludedintherangearelightcommercialvehiclessuchasvansandpick-uptrucks.Itishardtocategorizeacarexactlyasthereareseveralagreedsystemsinseveraldifferentcountries.译文：轻型车辆的类型范围可以从小型双座跑车到大型人员运输车或运动型多功能车（SUV）。该系列还包括轻型商用车辆，如货车和皮卡车。很难对汽车进行分类，因为在几个不同的国家/地区有多个商定的系统。Text ExplanationTherearenginedesignhasnotbeenverypopularbutitwasusedforthebestsellingcarofalltime:theVWBeetle.Theadvantagesarethatweightisplacedontherearwheels,givinggoodgrip,andthepowerunitanddrivecanbealloneassembly.Onedownsideisthatlessroomisavailableforluggageinthefront.Thebiggestproblemisthathandlingisaffectedbecauseoflessweightonthesteeredwheels.Flat-typeenginesarethemostcommonchoiceforthistypeofvehicle.译文：后置发动机设计并不是很受欢迎，但它被用于有史以来最畅销的汽车：大众甲壳虫。优点是重量放在后轮上，提供良好的抓地力，动力单元和驱动器可以是一个组件。一个缺点是前面的行李箱空间较小。最大的问题是操纵受到影响，因为转向轮的重量较轻。平板式发动机是这类车辆最常见的选择。请指出图1-14所示汽车部件中文名称及其相应英文名称。Passage

ExplanationThisareaismadeupofthebraking,steeringandsuspensionsystemsaswellasthewheelsandtires.Hydraulicpressureisusedtoactivatethebrakestoslowdownorstopthevehicle.Rotatingdiscsaregrippedbetweenpadsoffrictionlining.Thehandbrakeusesamechanicallinkagetooperateparkingbrakes.Bothfrontwheelsarelinkedmechanicallyandmustturntogethertoprovidesteeringcontrol.译文：该区域由制动、转向和悬挂系统以及车轮和轮胎组成。液压用于启动制动器以减慢或停止车辆。制动盘夹在摩擦衬垫之间。手制动器使用机械连杆来操作驻车制动器。两个前轮都是机械连接，必须转动才能提供转向控制。Text ExplanationTheengineflywheelandclutchcoverareboltedtogethersotheclutchalwaysrotateswiththeengine,andwhentheclutchpedalisraiseddriveispassedtothegearbox.Agearboxisneededbecauseanengineproducespoweronlywhenturningquitequickly.Thegearboxallowsthedrivertokeeptheengineatitsbestspeed.Whenthegearboxisinneutral,powerdoesnotleaveit.译文：发动机飞轮和离合器盖用螺栓固定在一起，因此离合器始终随发动机一起旋转，当离合器踏板升起时，驱动力传递到变速箱。需要一个变速箱，因为发动机只有在转速很快时才会产生动力。变速箱允许驾驶员将发动机保持在最佳速度。当变速箱处于空档时，动力不会消失。Text ExplanationAstartermotortakesenergyfromthebatterytocrankoverandstarttheengine.Electricalcomponentsarecontrolledbyarangeofswitches.Electronicsystemsusesensorstodetectconditionsandactuatorstocontrolavarietyofthingsinfact,onmodernvehicles,almosteverything.译文：起动马达从电池获取能量以起动并启动发动机。电气元件由一系列开关控制。电子系统使用传感器来检测条件和执行器，以控制各种动作。事实上，在现代车辆上，几乎所有东西都离不开电子系统。请指出图1-19所示工作套装中文名称及其相应英文名称。Passage

ExplanationThecrankandconnectingrodmechanismisthemainmechanismofareciprocatingenginefortransformingthermalenergyintomechanicalenergy.Ittransformsthereciprocatinglinearmotionofthepistonunderactionofpressureintothecircularmotionofthecrankshafttodeliverpowertotheexternalcomponents.译文：曲柄连杆机构是往复活塞式发动机将热能转换为机械能的主要机构，其功用是将燃气作用在活塞顶上的压力转变为曲轴旋转运动而对外输出动力。Text ExplanationCrankandconnectingrodmechanismconsistsofthepistonandconnectingrodgroupandthecrankshaftandflywheelgroup.Thepistonandconnectingrodgroupincludesmainlythepiston,pistonrings,pistonpin,andconnectingrod.Thecrankshaftandflywheelgroupincludesmainlythecrankshaft,flywheel,pulley,andtiminggear.译文：曲柄连杆机构由活塞连杆组和曲轴飞轮组两部分组成。活塞连杆组主要包括活塞、活塞环、活塞销、连杆等零部件。曲轴飞轮组包括曲轴、飞轮、带轮、正时齿轮等零部件。Text Explanation.Whentheengineisrunning,thepressureofgasesproducedfromfuelburningisdirectlyappliedtothepistoncrown.Thepistonishencedriventoreciprocatealongastraightline.Thepowerappliedbythepistonisdeliveredviathepistonpinandtheconnectingrodtothecrankshaft.Thereciprocatinglinearmotionofthepistonistransformedintothecircularmotionofthecrankshaft.Largeportionofthepowerproducedbytheengineisdeliveredtothedrivelineviatheflywheelinstalledattherearendofthecrankshaft.Thepoweristhendeliveredtothedrivewheelsofthevehicle,viathedriveline.Anotherportionofthepowerproducedbytheengineisusedtodrivetheaccessoriesoftheengineitselfandothersystems,viathegearandthepulleyinstalledatthefrontendofthecrankshaft.Text Explanation译文：发动机工作过程中，燃料燃烧产生的气体压力直接作用在活塞顶上，推动活塞作往复直线运动。活塞作用力经活塞销、连杆传给曲轴，将活塞的往复运动转换为曲轴的旋转运动。发动机产生的动力大部分由曲轴后端的飞轮传给底盘的传动系统，再经过传动系统传给汽车的驱动轮；还有一部分动力通过曲轴前端的齿轮和带轮驱动发动机自身的其他机构和系统。请指出图2-2所示发动机配气机构部件中文名称及其相应英文名称。Passage
