汽车专业英语读译教程翻译UNIT 7 TEXT A

（6）Maintain correct viscosity (free flowing at all temperatures).保持正确的粘度（在所有温度下自由流动）。

When the brake fluid boils, it becomes vapor. A vapor can be compressed, but a liquid cannot be compressed. Pressing on the brake pedal will compress the vapor in the lines instead of transferring the pressure through the fluid. This can lead to partial or complete braking system failure, sometimes called brake pedal fade. Mountain driving puts increased duty on brakes and brake fluid. The boiling point drops at high altitude. This naturally increases the tendency towards vapor lock. In fact, vapor lock in the hydraulic braking system is the primary reason for brake pedal fade.当制动液沸腾时，它变成蒸汽。

可以压缩蒸汽，但不能压缩液体。

按压制动踏板将压缩管线中的蒸汽，而不是将压力传递通过流体。

这可能导致部分或完全制动系统故障，有时称为制动踏板褪色。

山地驾驶增加了刹车和制动液的使用。

沸点在高海拔下降。

这自然增加了气体锁定的趋势。

事实上，液压制动系统中的汽油锁是制动踏板褪色的主要原因。

1.These parts can be grouped into four major categories; body, engine, chassis and electrical system.2.The internal combustion engine is most common; this obtains its power by burning a liquid fuel inside the engine cylinder.3.The chassis includes the power train, steering, suspension, and braking systems.4. A power train can include a clutch for manual transmission or a torque converter for automatic transmission, a transmission, a drive shaft, final driveand differential gears and driving axles.5.Basic types are: leaf springs, coil springs and torsion bars.6. A basic ignition system consists of the battery, low-lension cables, the ignition coil, distributor, coil high-tension cable, spark plug cables and sparkplugs.7.The operating strokes are: induction stroke, compression stroke, power stroke, exhaust stroke.8.The major parts of engine are engine block, engine heads, pistons, connecting rods, crankshaft and valves.9.These systems are the fuel system, intake system, ignition system, cooling system, lubrication system and exhaust system.10.The dry clutch mechanism includes three basic parts: driving member, driven member and operating members.11.The spur gears are mounted on four shafts: primary shaft (input shaft), layshaft (countershaft), mainshaft, and reverse idler shaft.12.The three types of braking systems are in use today: service braking system, parking braking system and additional retarding-braking system.13.It has five basic parts: the receiver, expansion valve, evaporator, compressor, and condenser.14.The three normally adjustable angles are caster, camber, and toe.段落一．Elements of the Power TrainThe elements of the power train must meet the following requirements;1)enable driving away,2)convert torque and speed,3)enable different directions of rotation for driving forward and backward,4)transmit tractive and pushing forces,5)permit different rotational speeds of the drive wheels when cornering,6)guarantee optimum operation of the engine (or electric motor ) in terms of fuel consumption and exhaust emissions.Standstill, driving-away and power interruption are made possible by operation the clutch .During driving away, the clutch slips and bridges the difference in rotational speed between engine and power train. When different operating conditions call for a shift of gear, the clutch separates the power train during shifting.Engine torque and engine speed are converted in the transmission in accordance with the tractive-power demand of the vehicle. The transmission design is influenced by the position of the engine and driven axle. Overall conversion takes place usually in a manually shifted transmission with variable transmission ratios and in a final drive with a constant transmission ratio. Nowadays, positive-locking transmissions with toothed gears as the most important elements are of even greater significance than non-positive friction-type transmissions.Two types of toothed-gear transmission are predominant: spur-gear transmissions of the countershaft type as manually shifted transmissions, and planetary-gear transmissions as power-shift transmissions. In addition, transmissions permit the different directions of rotation required for driving forward and backward.Final drive turns the drive through 90°and reduces the speed of the drive by a set amount to the vehicle.The differential provides for the equalization of the different axle and wheel speeds when cornering and for uniform distribution of the drive torque.二.The Hydrodynamic Coupling1. Hydrodynamic CouplingConventionally, the hydrodynamic coupling, also known as the Fötttinger coupling, has an impeller and a turbine wheel with vanes that usually extend in the radial direction. The impeller is often expanded to form a housing which surrounds the turbine. Since, due to the absence of an inner ring, there is no possibility of diverting the oil flow, the turbine torque is equal to the pump torque;公式Therefore 公式The index number depends on the design, the vane angle and the degree of filling of the coupling. The main working area of an hydrodynamic coupling is at v=0.9.2. Hydrodynamic ConverterThe hydrodynamic converter, also known as the Trilok or Fötttinger converter, is capable of operating in two phases: with torque increase in the first phase, and as a hydrodynamic coupling in the second phase. The usual design has three impellers:1) The pump, which is connected to the engine, acts like a centrifugal pump to produce the flow energy of a fluid.2) The turbine, which is connected to the transmission input, converts the flow energy back into mechanical energy.3) The reactor between turbine and pump diverts the flow of the fluid.Thus, the torque output is higher than the pump torque input from the engine. The torque increaseμμ=Mt/Mp is all the higher, the greater the speed difference (slip）between the pump and turbine. Withυ=0, i.e. with the turbine braked to a standstill (stall point, drive-away point), torque conversion reaches its maximum value and falls virtually linearly with rising turbine speed to a torque ratio of 1:1 at the coupling point. Above the coupling point, the reactor, which is supported on the housing by a one-way clutch, runs, torque-free, in the flow. Thus, the converter is now a clutch without torque conversion.For automobiles, the vane geometries are such that, at the drive-away point, the maximum torque increase μA is between 2 and 2.5. The hydraulic efficiencyηhydr=υμis similar in the conversion range to the speed ratioμand reaches values around 97% at high speed.Fluid couplings form the input element of automatic transmissions (in conjunction with planetary-gear trains, clutches, brakes and one-way clutches) and also of manually shifted transmissions in the form converter and clutch unit.三．Constant-mesh TransmissionFig.3-6 illustrates the flow of torque through a typical constant-mesh transmission. This type uses helical or double helical gears which are always in mesh. The mainshaft gear wheels are mounted on bearings and when a gear is required the mainshaft gear is locked to the shaft by a dog clutch.Although the mechanical efficiency is lower the helical gears are quieter and any damage resulting from a bad gear change occurs to the dog teeth instead of the actual gear teeth.元素的力量训练动力传动的要素必须符合下列要求;1)使开车逃走,2)把转矩和速度,3)使不同方向的旋转带动向前和向后,四)推进传送叶轮力量,5)允许不同转速时的驱动轮转弯时,六)保证了优化运行的引擎(或电机)从油耗和尾气排放。

汽车工程专业英语全文翻译一当今的汽车一般都由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。

Body：车身Engine：发动机Brakes：制动器Power train ：传动系Steering：转向系Electrical：电器及电子设备Suspension：悬架Layout of a passenger car：乘用车总布置Layout of a commercial vehicle ：商用车总布置1.1 车身汽车车身是由车窗、车门、发动机罩和行李箱盖焊接在金属板外壳发动机发动机作为动力装置。

最常见的发动机气缸的排列方式称为发动机配置。

直列式发动机的汽缸呈一列布置。

这个设计创造了一个简单的发动机缸体铸造。

在车辆应用中，汽缸数一般是2-6 缸，汽缸中心线与水平面垂直。

当汽缸数增多时，发动机尺寸和曲轴就成为一个问题。

解决这个问题的办法就是采用V 形（汽缸呈两列布置，且两列气缸之间夹角为V 形）发动机。

这个设计使发动机尺寸和曲轴都变得更短且更坚硬。

前置发动机纵向安装，既可前轮驱动也可后轮驱动。

后置发动机是将发动机安装在后轮后面。

发动机可横置或纵置，一般情况下为后轮驱动。

1.4 电气系统电气系统为起动机、点火系统、照明灯具、取暖器提供电能。

该电平由一个充电电路维护。

1.4.1 充电充电系统为所有汽车电子元件提供电能。

充电系统主要包括：蓄电池，交流发电机，电压调节器，即通常是交流发电机上不可或缺的，充电警告或指示灯和金属丝连成一个完整电路。

蓄电池为起动提供电能 ,然后发动机工作，交流发电机就为所有的电子元件提供电能。

同时也给蓄电池充电即用来使发动机起动。

电压调节器有过充保护作用。

1.4.2 起动起动系统包括：蓄电池、电缆、起动机、飞轮和换向器。

起动时，有两个动作同时运行，该起动机齿轮与飞轮齿圈啮合，并起动电机，然后运行传输到发动机曲轴。

起动机电机将起动机安装在发动机缸体上并由电池供电。

When the throttle valve is opened, air flow through the air cleaner, through the air flow meter (on L type systems), past the throttle valve, and through a well tuned intake manifold runner to the intake valve .Air delivered to the engine is function of drive demand .As the throttle valve is opened further, more air is allowed to enter the engine cylinder.当节气门打开,空气通过空气滤清器,通过空气流量计(L型系统),经过节气门,并在进气歧管中经过良好的调整进入进气门。

空气被送到发动机是驾驶员要求的一种。

当节气门进一步打开时,允许更多的空气进入发动机汽缸。

Toyota engines use two different methods to measure intake air volume. The L type EFI system measures air flow directly by using an air flow meter. The D type EFI system measures air flow indirectly by monitoring the pressure in the intake manifold. 丰田发动机使用两种不同的方法来测量进气量。

L型EFI系统是通过空气流量计直接测量进气量的。

D型EFI系统通过监测进气歧管的压力间接测量进气量的。

The electronic control system consists of various engine sensors, electronic control unit (ECU), and various actuators.发动机的电子控制系统由传感器、电子控制单元(ECU)和各种执行机构。

汽车专业英语翻译Today's average car contains more than 15,000 separate, individual parts that must work together. These parts can grouped into four major categories: engine, body, chassis and electrical equipment.现代汽车有超过15000个零件组成，分成几个必须在一起工作的功能部分。

主要包括4个功能部分：引擎，车身，底盘和电控。

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 transmission.引擎为汽车提供能源。

一般是内燃机：通过在引擎缸内燃烧液体燃料获得能量。

引擎有两种：汽油机和柴油机。

两种引擎都叫热机。

About car engineOf 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。

第一单元发动机分类及工作原理课文A发动机的分类所有的汽车发动机都是内燃机（ICE),就是将燃油在气缸内进行燃烧，并将燃烧产生的膨胀压力转变成转动力，用来驱动汽车。

所以说，发动机是动力源, 并被认为是汽车的心脏。

汽车发动机根据工作方式分为往复式发动机和转子发动机：报据发动机燃烧的燃料分为汽油机和柴油机：根据发动机的气缸数量和气缸排列方式分为直列发动机、V型发动机、对置式发动机和W型发动机。

往复式发动机和转子发动机往复式发动机也称为活塞式发动机。

该发动机采用一个或多个活塞在气缸内上下运动或前后运动，将压力转变为转动动能传递给汽车驱动轮（见图1-1)。

往复式发动机广泛应用现代汽车上。

转子发动机是于1954年研发出来的。

如图1-2所示，在该发动机中，有个三角形的转子在燃烧室内旋转。

膨胀气体使转子旋转，产生动力并排出废气。

转子发动机没有活塞和气门等往复部件。

转子发动机产生马力大、无振动，但其燃油消耗比往复式发动机要高。

汽油机和柴油机汽油机以汽油作为燃料。

采用火花塞点燃缸内的可燃混合气，产生动力使汽车行驶，如图1-3a所示。

汽油机也称为火花点燃式发动机。

该发动机的特点是转速高，运行平顺，结构简单，重量轻，成本低。

几乎所有轿车都采用汽油机。

柴油机以柴油作为燃料。

该发动机的工作原理足通过压缩缸内的空气使其升温，冉使喷油嘴喷入的柴油燃烧，产生动力驱动汽车(见图1-3b)，所以也称为压燃式发动机。

柴油机要比汽油机的动力更强劲，燃油经济性更好。

常见于所有的大型货车、客车和部分轿车上。

直列发动机，V型发动机，水平对置式发动机，W型发动机通过气缸数最和气缸排列方式可以识别发动机结构。

当今所有的紧凑型轿车都配有4缸发动机，一些中型级轿车配有6缸发动机，大型轿车配有8缸或12缸发动机。

在多气缸发动机上，气缸通常以四种排列方式中的一种排列，有：直列式、V型、水平对置式和W型。

直列式发动机中的气缸按直线排列，采用一个气缸蓝。

几乎所有4缸发动机都采用该种排列（兄阁1-4)。

第7单元课文B 三元催化转化器现代催化转化器采用了一个三元催化剂块状陶瓷载体，此催化剂载体上涂有铂、钯和铑催化剂金属。

这种载体成蜂窝状，内有数百个废气通道。

这些通道形成了极大的接触表面。

当催化剂处于高温状态时，一般为475～575℉（246～301℃），这些金属元素就会加速催化转化器内的化学反应。

催化剂开始起作用的温度叫做催化转化器的起燃点。

起燃点就是催化转化器转化效率超过50%的温度。

在催化剂达到起燃点后，催化转化器的最大化学转化效率就能达到最大值。

催化转化器安装位置离排气歧管出口越近，达到起燃点需要的时间就越短。

三元催化转化器所引起的化学反应，将碳氢化合物（HC）和氧（O2）转变成二氧化碳（CO2）和水蒸汽（H2O），将将一氧化碳（CO）和氧（O2）转变成二氧化碳（CO2），将氮氧化合物（NO X）和氢（H2）转变成氮（N2）和水蒸汽（H2O）。

这三种有害气体被转变成对环境无害气体的百分数叫做催化转化器的转化效率。

当空燃比保持在14.7:1的理想空燃比时，三元催化剂转换器的效率最高。

三元催化转化器内含有两个单独的陶瓷载体块（图7-5）。

第一个载体内含有还原剂，即使NO X还原的铂和钯。

当NO X（NO和NO2）经过第一块载体时，氮原子与氧原子分离，这个氮原子与另一个吸附在载体上的氮原子结合，而形成氮分子（N2）。

氧化催化剂是含有铂和钯的第二个载体。

氧化催化剂能燃烧（氧化）碳氢化合物（HC）和一氧化碳（CO），并将它们变为二氧化碳（CO2）和水蒸汽（H2O）。

催化转化器中还含有二氧化铈。

在稀薄混合气运行期间以及在还原过程中产生氧的时候，二氧化铈能够存储氧。

然后在浓混合气运行期间再释放出氧，因而维持了催化转化器内的化学平衡。

这个过程能使还原和氧化同时发生。

三元催化转化器在空燃比保持在14.7:1的理想配比状态时效率最高。

如果空燃比比理想配比稀，NO X的转化效率就会下降。

在混合气为稀空燃比即氧含量高的时候，而碳氢化合物含量低的时候，催化转化器仍将转换碳氢化合物，剩余的氧将被存储在催化转化器内。
