（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。
Vehicle manufacturers recommend brake fluid that meets or exceeds SAE (Societyof Automotive Engineers)andDOT (Department of Transportation) specifications.
车辆制造商推荐符合或超过SAE（汽车工程师协会）和DOT（运输部）规格的制动液。
Standard brake fluid (DOT 3) is composed chiefly of equal parts of alcohol and castor oil. This combination of fluids works well under normal conditions but it easily boils and becomes a vapor under heavy-duty applications. It also tends to separate when exposed to low temperatures.
标准制动液（DOT 3）主要由酒精和蓖麻油组成。这种流体组合在正常条件下工作良好，但在重载应用下容易沸腾并成为蒸气。暴露于低温时也容易分离。The increasing requirements of brake fluid led to the development of silicone brake fluid,such as DOT 5. This fluid achieved low water pickup and good corrosion protection and also provides good lubrication qualities and rubber compatibility.
制动液的要求越来越高，导致了DOT 5等硅胶制动液的开发。该液体实现了低吸水率和良好的防腐蚀性能，并且还具有良好的润滑性能和橡胶相容性。
5.Brake valves
5.闸阀
There are typically five types of valves in vehicle braking system to adjust the braking force distribution.
车辆制动系统中通常有五种类型的阀门来调节制动力分布。
(1)Metering valve
（1）计量阀
Most vehicles that have front disc and rear drum brakes are equipped with metering valve. This metering valve controls, or delays the flow of brake fluid to the front brakes. The rear drum brakes take longer to respond than the front disc brakes. The valve ensures that front disc brake do not act before the rear drum brake. The delays is long enough to allow the rear drum brakes time to react. This delay is particularly necessary during light braking and on slick road surfaces.
大多数具有前盘和后鼓式制动器的车辆配备有计量阀。该计量阀控制或延迟制动液流向前制动器。后鼓式制动器比前盘式制动器响应时间更长。阀门确保前盘式制动器在后鼓式制动器之前不起作用。延迟时间足以使后鼓制动时间做出反应。在轻刹车和光滑的路面上，这种延迟特别有必要。

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

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。

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.
