gasoline-powered car in Germany.In the following year,the milestone vehicle was built by Gottlieb Daimler，another German.He perfected the two-cylinder gasoline engine and attached it to the stagecoach,thereby producing the first four-wheeled motor vehicle in the world．2Why did Henry Ford produce automobiles on a moving conveyor line?Answer：In1913,Henry Ford began making automobiles on a moving conveyor line in his factories.He realized that efficient mass production could lower ear prices,making cars affordable for the average person，thus generating a huge market．This was a smashing success.By1916 annual U S auto production reached one million units,a level not reached by any other country until about40years later in England.3What's the function of engine?Answer：The engine acts as the power unit.4What's the function of ignition plug?Answer：The ignition plug supplies the electric spark to ignite the air—fuel mixture in the cylinders.5Why do we need the cooling system on engine?Answer：The cooling system removes excessive heat from the engine.The temperature in engine combustion chambers is about2,000o F(1,094℃).Since steel melts at round2,500o F(1,354℃), this heat must be carried away to prevent engine damage.Air and coolant are used to carry away the heat.6What's the function of storage battery?Answer：The battery stores electricity.It supplies electricity for the ignition,horn,lights,heat and stater.The alternator changes the engine's mechanical energy into electrical energy and recharges the battery.7What do dimensions of all automobile include?Answer：The dimensions of an automobile can make you know the appearance of it．They contain the wheelbase,the track front and rear,the overall length,the overall width,he overall height，overhang front,overhang real,the angle of approach,the angle of departure,interior length, interior width，interior height，the ground clearance，curb weight，gross vehicle weight，number of the doors，seating capacity and trunk or cargo space．8Describe the definition of compression ratio.Answer：Compression ratio are frequently used engine pression ratio compares the total cylinder volume to compression chamber volume.9Please list the name of the four strokes，and explain the working principle of the four strokecycle.Answer：The four strokes refer to intake，compression，combustion(power)and exhaust strokes that occur during two crankshaft rotations per working cycle of the gasoline engine and diesel engine.The cycle begins at top dead center(TDC)，when the piston is farthest away from the axis of the crankshaft On the intake stroke of the piston，the piston descends from the top of the cylinder，reducing the pressure inside the cylinder．A mixture of fuel and air is forced(by atmospheric or greater pressure)into the cylinder through the intake(inlet)port.The intake(inlet) valve(or valves)then close(s)，and the compression stroke compresses the fuel-air mixture.The air-fuel mixture is then ignited near the end of the compression stroke，usually by a spark plug(for a gasoline or Otto cycle engine)or by the heat and pressure of compression(for a Diesel cycle or compression ignition engine)The resulting pressure of burning fuel gas pushes the piston through the power stroke In the exhaust stroke,the piston pushes the products of combustion from the cylinder through an exhaust valve or valves.10How many parts does the chassis consist of?Answer：In the case of a vehicle，the chassis includes four parts：transmission system，driving system，steering system and braking system.11Please write down every part function of the chassis.Answer：The function of the transmission is to transmit the power and torque from the engine to the wheels.The driving system carries the power from the transmission to the differential at the real-wheel axles，causing the rear wheels to rotate.The purpose of the steering system is guiding the car where me driver wants it to go.As we know,the brake system is used to slow down and stop a vehicle.12Please give examples of several forms and features of body.Answer：(1)4x4or4WD(“four by four”or“four wheel drive”)Vehicle：A four-wheeled vehicle with a drivetrain that allows all four wheels to receive power from the engine simultaneously The terms are usually(but not exclusively)used in Europe to describe what is referred to in North America as a sport utility vehicle or SUV f see below).(2)Convertible Vehicle:A body style with a flexible textile folding roof or rigid retracting roof of highly variable design detail to allow driving in open or enclosed modes.(3)Crossover(or CUV)Vehicle:A loose marketing term to describe a vehicle that blends features of a SUV with features of a car especially forgoing the body on frame construction of the SUV in favor of the car’s unibody or monocoque construction.(4) MPV:Multi-purpose vehicle a large car or small bus is designed to be used on and off road and easily convertible to facilitate loading of goods from facilitating carrying people.(5)Pickup Truck:A small，medium，or large-sized truck，though smaller in every case than a Semi tractor truck.The passenger cabin is wholly separated from the cargo bed.(6)Roadster:Originally a two-seat open car with minimal weather protection——without top or side glass though possibly with optional hard or soft top and side curtains(i.e.，without roll—up glass windows).In modem usage，the term means simply a two—seat sports calf convertible，a variation of spyder.13Please write the types of car lights and the roles of the lights.Answer：The lighting system in a typical automobile includes the headlights，parking lights，direction signal lights，side marker lights，stoplights，backup lights，tail lights and the interior lights The interior lights include instrument-panel lights，various warning，indicator and courtesy lights which turn on when a car-door is opened.When the light switch is pulled out,the circuit from the battery to the headlights is completed.This switch has two positions,low beam anddriving beam.These are also called passing beam and high beam.The backup lights come on when the driver shifts into reverse.This closes a switch linked to the selector lever which connects the backup lights to the battery.Blinker lights are installed on many cars to provide a means of signaling when a car is smiled on the highway or has pulled off to the side.The blinking is much mom noticeable than a steady light and provides a warning to approaching ears.14Please list the main categories of the sensors used in the engine electronic control system. Answer：The main categories of the sensors used in the engine electronic control system include AFM，CTS，CMPS，CKPS，TPS，O2S，A／F ratio sensor and KS.15How to operate the EFI system?Answer：The EFI system uses various sensors to detect the engine conditions and automobile running conditions.And the engine ECU calculates the optimum fuel injection volume,and causes the injectors to inject the fuel.16Please list the basic types of automatic transmissions.Answer：There are two basic types of automatic transmissions based on whether the vehicle is rear wheel drive or front wheel drive.On a rear wheel drive car,the transmission is usually mounted to the back of the engine.A drive shaft connects the rear of the transmission to the final drive．which is located in the rear axle and is used to send power to the rear wheels.On a front wheel drive car, the transmission is usually combined with the final drive to from what is called a transaxle.17What are the main components that make up an automatic transmission?Answer：The main components that make up an automatic transmission1nclude:(1)Planetary gear sets which are the mechanical system provide the various forward gear ratios as well as reverse.(2)The hydraulic system uses a special transmission fluid sent under pressure by an oil Dump through the vane body to control the clutches and the bands in order to control the planetary gear sets.(3)Seals and gaskets an used to keep the oil where it is supposed to be and prevent it from leaking out．(4)The torque convener acts like a clutch to allow the vehicle to come to a stop in gear while the engine is soil running.(5)The governor and the modulator or throttle cable monitor speed and throttle position in order to determine when to shift.(6)On newer vehicles．shift points are controlled by computer which directs electrical solenoids to shift oil flow to the appropriate component at the right instant.18Please list the four steps of ABS control cycle.Answer：The four steps of ABS control cycle：(1)EBCM monitoring the wheel speed.(2)Isolating the wheel circuit if the wheel is decelerating too fast(pressure maintain).(3)Reducing wheel circuit pressure if the wheel continues to decelerate too fast.(4)Increasing the wheel circuit pressure when wheel acceleration reaches a preset level.19What is the function of ABS?Answer：An anti-lock brake system(ABS)is a computer-controlled brake system that helps prevent wheels lockup during braking.ABS can maintain control of the vehicle to stop vehicle in the shortest possible distance and in as straight a line as possible，the wheels must be prevented from locking.20Please list the functions of the cruise system.Answer：The cruise control system(CCS)allows you to maintain a set speed above40km/h without keeping your foot off the accelerator pedal.21What is ACC?Answer：Adaptive cruise control(ACC)is an automotive feature that allows a vehicle’s cruisecontrol system to adapt the vehicle's speed to the traffic environment.22Why does the automobile require regular attention and preventive maintenance?Answer：Most of the major parts and systems of the chassis body and engine have predictable use. These parts and systems require regular attention and preventive maintenance.Regular,scheduled maintenance can prevent most common problems and as sure that your car take corrective action. Preventive maintenance will reduce the chance of breakdowns and lower your overall costs.23If a Toyota saloon car’s accelerating capability at high vehicle speed was poor，what will you do?Answer：If a Toyota saloon car’s accelerating capability at high vehicle speed was poor，I shall do as follows:(1)Checking the symptom：(for example)There was a Toyota saloon car，its engine type was2JZ —GE Its accelerating capability at high vehicle speed was poor.(2)Reporting undergoing:(for example)According to what the driver said,firstly gave a drive test which confirmed the driver's description that during acceleration,the output power of the engine is insufficient，likely caused by poor fuel supply So we had a fuel pressure test for the still vehicle The pressure at idle speed was25kg／cm2，and35kg／cm2at acceleration.That was normal Then we checked the sparking timing The result was ing the hand—held tester specifically for Toyota to read trouble codes，we found no trouble codes At last we checked the dynamic data steam.The result was within the accepted range At this time．a11of us were confused，but after consulting with other staff，we were still suspicious of the fuel supply So we linked a fuel-pressure gauge to the fuel rail again and drove the car to have a road test During acceleration，we found that the gauge arm dropped a little.After coming back，we disassembled the fuel pump from the fuel tank and found that the screen was seriously clogged At last，we talked with the driver knowing that his car has run for more than200,000km without any services for the fuel tank.(3)Trouble Solving：(for example)Cleaned the screen and changed the fuel filter The vehicle’s acceleration became satisfied.24What can the screwdriver do?Answer：The screwdriver is a device specifically designed to insert and tighten，or to loosen and remove screws The screwdriver is made up of a head or tip,which engages with a screw,a mechanism to apply torque by rotating the tip,and some way to position and support the screwdriver.25For testing the mechanical side of the engine，you will need some more specialized equipment. Please take some examplesAnswer：For testing the mechanical side of the engine,we need some more specialized equipment.A vacuum gauge with several adapters can be used to test manifold vacuum and test vacuum operated circuits.A vacuum pump is handy for testing vacuum operated components such as EGR valves and heating and air conditioning systems.26How to do the effective diagnosis and troubleshooting when the car breakdown?Answer：The secret of effective diagnosis and troubleshooting is to have a logical well-ordered procedure.Following a logical step-by-step procedure will get you to the root cause of a problem quickly and efficiently.27What can the wrench do?Answer：A wrench or spanner is a tool used to provide a mechanical advantage in applying torque to turn bolts,nuts or other items designed to interface with a wrench.At present，we can see thosetools，like box wrench，electronic torque wrench，combination wrench，adjustable wrench，speed handle and ratchet handle.28What can the diagnostic tree do?Answer：The diagnostic tree goes in a logical progression.It will ask a question，usually yes or no，and depending on the answer will branch off in two or more directions.The last box in the tree will have the problem and how to correct it.A more complicated procedure will have branches going into specific tests and then have two or more branches from there depending on test results. 29How to check the engine oil level?Answer：Check the oil gauge.If under the low level,add the proper oil in the engine.Or dim the dim-stick through the hole in the engine,check the dimmed line.If need,add the proper oil.。

Unit Eight课文A汽车营销中国已成为全世界发展最快的汽车市场，近几年的年平均增长率是26%。
中国汽车业的发展经历了三个阶段。
第一阶段从1953 年到1983年，特点是产量低、技术落后；第二阶段可称为“现代化”阶段，从1984 年到2000年，特点是学习国外的先进技术；第三阶段是指2001年中国加入“世贸组织”后，汽车行业进入生产、销售的快速发展期。
2002和2003年，中国汽车总产量分别增长了38.8% 和36.7%。
2004年，总产量又增长了14.2%。
2005年，中国车市从2004年的萧条状态转向繁荣。
轿车是产量增长的主要力量，而商用车的生产和销售量均有所下降。
2005年中国汽车生产、销售量(单位：百万辆)资料来源: 中国汽车制造业协会2005年，中国汽车产量稳步增长，年生产汽车达到570.8万辆，销售汽车575.8万辆、进口汽车约16万辆，当年汽车销售总量接近591.8万辆。
中国第一次超过日本成为世界第二大汽车生产国，超过德国成为世界第三大汽车消费国，销量仅次于美国和日本。
到2005年，中国无疑已成为世界性的汽车生产和消费市场。
巨大的市场为汽车业发展提供了难得的机会。
假如每年每100个中国人购买一辆汽车，汽车销售量将达到1300万辆，是2005年汽车产量的两倍多。
据预测，更多的中国人将购买家庭汽车。
因此，中国现有的汽车保有量仍然很低，未来几年，市场潜力巨大。
经济的健康发展、人口从农村向需要使用汽车的大城市流动，使生产商不断增加汽车产量。
车价不断降低、新款廉价车型的相继问世，使更多的人买得起汽车。
汽车业的快速发展促进了汽车的生产和销售，但也受到交通基础设施、石油供应和排放标准的限制。
1．交通基础设施到2005年，中国公路总里程数名列世界第二位，但每辆车所拥有的公路里数仅是美国的1/3，日本的1/5，德国的1/6。
尽管投资不少，连接农村和城市的公路依然匮乏。
交通管理也是一个需要改进的领域。
