1.1 The Development of Electric Vehicles
The early electric vehicles, such as the 1902 Wood's Phaeton (Figure 1.1), were little more than electrified horseless carriages. The Phaeton had a range of 18 miles, a top speed of 14 mph and cost $2,000.

New energy vehiclesNew energy vehicles is a new automotive product type, because the development time is not long, the technology is still not mature, so has not yet formed a widely accepted concept, but it certainly is new energy automobile is compared to the traditional fuel vehicles, the new energy vehicles, according to the definition of the scope of the concept size, there are two types of narrow and broad statement.Generalized: used in gasoline and diesel oil as power source of the car.Special: a non conventional vehicle fuel as the advanced technology of powercontrol and drive, the formation of technology has advanced principle, new technology, new structure of automobile.New energy vehicles, including fuel cell cars, hybrid cars, hydrogen powered cars and solar car etc..Hybrid electric vehicle is a vehicle equipped with more than two source:battery, fuel cell, solar cell,Turbine locomotive.The current hybrid vehicles generally refers to the diesel generator, plus battery cars.Advantages:Vehicle starting and stopping, driven only by the battery, do not reach a certain speed,The engine will not work, therefore, can make the engine has been maintained in the best condition, good dynamic performance, very low emissions, and the source and power are the engine, gas can only. Its principle is simply the motor and engine the reasonable arrangement of power output machine.Disadvantages:There are two sets of power,Management control system plus two sets of dynamic,Complex structure,Difficult,The price is high and long distance speed is not fuel-efficient.Pure electric vehicle is composed entirely of rechargeable battery (such as lead-acid batteries, nickel cadmium batteries, nickel hydrogen batteries or lithium ion batteries provide power source for car).Pure electric vehicle motor fuel to replace machine, low noise, no pollution,and by the use of electrical energy single, electric control system of hybrid electric vehicle is greatly simplified compared. Reduces the cost, the price also can compensate the battery. Pure electric vehicle is mainly used for the airport, community, courts and other places.Disadvantages: only in certain range, the market is smaller. The main reason is because of various categories, the prevailing prices high, life is short, the size and weight of the large, long charging time, serious shortcomings.Fuel cell vehicles refers to the hydrogen, methanol as the fuel, the current through the chemical reaction, depending on the electric motor driven vehicles. The battery power is through the chemical reaction of hydrogen and oxygen, rather than through the combustion, directly into electrical energy.The chemical reaction process of fuel cell does not produce harmful products,therefore the fuel cell vehicle is a car without pollution, energy conversion efficiency of the fuel cell of high 2 ~ 3 times than the internal combustion engine, so the use of environmental protection and energy, fuel cell vehiclesand is an ideal vehicle.Household car is more and more, oil prices more and more expensive, every car company began to research and development of new energy vehicles.1.IntroductionChery since 2000 we have engaged in the research and development of the new energy vehicles, through more than ten years of independent innovation, the new energy vehicles business experienced three important stages of development; From 2001 to 2005, the company with the national 863 project for the carrier, joint top Chinese universities and research institutes, undertake and completed a number of national 863 electric vehicle research subject, the major projects in just3 years time, complete the ISG moderate hybrid and pure electric vehicles of the rational development model. From 2005 to 2008, approved by ministry of a "by national energy conservation and environmental protection automotive engineering technology research center", based on the basic completion of the new energy vehicles of the industrialization of the research and development, the establishment of a sound energy saving and new energy vehicle development system, the world first-class new energy test center, trial-produce center, in the electric car key components and core technology, the company has formed a set of key parts research, testing, application and industrialization of calibration ability, in the motor, motor drive system, DC/DC, advanced power battery, the battery management system, the vehicle controller, initially forming a batch production ability, have the new energy vehicles, the core technology of the calibration technology and experiment technology. New energy vehicles special vehicle accessories system, including: electric air conditioning, the electric steering (EPS), electric vacuum, electric heating, electronic brake system has been formed series products, with the bulk production ability. The first paragraph A5-BSG hybrid cars in 2008 listed in wuhu, batch, dalian city, as the taxi are greatly welcomed by customers, but also become henan, guangdong, xinjiang, shanxi, fujian, zhejiang and other private user's private cars. Moderate hybrid (ISG) car has entered the small batch production stage, which is DuoGe new energy vehicle demonstration pilot city, as the lease, the first choice of state-owned cars models. Miniature pureelectric vehicles and intermediate pure electric vehicles and miniature electric buses, pure electric taxies, pure electric bus industrialization development also has made a great progress. At the same time, we also pay more attention on high efficiency and energy saving the gasoline engine, the diesel engine technology, flexible fuel automobile technology, strong hybrid technology, fuel cell vehicle technology, comprehensive development, a number of technical are in the leading domestic level. Since 2009, the company launched a new comprehensive energy car large-scale industrialization and application, chery A5ISG, A5BSG, S11EV and S18EV has got a letter issued by the department work products in the country the announcement and saving energy and environmental protection products recommended directory; In January 2009, chery automobile company "energy conservation and environmental protection technology platform construction project" get "country" first prize progress prize in science and technology. In March 2010 the first batch of economical pure electric car delivery customers use and chery new energy vehicle technology Co., LTD. was set up, marked the new energy vehicle company opened a new chapter in the business2.Main discussion1. The advantages of new energy vehicles (strength) analysisThe state information center forecast, China's passenger car market growth situation will continue for at least a further 15 years, annual growth needs roughly equivalent to GDP growth in the 1.5 times or so. In 2009 a car into the family (middle-income families buy have ability). From the qualitative Angle, car market at least will also have 20 years of fast growth. If domestic GDP2020 years than in 2000, around 2020 words to quadruple our country will more than the United States, automobile demand will reach 20 million cars, as the world's largest car market.Since 1988, in fujian province, and become the largest of the special economic zone, the provincial capital of hainan province since the haikou city become haikou city won the top ten cities, and national environmental protection model city, national sanitary city, China excellent tourist city, national garden city, national historical and cultural city, a national civilization city advanced city, the work the comprehensive improvement of the urban environment, "China excellent city living environment prize" and so on the city reputation. Hainan consistent development of the island, environmental protection island is travel health island, new energy, cars are the city's another environmental and health. From the economic development prospects and haikou city car market development scale, in the city to see public transport, taxi, business, environmental sanitation and postal and other public service and other fields, new energy vehicles have a large market space.2.New energy vehicles disadvantages (weakness) analysis(1) the traffic congestion, chaos. Nearly five years motor vehicles and drivers haikou number to sustained growth, road traffic management brought unprecedented pressure. According to information, haikou city road 859 existing with a total length of 1797 km, motor vehicle ownership of 250000 vehicles per day, and are at a 200 rate, of which the amount of private cars is as high as 26%, to the current haikou is obviously can't meet the transportation network of motor vehicle driving demand. Second, the city center area road reconstruction speed slow, to the original road reconstruction is not form system engineering, special is ages ago, DuanTouLu neck road has not been effective reform. Constrain the other major trunk and disperse traffic volume ability. Again, there are pure state road traffic and the lagging problems, such as haikou existing parking lot for cannot accommodate next overmuch vehicles, lead to the driver in some sections on both sides of the parking. This makes originally not wide road become more narrow. There is traffic development, citizens behind haikou travel a single pattern, motorcycles, cars, etc, make travel has become the public preferred way material utilization rate reduced. If the road is sabafish intermediary haikou motorcycles and elegant demeanour car most serious place one of the flood. In the waiting by the shop, packed with motorcycles and elegant demeanour car. They ZhanDao rob guest, obstruct the other vehicles, normal traffic caused easily traffic jam. Haikou traffic police is insufficient, the control points, blind area, people's traffic, too weak, the bus lines concept overlap serious, site layout is not reasonable. Some sections of the serious traffic jam, especially holidays or rush, traffic is chaos.(2) for less than for parking. Data shows, at present, haikou has more than 160000vehicles auto possession, and with more than 20000 cars a year speed increases. The current haikou on an average day with more than 60 new car the road, in a day and added between so many parking obviously is not very practical. In the next few years, whether public or parking garage area will be more strained3.Wide range of reading up to dataHybrid cars advantage is: 1, the hybrid power may according to the average need after the power to determine the maximum power of internal combustion engine, right now in oil consumption is low, less pollution the optimal conditions work. Need high power internal combustion engine power shortage, the battery to supplement; Load for a little while and surplus power can power generation to recharge the battery, due to the internal combustion engine, the battery and sustainable work can constantly, so their trip and charging as ordinary cars. 2, for there is a battery, can be very convenient recycling braking, hill and idle when energy. 3, in the noisy city, can shut by internal combustion engines, battery, to achieve "drive alone zero discharge". 4, with internal combustion engines can be very convenient solve energy consumption of the air conditioning, heating, such as pure electric vehicle defrosting problems met. 5, can use the existing gas station come on, don't have to investment. 6, can let the battery to keep in good working condition, not happened, filling put, prolong the service life, and reduce the cost.Faults: long distance high-speed basic can't save fuel4.PresentationThe essay take about chery Hybird car in china.This kind of car is very useful for every family.because of Hybird car can save petrol .so it’s cheaper than other cars. Sometimes,this kind of cars can use electric it can protect environment also can control the climate change. This very accord with China's national conditions. In the future green cars are very popular to use in the world.翻译新能源汽车作为一种新的汽车产品类型,由于发展时间还不长,技术还不成熟,所以尚未形成一个被广泛认可的概念,但是肯定的是新能源汽车的提出是相对于传统燃料汽车而言的,目前关于新能源汽车的概念根据其定义范围的大小,有狭义和广义两种说法。

UNIT 5 FUEL INJECTION SYSTEM燃油喷射系统Fuel injection systems have been used on vehicles for many years. The earliest ones were purely mechanical. As technology advanced, electronic fuel injection systems became more popular. Early mechanical and electronic fuel injection systems did not use feedback controls. As emissions became more of a concern, feedback controls were adapted to both types of fuel injection systems.feedback control 反馈控制As emissions became more of a concern 随着排放越来越受到关注were adapted to 被应用于Both mechanical and electronic fuel injection systems can be found on gasoline engines. Diesel engines are most commonly found with mechanical type systems, although the newest generations of these engines have been using electronic fuel injection(EFI) .gasoline engines 汽油发动机diesel engines 柴油发动机newest generations of 最新的5.1 Basic TheoryEFI uses solenoid valves called injectors to meter fuel delivery. Most vehicles today use 1 injector per cylinder. When the solenoid is energized, fuel sprays out into the valve port. Fuel is delivered to the injector by a high-pressure electric pump at around 40 psi. Fuel delivery is controlled by the injectors which are cycled by the computer. The computer produces a signal to open the injectors for a certain length of time depending on engine conditions relayed by sensors. The longer that the injector is open, the more fuel is injected. As engine load and rpm are increased, the injector open times are increased to match increasing airflow. This computer output signal is called the injector pulse width. The longer the pulse width, the more fuel is injected.solenoid valves 电磁阀injector 喷油嘴,喷油器,喷射器fuel delivery 燃油输送,燃油供给is energized v. 使通电,供能, 激发,加强adj. 通电的,激励的,增能的energized line 带电电路,带电线路valve port 阀口,喷油嘴psi [psai] 每平方英寸….磅=pounds per square inchare cycled by 周期性控制engine conditions relayed by sensors 传感器传送/输送回来的信号体现的发动机工作状况,简单的说,即:传感器信号体现的发动机工作状况injector pulse width 喷油器脉冲宽度5.3 Fuel System5.4 Air Metering and Measurement5.5 Most EFI systems measure the same basic 6 inputRPMAirflow空气流量Manifold Pressure 歧管压力On speed density type systems, this input is essential when combined with the rpm signal to calculate airflow. As the throttle is opened, the manifold pressure increases which will require more fuel.speed density type system “速度-密度”类型的系统,即:采用“速度-密度”方法来测量空气流量的系统Throttle Position 节气门位置This input is a secondary input on most systems. It is required mainly for acceleration enrichment when the throttle is rapidly opened. By looking at the rate of change of throttle blade angle, the computer can determine how quickly the throttle is being opened and can supply the extra fuel required momentarily to alleviate the lean condition. Throttle position is measured by a potentiometer attached to the throttle shaft.acceleration enrichment 加速加浓,即:汽车加速时的混合气加浓looking at the rate of change of throttle blade angle 查看节气门叶片转角的变化速率determine 确定momentarily ['məuməntərili] adv. 即刻,随时地,暂时地,立刻alleviate [ə'li:vieit] v. 减轻,使...缓和,使(痛苦等)易于忍受alleviate burdens 减负lean condition 稀混合气工况←←→→rich condition 浓混合气工况potentiometer [pə,tēnʃi'ɔmitə] 电位计,分压计,电位器,电势计Water TemperatureAir Temperature5.6 Oxygen Sensor 氧传感器This sensor is employed in closed loop systems to modify the basic pulse width after the fact. It is mounted into the exhaust manifold area. By looking at the oxygen content of the exhaust gasses after combustion, the computer can determine if the air/fuel ratio is too rich or too lean for optimum combustion and adjust the next few injections accordingly. This sensor is primarily employed for emission control and to a lesser degree, fuel economy. For the lowest average emissions, the air/fuel ratio must be kept around 14.7 to 1.is employed in 应用于,忙于,从事于closed loop systems 闭环控制系统modify the basic pulse width after the fact 事后调节基本脉冲宽度oxygen content 氧含量combustion 燃烧the next few injections 接下来的/后面的一些喷油(脉宽)emission control 排放控制to a lesser degree 在更轻的程度上,其次Under full throttle conditions, this sensor input is ignored by the computer so that the engine can produce more power. This is called open loop mode and the computer is supplying the injector pulse width from tables based on all of the other sensor inputs. Once throttle opening and rpm are reduced to cruising conditions, most systems will jump back into the closed loop mode where they will stay for a large portion of the time on most street driven applications.full throttle conditions 节气门全开的情况/工况open loop mode 开环控制模式supplying the injector pulse width from tables based on all of the other sensor inputs 根据(除了氧传感器之外的)其它所有的传感器输入信号得到的(喷油)数据表来提供喷油器脉宽cruising conditions 巡航工况street driven applications 街道驾驶应用,意译即:街道行驶情况5.7 Basic OperationAs explained in the Basic Theory section, the computer processes all of the voltage signals from the various sensors to determine the engine operating conditions at the moment and delivers the appropriate pulse width to the injectors. If engine airflow increases by 10%, the pulse width is also increased by about 10% to keep theair/fuel ratio constant. If the rpm is doubled from 2,000 to 4,000 rpm, the numbers of injections are also doubled to double the fuel flow.The computer looks at the changes in sensor inputs every few milliseconds in order to be ready to modify the pulse width if any parameter changes.Section 章节,部分at the moment 此刻,目前,现在at the right moment 适时appropriate [ə'prəuprī:ət] adj. 适当的v. 拨出(款项)(某目的)之用constant ['kɔnstənt] adj. 恒定的, 经常的,不变的,持久的n. 常数,恒量every few milliseconds 每隔几毫秒parameter [pə'ræmītə] n. 参数,参量NEW WORDS1. feedback 反馈2. injector 喷油嘴,注射者,注射器,喷射给水器3. sensor7. alleviate减轻,使...缓和8. momentarily 即刻,立刻, 随时地,暂时地PHRASES AND EXPRESSIONS1. electric pump 电动泵2. pulse width 脉冲宽度3. fuel rail 油轨4. return line 回油路5. fuel pressure regulator燃油压力调节器6. throttle body assembly节气门体总成8. measure off测量出9. hall effect sensor 霍尔效应传感器10. taper off使渐渐减少, 逐渐停止,使渐渐变尖,一头逐渐变细UNIT 6 EXHAUST SYSTEM排放系统The exhaust system carries exhaust gases from the engine’s combustion chamber to the atmo sphere and reduces, or muffles, engine noise.

With a dual exhaust system, a sizable increase in engine horsepower can be obtained because the “breathing” capacity of the engine is improved, leaving less exhaust gases in the engine at the end of each exhaust stroke.

Most of these systems can be placed into one of threedistinct groups: the conventional breaker point type ignition systems (in use since the early 1,900s); the electronic ignition systems (popular since the mid 70s) ; and the distributorless ignition system (introduced in the mid 80s).The automotive ignition system has two basic functions: it must control the spark and timing of the spark plug firing to match varying engine requirements, and it must increase battery voltage to a point where it will overcome the resistance offered by the spark plug gap and fire the plug.be placed into 分成,归结为conventional breaker point type ignition systems 传统的触点式点火系统electronic ignition systems 电子点火系统distributorless ignition system 无分电器点火系统introduced 引入,开始采用spark 火花timing of the spark plug firing 火花塞点火的定时varying 变化的battery voltage 蓄电池电压resistance (火花塞间隙的)阻力spark plug gap 火花塞间隙7.1 Point-Type Ignition System7.2 Electronic Ignition Systems7.3 Distributorless Ignition Systems (DIS)The third type of ignition system is the distributorless ignition. The spark plugs are fired directly from the coils. The spark timing is controlled by an Ignition Control Unit (ICU) and the Engine Control Unit (ECU). The distributorless ignition system may have one coil per cylinder, or one coil for each pair of cylinders.are fired 被点火coils (点火)线圈spark timing 火花定时,即:火花塞点火的时刻Ignition Control Unit (ICU) 点火控制单元cylinder ['sīlində] 汽缸,圆筒,圆柱体,汽缸套Some popular systems use one ignition coil per two cylinders. This type of system is often known as the waste spark distribution method. In this system, each cylinder is paired with the cylinder opposite it in the firing order (usually 1-4, 2-3 on 4-cylinder engines or 1-4, 2-5, 3-6 on V6 engines, Figure 7-4). The ends of each coil secondary leads are attached to spark plugs for the paired opposites. These two plugs are on companion cylinders, cylinders that are at Top Dead Center (TDC) at the same time. But, they are paired opposites, because they are always at opposing ends of the 4-stroke engine cycle. When one is at TDC of the compression stroke, the other is at TDC of the exhaust stroke. The one that is on compression is said to be the event cylinder and one on the exhaust stroke, the waste cylinder. When the coil discharges, both plugs fire at the same time to complete the series circuit.waste 荒芜[废]的, 荒凉的,废弃的, 无用的, 多余的; 排泄的,[喻]贫乏的; 单调的waste spark distribution method 多余的火花分配方法,即:有一气缸是无用的火花点火方法In this system, each cylinder is paired with the cylinder opposite it in the firing order (usually 1-4, 2-3 on4-cylinder engines or 1-4, 2-5, 3-6 on V6 engines, Figure 7-4). 在这种系统中,每一汽缸按照点火顺序与和它相对的/相反的那一汽缸配对使用(这配对使用是指成对同时点火),在四缸发动机中点火顺序通常是1、4缸配对先点火, 2、3缸配对后点火,或者在V型六缸发动机中,通常是1、4缸配对先点火, 其次是2、5缸配对点火, 最后是3、6配对点火,如图7-4coil secondary leads 点火线圈次级导线paired opposite 配对的相反的那一缸companion 成对的Top Dead Center (TDC) 上死点,上止点opposing ends 相反的那一端4-stroke engine cycle 四冲程发动机的循环周期compression stroke 压缩冲程exhaust stroke 排气冲程event cylinder 做功的气缸waste cylinder 不做功的气缸discharge 放电series circuit 串联电路The advantages of no distributor, in theory, are:1.

The drive line or drive train transfers the power of the engine to the wheels. The drive train consists of the parts from the back of the flywheel to the wheels. These parts include the clutch, the transmission, the drive shaft, and the final drive assembly (Figure 8-1).The clutch which includes the flywheel, clutch disc, pressure plate, springs, pressure plate cover and the linkage necessary to operate the clutch is a rotating mechanism between the engine and the transmission (Figure 8-2). It operates through friction which comes from contact between the parts. That is the reason why the clutch is called a friction mechanism. After engagement, the clutch must continue to transmit all the engine torque to the transmission depending on the friction without slippage. The clutch is also used to disengage the engine from the drive train whenever the gears in the transmission are being shifted from one gear ratio to another.drive line or drive train 传动系transmission 变速器,变速箱drive shaft 传动轴final drive assembly 末端传动总成flywheel 飞轮clutch disc 离合器盘,即:离合器从动盘pressure plate 压盘pressure plate cover 压盘盖linkage 操纵杆系friction 摩擦engagement 结合disengage the engine from….将发动机从…..分离gear ratio 齿轮齿数比,齿数比,齿轮比,即:传动比steering gear angle ratio 转向器角传动比gear reduction ratio 齿轮减速比being shifted from one gear ratio to another. 从一个传动比变化到另一传动比,即:发动机从一个档换到另一个档The advantages of a diaphragm type pressure plate assembly are its compactness, lower weight, fewer moving parts, less effort to engage, reduces rotational imbalance by providing a balanced force around the pressure plate and less chances of clutch slippage.diaphragm type pressure plate assembly 膜片式压盘总成compactness 结构紧凑effort ['ēfət] 努力,施力, 努力的成果,效能less effort to engage 结合更省力NEW WORDS1. clutch2. flywheel3. stationary ['steiʃ(ə)nəri] 不动的,稳定的,静止的n. 固定物,驻军4. torsional ['tɔ:ʃənəl] 扭力的,扭转的,扭转的5. crankshaft 曲轴6. stall 停止,停转,失速7. mount8. groove 槽9. lever ['li:və, 'levə] 杠杆,杆,似杠杆之工具,手段v. 撬开,使用杠杆10. pivot ['pivət] 在枢轴上转动, 旋转n. 旋转轴,支点, 枢, 枢轴, 中枢11. gearbox ['giəbɔks] 齿轮箱, 变速箱,减速器,传动箱12. retract 退回,拉回,缩进,收回,取消13. compactnessPHRASES AND EXPRESSIONS1. drive train2. drive shaft3. pressure plate4. clutch disc5. gear ratio6. release bearing 分离轴承7. release fork 分离叉8. master cylinder (液压缸的)主缸9. clutch pedal 离合器踏板10. coupling device 接合装置11. at idle 在怠速时12. couple with 与….接合13. ring gear 齿圈14. pinion gear 小齿轮15. splined hub 花键毂16. cast iron 铸铁17. diaphragm spring 膜片弹簧19. engage with 与….啮合/接合20. centrifugal force 离心力Reading material: Torque Converter液力变矩器,转矩变换器,变矩器The BasicsJust like manual transmission cars, cars with automatic transmissions need a way to let the engine turn while the wheels and gears in the transmission come to a stop.

车辆工程专业英语概述

车辆工程专业英语概述The Principal Components Of Automotive张可可2021210612The Principal Components Of Automotive contains the body, the engine , the chassis , the power train system, the steering system, the suspension system and wheels , the braking system and the electrical and electronic system.1 The bodyAn automobile body is a sheet metal shell with windows, doors, a hood anda trunk deck built into it.It provides a protective covering for the engine, passengers and cargo. It is designed to keep passengers safe and comfortable. The body styling provides an attractive, colorful, modern appearance for the vehicle.2 The engineThe 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 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 torotate a shaft connected to the power train.3 The chassisChassis is the frame on which the engine, body, wheels etc. are built. The chassis is an assembly of those systems that are the major operating parts ofa vehicle. It includes power train which conveys the drive to the wheels, steering which controls the direction of movement,suspension and wheels which absorb the road shocks, and brake which slows down the vehicle.4 The power train systemThe power train transfers turning effort from the engine to the driving wheels. It include a clutch ( manual transmission) or a torque converter (automatic transmission), a transmission drive shaft, final drive and differential gear s and driving axles. Alternatively, a transaxle may be used.A transaxle is a self-contained unit with a transmission, final drive gears and differential located in one casing.The directional motion of vehicle is controlled by a steering system. A basic steering system has 3 main parts: a steering box connected to the steering wheel, the linkage connecting the steering box to the wheel assembly at the front wheels and front suspension parts to let the wheel assemblies pivot. When the driver turns the steering wheel,a shaft from the steering column turns the steering gear. The steering gear movestie-rods that connect to the front wheels. The tie-rods move the front wheels to turn the vehicle right or left.5 The braking system and wheelsThe purpose of the complete suspension system is to isolate the vehicle body from road shocks and vibrations, which will otherwise be transferred to the passengers and load. It must also keep the tires in contact with the road regardless of road surface. A basic suspension system consists of springs, axles, shock absorbers, arms, rods and ball joints.The tire provides a cushion between the vehicle and the road to reduce the transmission of road shocks. It also provides friction to allow the vehicle to perform its normal operations. Modern tires are manufactured from a range of materials. The rubber is mainly synthetic. Two types of tire construction are common: cross-ply and radial. Most passenger cars now use radial tires, and radials are replacing cross-ply tires on 4-wheel drives and heavy vehicles.6 The braking systemDrum 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 brakepads. On lightvehicles, both of these systems are hydraulically operated. The brake pedal operates a master cylinder. Hydraulic lines and hoses connect the master cylinder to brake cylinders at the wheels. Most modern light vehicles have either disc brakes on the front wheels and drum brakes on the rear or disc brakes on a11 4 wheels. Disc brakes require greater forces to operate them. A brake booster assists the driver by increasing the force applied to the master cylinder when the brake is operated.7 The electrical and electronic systemThe charging system provides electrical energy for all of the electrical components on the vehicle. A typical charging system includes: a battery, an alternator, a voltage regulator which is usually integral to the alternator, a charging warning or indicator light and wiring that complete the circuits. The battery provides electrical energy for starting, then once the engine is running the alternator powers all the electrical components of the vehicle. The alternator also charges the battery to replace the energy used to start the engine. The voltage regulator prevents overcharging. The starting system consists of the battery, starter, flywheel ring gear, cables,and the ignition switch. The starter motor is powered by the battery. During starting, the pinion of the starter motor engages withthe flywheel ring gear and the starter motor then operates to crank the engine.Electrical is related to the electricity while electronic related to the semi-conductor or microcomputers. The electrical system provides electricity to the starter, ignition, lights and heater. The electricity level is maintained by a charging circuit.That's all.感谢您的阅读,祝您生活愉快。

Characteristics and Development of Some Kinds of New Energy VehiclesAbstractNow the global automotive industry is facing the challenge of energy and environment,and developing new energy vehicles becomes many global automotive groups’s same plan.But not all of various types of new energy vehicles which have their own advantages and disadvantages can become the most promising future vehicles.I will introduce features and development of Pure Electric Vehicles 、Hybrid Electric Vehicle (HEV)、Fuel Cell Electric Vehicles (FCEV)、Natural Gas Vehicles、Hydrogen Engine Vehicles and DME Vehicles Etc. At last we will know which kind of the new energy vehicles will become mainstream in the future of the car by comparing.Key Word: New Energy Vehicles Future cars HybridHybrid cars is hybrid electric vehicles which use more than one kind of energy provides power to drives the car . Currently hybrid cars is the combination of traditional fossil fuels engin and electric motor. The most prominent advantage of hybrid cars is its fuel economy. The maximum power of the engin can determine by the average power ,so that the engin can work in less pollution and lower fuel consumption condition. That makes hybrid cars save 30%~50% fule compare with traditional cars,and significantly reducing emissions at the same time.Energy recovering from braking become easy too.But the problem of hybrid car is it’s high price and basicly no fuel saving at long distance、high speed driving.At present, China's hybrid vehicle technology development fast, some models have been in the period of practical .Take the Roewe 750 of Shanghai Automotive Group for example ,it has already on sale.In the world wild,Toyota Prius hybrid car first introduced in Japan in 1997,and the other major automobile companies havelaunched their own hybrid products, such as the Honda Insight, GM Saturn VUE, Ford Escape and so on.With technical progress and expansion of production scale,the cost has dropped significantly.Pure electric vehicles is driven by electric motor, which is powered by car-carry battery,and meet the requirements of traffic safety regulations.Pure electric vehicle using a rechargeable battery , and the basic structure is not complicated.Electric generators and car batteries are one of the key components, among which the most critical is battery.Pure electric vehicles is not a new car, the electric car was born more than 100 years. At that time the electric car battery lifespan is short, the mileage is not high also. Then the electric car is relaced by the increasingly technology mature internal combustion engine car. But in the 1970 s, due to the stimulation of oil crisis, all countries in the world began to look for other energy to replace oil. The electric car is back in the line of sight of people. And in recent years besides had the problems of energy, environmental problem has become a social focus on major issues. Againincreased focus on electric cars. Now the difficulty of promote puer electric car comes from the power storage technologies.Currently,energy storage in per unit weight of the battery is not enough for long -term using, the charge mileage is not ideal. On the other hand,The high-performance battery lifespan is short.Resulting in not froming economy scale, cost of pure electric vehicle is too high to commercial operation.Nevertheless, pure electric vehicles are promoted in the U.S., Europe, Japan in small-scale,and mainly use in government vehicle ,city bus Etc. The forerunner of China's electric car company BYD launched E6, and also exported electric bus to Europe .Fuel cell electric vehicle use a fuel cell as electric source to supply electric motor, and the chemical energy of fuel is directly changed into electrical energy by the cell.The energy conversion efficiency of the fuel cell is 2 to 3 times higher than internal combustion engines, and fuel cells do not produce harmful chemical reaction products and make lower noise.In recent years, although the development of fuel cell vehicles technology has made significant progress in the world wild , but there are still some technical challenges, such as the integration of fuel cells,vehicle integration, industrialization and commercialization. It is worth mentioning that we are at the same level with developed countries in the field of fuel cell electric vehicle researching.Hydrogen engine vehicle power by the engin which is transform from the existing automobile internal combustion engine.In addition to the hydrogen engine car has the same advantages of less pollution, lower emissions, but also has other special advantages, such as lower requirements for hydrogen, high combustion performance, engine technology is mature and so on.But now hydrogen engine car facing with problems of preparation and storage of liquid hydrogen .Ability to effectively solve these two problems in short time will determine the prospects for the development of hydrogen engine vehicles.Natural gas vehicles to use natural gas as fuel .According to the chemical composition and morphology of natural gas ,it can be classified as three kinds of it ,like Compressed Natural Gas (CNG), Liquefied Natural Gas (LNG) and Liquefied Petroleum Gas . Because natural gas vehicles using natural gas as fuel, so it has some feature like low pollution, low cost and high security.But natural gas vehicles have lower power performance, not easy to carry compared with normal vehicle. And once put into Large-scale using, we must build the appropriate station and pipeline.It also relates to design urban planning, funding and environmental safety, and many other factors, causing the high cost of using this kind of vehicle.China is rich in natural gas resources, and natural gas vehicle technology developed rapidly in these years . For example, some taxi Changsha use Compressed Natural Gas engin.In addition to the above new energy vehicles, as well as,there is also a kind of vehicle using organic substance, such as alcohol, ether as fuel to power the car.Ethanol fuel is ethanol automotive gasoline, ethanol vehicle technology is relatively mature, thetraditional internal combustion engine can modification to adapt to different ethanol gasoline fuel. The rapid development of ethanol cars happen in United States, Brazil and other countries thanks to the rich ethanol resources, while China is still in its initial stage.DME car use DME as fuel of compression-ignition engine. Generally using in two ways: Firstly, using the dimethyl ether as an ignition-promoting secondly dimethyl ether used as the direct combustion of liquid to get power.Dimethyl ether automobile technology in China has made important progress, such as Shanghai automotive group has successfully developed in dimethyl ether city bus, and began the trial runThanks to internal combustion engine technology is now very mature, hybrid cars is ease of using , sustainability, reliability is better than that of other new energy cars, but its still use gasoline, diesel oil as a source of energy, so the hybrid vehicle can't represent the future type of car. And because the power can be obtained from a variety of one-off energy,do not worry about energy draining, so pure electric vehicle has broad application prospects. At the same time, pure electric vehicles has no pollution, makes lower noise, is high efficiency. These advantages make this type of electric car research and application is becoming a hot spot of the car industry, and our country also take electric vehicles as the main orientation of auto industry strategic transformation. Fuel cell vehicles, with its efficient green cleaning and life advantage to get the attention of many countries to continuously invest devotion, therefore the fuel cell car will also be important form of the cars of the future. For other types of new energy vehicles, because of the limitations of fuel supplying, can't be used in the large scale all over the world. And this kind of alternative fuel in the engine power performance, corrosion, storage and transportation difficulties, such as obvious shortcomings. This kind of new energy vehicles may will be the future regional auto supplement type.Comparing the above list of various types of new energy vehicles, pure electric vehicles will be themainstream of future automobiles, fuel cell vehicles will act as an important component in the future , and a hybrid car is the transition models before exhausting of petrochemical resources, other types of cars are supplement adjust measures to local conditions. Pure electric vehicles is the most promising new energy vehicles, and is strongly supported by the state.Now some electric vehicles is used in the urban public transport, major activities.We look forward to the clean traffic early arrival of the era.References[1]邹政耀,王若平.新能源汽车技术.北京:国防工业书版社,2012[2]石川宪二.新能源汽车技术及未来.康云龙,余开江译.北京:科学出版社,2012[3]冯景毅.基于48V电压平台解读比亚迪绿混技术.汽车之家网,2013[4]黄正桥.陈斌波:电动汽车是未来汽车发展的方向.汽车之家网,2011[5]Sperling, Daniel.Two Billion Cars:Driving Toward :Oxford University Press,2009[6].Ranjan K.
