下面是店铺带来的汽车专业英语文章,欢迎阅读!汽车专业英语文章1 The diameter of the cylinder is called the engine bore.Displacement and compression ratio are two frequently used engine specification.Displacement indicates engine size.and compression ratio compares the total cylinder volume to compression chamber volumeThe term"stoke"is used to describe the movement of the piston within the cylinder.The operating cycle may require either two or four stroke to complete. Most automobile engines operate on the four stroke cycleThis type of engine is also know as Otto cycle,after the name of its inventor, Nikolaus Otto,who first applied the principle in 1876.In the 4-stroke engine, four strokes of the piston in the cylinder are required to complete one full operating cycle. Each stroke is named after the action.It performs intake, compression,power, and exhaust in that order, shown in Fig.1-21.Intake strokeThe piston moves downward to the bottom dead center,a vacuum is created in the cylinder.The intake valve opens and air-fuel mixture comes into cylinder .To obtain the maximum filling of the cylinder the intake valve opens about 10' before t.d.c.giving 20'overlap. The inlet valve remains open until some 50'after b.d.c.to take advantage of mixture.pression strokeThe air-fuel mixture is compressed within the combustion chamber.While the pressure rise to about 1MP, depending onvarious factors including the compression ratio, throttle opening and engine speed.The spark plug is fired ignite the air-fule mixture prior to the piston being at the t.d.c..Note that both valves are closed.3.Power strokeThe air-fuel mixture expands, which creates the power to force the piston downward.The exhaust valve opens near the bottom of the stroke.4.Exhaust strokeAs the piston starts to move upward, the exhaust valve is opened.The piston moving up force the exhaust gases out of the cylinder.The intake valve usually opens just before the exhaust stroke.This 4-stroke cycle is continuously repeated in every as long as the engine remains running.汽缸体的直径成为缸径。

关于汽车英语作文(精选22篇)汽车英语作文 1Many years ago, I saw an interesting movie. It pictured thefuture life that people could fly in the sky by cars. Of course, I don’t think it will happen in the coming time. The change in cars is about the energy. It is said that the cars will use both electricity and gasoline, which can reduce pollution. I think it is a great change for cars. More and more people have cars now and the gas they release brings heavy pollution to the air, which damages our health. The cars can use electricity in the long trip. When it runs out of it, then gasoline can be a substitute.许多年前,我看了一部有趣的电影。
电影描绘的是未来的生活,那时候的人们可以坐汽车在天空中飞翔。
当然,我不认为这样的情况会在未来发生,因为汽车的变化主要在能源方面。
据说汽车将使用电油结合,这样就可以减少污染。
我认为这对汽车来说是一个巨大的变化。
现在越来越多的'人拥有汽车,这些车释放的尾气给空气带来了严重的污染,这损害了我们的健康。
汽车可以在长途旅行中先用电,电耗尽时,汽油就可以替换使用。
汽车英语作文 2With the development of modern industry,more and more families are able to have their own cars.But,seeing the problems like air pollution and the reduction of resources,some people appeal for the reduction of private cars.Still,I think there is every reason for the even faster development of the car industry.Thanks to the development of the car industry, we do not have to cram in the buses, but can enjoy in our free travel.With our own cars, we can go to more places in a leisure way. Transportation becomes comfortable and easy. But there are those who worry that too many cars may cause more traffic problems, serious:air pollution andthe exhaustion ofresources, While these problems may be true, they can be solved and some are being solved. For example, we can invent cars that can save fuel or use other types of energy so that cars can still be used even though resources run short. To reduce pollution, people have manufactured many cars without pollution. We can relieve the traffic pressure by building more and more roads or-adopt computer-monitored automated highways.For all the contemporary problems cars bring, no one can deny the convenience cars bring us and ignore the effort that we make to solve these problems. Therefore,the development of the car industry is necessary, and it should develop as quickly as possible.随着现代工业的发展,越来越多的家庭能够拥有自己的轿车。
Engine Fuel SystemThe fuel system has the job of supplying a combustible mixture of air and fuel to the engine. The fuel system must vary the proportions of air and fuel to suit different operating conditions. When the engine is cold, for example, then the mixture must be rich ( have a high proportion of fuel ). The reason for this is that the fuel does not vaporize rapidly at low temperatures. Therefore, extra fuel must be added to the mixture so that there will be enough vaporized fuel to form a combustible mixture.The fuel system consists of the fuel tank, fuel pump, fuel filter, carburetor, intake manifold, and fuel lines, or tubes, connecting the tank, pump, and carburetor. Some gasoline engines use a fuel-injection system; in this system, a fuel-injection pump replaces the carburetor.The fuel tank, in which gasoline is stored, is normally located at the rear of the vehicle.(1) It is made of sheet metal and is attached to the frame.A fuel pump delivers fuel from the tank to the carburetor. There are two general types of fuel pump, mechanical and electric.The fuel system has filters and screens to prevent dire in the fuel from entering the fuel pump or carburetor. Dirt could, of course, prevent normal operation of these units and cause poor engine performance.(2)The carburetor is essentially. a mixing device which mixes liquid gasoline with air. In this process, it throws a fine spray of gasoline into air passing through the carburetor on its way to the engine. (3) The gasoline vaporizes and mixes with the air to form a highly combustion mixture. This mixture then enters the engine combustion chambers, where it is ignited. It burns, causing the engine to produce power. (4) The mixture must be of varying degrees of richness to suit engine operating conditions. It must be rich (have a higher percentage of fuel ) for starting. Acceleration, and high-speed operation. And it should lean out (become less rich ) for operation at intermediate speed with a warm engine. The carburetor has several different circuits, or passages, through which fuel and air-fuel mixture flow under different operating conditions to produce the varying richness of the air-fuel mixture. (5)TireTires have two functions. First, they interpose a cushion between the road and the car wheels to absorb shocks resulting from irregularities in the road. The tires flex, or give, as bumps are encountered, thus reducing the shock effect to the passengers in the car. (1) Second, the tires provide frictional contact between the wheels and the road so that good traction is secured. This permits the transmitting of power through the tires to the road for rapid accelerating, combats the tendency of the car to skid on turns, and allows quick stops when the brakes are applied. (2)Tires are of two basic types, solid and pneumatic (air-filled). Solid tires have very limited usage, being confined largely to specialized industrial applications. (3) Pneumatic tires are of two types, those using an inner tube and the tubeless type. The amount of air pressure used depends on the type of tire and operation. (4) Passenger-car tires are inflated to about 275 to 413 kPa. Air is introduced into the tire ( or inner tube ) through a valve that opens when the chuck on the air hose if applied. On the tire with an inner tube, the valve is mounted on the tube. On the tubeless tire, the valve is mounted on the wheel rim.Suspension SystemThere are two basic suspension systems in use today. One is the solid axle, leaf spring type; the other is the independent suspension using long and short swinging arms. There are various adaptations of these systems, but all use the same basic principle.The solid axle suspension uses a solid steel dead axle (does not turn with wheels ) with a leaf spring at each side. The wheels swivel on each end via a pivot arrangement between the axle and the wheel spindle. (1)With independent suspension, each wheel is free to move up and down with minimum (least attainable ) effect on the other wheel. There is also far less twisting motion imposed on the frame.Rear SuspensionThe leaf spring mounted transversally does require additional bracing; control arms and strut rods are therefore used. (3) With coil springs, the rear-suspension system requires some method of holding the axle housing in place.The coil springs are assembled between spring seats in the car frame and pads on the axle housing. Two control arms, or links, are used. They are attached between the rear-axle housing and the car frame and permit upward or downward movement of the axle housing with respect to the car frame. They prevent side movement or forward and backward movement.Front SuspensionThe suspension of the front wheels is more complicated than the suspension of the rear wheels. Not only must the front wheels move up and down with respect to the car frame ( for spring action ), but also the must be able to swing at various angles to the car frame for steering. (4) In order to permit the front wheels to swing to on side or the other for steering, each wheel is supported on a spindle which is part of a steering knuckle. The steering knuckle is then supported through ball joints, by upper and lower control arms which are attached to the car frame. (5) Independent Front SuspensionPractically all passenger cars now use the independent type of front suspension system in which each front wheel is independently supported by a coil, torsion-bar, or leaf spring. (6) The coil-spring arrangement is the most common. There are three types of coil-spring front suspension. In one, the coil spring is located between the upper and lower control arms, and the lower control arm has one point of attachment to the car frame. In the second type, the coil spring is located between the upper and lower control arms, and the lower control arm has two points of attachment to the car frame. In the third type, the coil spring is between the upper control arm and spring tower or housing that is part of the front-end sheet-metal work.。

Photo courtesy Honda Motor Co., Ltd.Double-wishbone suspension on Honda Accord 2005 Coupe.When people think of automobile performance, they normally think of horsepower, torque and zero-to-60 acceleration. But all of the power generated by a piston engine is useless if the driver can't control the car. That's why automobile engineers turned their attention tothe suspension system almost as soon as they had mastered the four-stroke internal combustion engine.The job of a car suspension is to maximize the friction between the tires and the road surface, to provide steering stability with good handling and to ensure the comfort of the passengers. In this article, we'll explore how car suspensions work, how they've evolved over the years and where the design of suspensions is headed in the future.If a road were perfectly flat, with no irregularities, suspensions wouldn't be necessary. But roads are far from flat. Even freshly paved highways have subtle imperfections that can interact with the wheels of a car. It's these imperfections that apply forces to the wheels. According to Newton's laws of motion, all forces have both magnitude and direction. A bump in the road causes the wheel to move up and down perpendicular to the road surface. The magnitude, of course, depends on whether the wheel is striking a giant bump or atiny speck. Either way, the car wheel experiences a vertical acceleration as it passes over an imperfection.Without an intervening structure, all of wheel's vertical energy is transferred to the frame, which moves in the same direction. In such a situation, the wheels can lose contact with the road completely. Then, under the downward force of gravity, the wheels can slam back into the road surface. What you need is a system that will absorb the energy of the vertically accelerated wheel, allowing the frame and body to ride undisturbed while the wheels follow bumps in the road.照片由本田汽车有限公司,双横臂悬架在本田雅阁2005跑车。

When an irregular signal is initiallymonitored, the PCM decides that a malfunction has occurred and records the occurrence thathas diagnostic trouble code. There are 26 diagnostic items. The diagnostic results can be readwith a scan tool. Diagnostic trouble codes are kept in memory by direct battery feed. The codesare retained in memory even if the ignition switch is in the " LOCK " ( OFF) position.Diagnostic trouble codes will, however, be erased when a battery terminal or the PCMconnector is disconnected. In addition, the diagnostic trouble code can also be erased by scantool ( .Note: If a sensor is disconnected when the ignition switch is in the " ON" position , adiagnostic trouble code is stored in memory. In this case, erase the DTC using scan tool(MUT-III).(3) How to connect the scan tool ( shown in Fig. 2-5-1 )Note: To prevent damage to scan tool, always turn the ignition switch to theLOCK" ( OFF) position before connecting or disconnecting scan tool.OEnsure that the ignition switch is in the " LOCK" ( OFF) position.Start up the personal computer.Connect special tool to the personal computer.Connect special tool to the data link connector.Turn the power switch of special tool to the " ON" position.start the MUT-III system on the personal computer.96 eFig. 2 -S -l 'la ( )I —data link ) 3—personal( 4) HOW to read and erase trouble codesu:onnect scan tool to the data link connector.OTurn the ignition switch to the " ON" position.

It has more advantages than R-12. It does not deplete the ozone Which helps to protect us from the ultraviolet from the sun, and its temperature is muchhigher than that of R-12.The cooling process of the air conditioning system is shown in Fig. 3-2-2. The compressor sucks the refrigerant IOW temperature and low pressure) from an evaporator and changesit into high temperature and high pressure conditions. TTten refrigerant is forced to pass the condenser, in which the heat is dissipated to the air by the electric fan. fie temperature of the refrigerant drops down and its gas condenses to liquid state. When the refrigerant passes the receiver , it is dried, and the fine water drops are left. When the refrigerant passes the expansion valve in the cooling unit, its temperature and pressure corne down, Under low pressure, the refrigerant and the evaporator sucks the heat from the hot air of thecar's interior, and makes it cool, and then sends it back into the car ' s interior. Thus, the refrigerant is cilvulated continuously in air conditioning lines. The driver feels much more comfortable even in hot weather While driving.temperature and the speed Of the air which enters the car are by using theblower speed control switch and mode control switch. This is also onc of the main tasks of the air conditioning system. When AUTO switch is on, the desired temperature is set using the TEMP switch. According to the input signals from sensors and the temperature setting, the air conditioner control ECU determines the air flow volume and outputs signals to the power transistor. When it recæives signals from the ECU, the power transistor increases or reduces the blower motor speed to control the air flow volume.In order to protect the air conditioning system, the degree of cooling is controlled by A/C amplifier. Several sensors such as engine speed sen#'r, engine coolant temperature sensor, evaporator temperature sensor, room temperature sensor, and ambient temperature sensor, etc. , input signals to the A/C amplifier. When the speed of engine or the temperature of engine coolant is low to some degree, the A/C amplifier receives signals from sensors and outputs signals to the compressor magnetic clutch to stop the compressor working.'Ille pressure in the air conditioning piping has great influence on the parts In the piping.Too high or too low prssure is harmful to them. There are several switches to control the system pressure such as high pressure switches and low pressure switches. When the pressure in piping is too high or too low, these switches send signals to A/C amplifier which can control and regulate the degree of cooling to protect the system.Fig. 3-2-2 of Air Condi'ion( side ( ) side (air ( ) ; ( ;air ( (Refrigerant for automobile air conditioners is believed dangerous when it releases. In high temperature or exposed to naked name, the refrigerant will produce a poisonous gas which can suffocate you. nerefore , it is necessary to prevent release of refrigerant to the atmosphere when servicing the air conditioner and to follow the correct service prcw:ess and notices about it.1. Handling precautions for refrigerant( I ) Do not handle refrigerant in an enclosed area or near an open flame.(2) Always 'Mear eye protection.(3) Be careful that liquid refrigerant does not get in your eyes or on your skin.If liquid refrigerant gets in your eyes or on your skin :0) Wash the area with lots Of cool water.Caution: DO not rub your eyes or skin.Apply clean to the skin.Co immediately to a or hospital for professional treatment.Caution : DO not attempt to treat yourself.2. Handling precautions for refrigerant container( ) Never heat container or expose it to naked flame.(2) Be careful not to drop container and not to apply physical shocks to it.3. Handling precautions for gas-cylinder type gas leak tester(l ) Before using tester make sure that there are no flammable substances nearby.(2) Be careful not to inhale poisonous gas.If refrigerant gas comes in contact with flame , a poisonous gas Will be produced.During leak tests, do not inhale any gas.4. Precautions when replacing parts in refrigerant lines( I ) Using a recovery machine, recover refrigerant in system before removing parts. Notice : DO not release refrigerant to the atmosphere.( 2) Insert plug immediately in the disconnected parts to prevent the entry Of moisture and dust.(3) Do not remove plug from new parts until immediately before installation.(4) Do not use burner for bending or lengthening operations on tube.If the lubes are heated with a burner, a layer Of oxidation forms inside the tube,causing the same kind of trouble as an accumulation of dust.(5) Discharge gas in new compressor before installing it.If the gas in new is not discharged first, compressor oil Will spray out withgas when the plug is removed.(6) Tighten connecting parts securely.OSecurely tighten the connecting parts to prevent leaking of refrigerant gas.2Apply a few drops of compressor oil to O-ring for easy tightening and toprevent leaking of refrigerant gas.Wrightcn the nuts using two wrenches to avoid twisting the lube.@ITighten the O-ring fittings or the bolted type fittings to the specified torque.5. Precautions when charging refrigerant( I ) Do not OV:rate compressor without enough refrigerant in refrigerant cycle.If there is not enough refrigerant in the refrigerant cycle, oil lubrication will be insufficient and compressor burnout may occur, so take eare to avoid this.(2) Do not open high pressure valve Of manifold with compressor operating.If the high pressure valve is opened, refrigerant Will flow in the reverse direction and could cause the charging cylinder to So open and close the low pressurevalve only.(3) Be careful not to with refrigerant in system.If refrigerant is overcharged. it will cause trouble such as insufficient cooling, poorfuel economy, engine overheating, etc.。
