When I graduate from the college I shall become a technician. All specialists in automobile industry dealing with manufacturing automobiles (cars or trucks) must know that the production of the automobile comprises the following phases: 1. designing; 2. working out the technology of manufacturing processes; 3. laboratory tests; 4. road tests; 5. mass manufacturing (production). Why is it necessary to know all these facts? It is important to know them, as before the automobile is put into mass production it should be properly designed and the car must meet up-to-date requirements. What are these requirements? The automobile must have high efficiency, long service life, driving safety, ease of handling and maintenance, pleasant appearance. Also it must be comfortable and ecological. In order to obtain these qualities the specialists should develop up-to-date methods of designing cars using new types of resistant to corrosion light materials. Also it is important to know computer sciences because computers offer quick and optimal solutions of the problems. Besides they are used for better operation of mechanisms in cars. Before the car is put into mass production the units of the car are subjected to tests in the Works laboratory and then the car undergoes a rigid quality control in road tests. Why are these tests required? What qualities are required of the automobile? They are needed because the modern automobile must be rapid in acceleration, have smooth acting clutch, silent gearbox, dependable braking and steering systems, dependable ignition system, low fuel consumption and be stable on the road.

UNIT 2 Components of the Automobile Словарь урока
Упражнение 1 Прочтите и переведите интернациональные слова. Automobile, chassis, electric, system, control, differential, ventilator, cylinder.
Прочтите и переведите текст, а затем выполните следующие за ним упражнения. Components of the Automobile The automobile is made up of three basic parts: the power plant, or the engine, the chassis and the body. The engine is the source of power that makes the wheels rotate and the car move. It includes fuel, cooling, lubricating and electric systems. Most automobile engines have six or eight cylinders The chassis includes a power train (power transmission), a running gear, steering and braking systems as well. The power train carries the power from the engine to the car wheels. The power transmission, in turn, contains the clutch, gearbox, propeller or cardan shaft, final drive, differential, rear axle and axle shafts. The running gear consists of a frame with axles, wheels and springs. The body has a hood, fenders and accessories: the heater, stereo tape recorder, windshield wipers, conditioner, speedometer and so on. UNIT 4 Chassis

Упражнение 1. Переведите слова, обращая внимание на суффиксы. Move - movement, construct - construction - constructional, arrange - arrangement, history - historical - historically, wide - widely, vary - various, simple - simply, body - bodily. Gearbox The gearbox is placed between the clutch and the propeller shaft. The principal function of the gearbox is to vary the speed of the car movement to meet the road conditions. The gearbox provides four forward speeds and one reverse, as follows: 1. First or low gear; 2. Second gear; 3. Third gear; 4. Fourth or top gear; 5. Reverse gear. There are many constructional arrangements of gearboxes, which can be classified as follows: 1. Sliding-mesh type; 2. Constant-mesh type; 3. Epicyclic (planetary) type. The sliding-mesh type is the simplest one and is the oldest historically. The constant-mesh type is the most widely used type. They are termed "ordinary" gearing, the characteristic feature of which is that the axes of the various gears are fixed axes. The gears simply rotate about their own axes. The characteristic feature of epicyclic (planetary) gearing is that one gear rotates about its own axis and also rotates bodily about some other axis. To secure the several speeds of the car the clutch shaft is mounted in direct line with the gearbox shaft. The gearbox shaft carries on it the sliding gears which are used for shifting to secure the forward speeds and the reverse drive. Послетекстовые упражнения The exercises to be done after reading the text Упражнение 2. Подберите из правой колонки соответствующие окончания предложений из левой колонки.

UNIT 8 Brakes Словарь урока
Brakes Brakes are used to slow or stop the car where it is necessary. It is one of the most important mechanisms of the car as upon its proper performance the safety of passengers depends. Car brakes can be divided into two types, namely: drum brakes and disc brakes. The drum type may be either a band brake or a shoe brake. Depending on their functions, the automobile has foot brakes and hand brakes (parking brakes). According to their mode of operation, the brakes are classified as: mechanical brakes, hydraulic brakes, airbrakes, electric brakes. Brakes are controlled by the brake pedal. Most braking systems in use today are hydraulic. This system consists of a master cylinder mounted on the car frame and wheel cylinders. When the driver pushes down on the brake pedal, it forces the piston to move in the master cylinder and brake fluid is delivered from it to the wheel cylinders. The piston movement causes brake shoes to move and the brakes are applied (the brake shoes are pressed against the brake drums). The air brake uses compressed air to apply the braking force to the brake shoes. Electric brakes use electromagnets to provide the braking effort against the brake shoes. Formerly brakes were applied only to the two rear wheels, but now all cars are equipped with all-wheels brakes. Today many improvements are being made in brakes. Troubles in Braking System The basic troubles of the braking system are as follows: 1. poor braking action; 2. sticking brake shoes which would not return to the initial position after a brake pedal is released; 3. non-uniform braking of the left and the right wheels on a common axle; 4. leakage of brake fluid and air leakage in the hydraulic brake; 5. poor air tightness of the pneumatic brake control. What to do: 1. Check the action of the foot and hand brakes and leak proofness of the brake hoses connections, components of the hydraulic and pneumatic controls of the brakes, as well as of the vacuum-power system. 2. Inspect the friction linings, wheel-brake springs, master and wheel cylinders of the hydraulic brake, and the air compressor of the pneumatic brake using a test manometer to check it. UNIT 9 Steering system
Упражнение 1. Прочтите слова и сопоставьте их с русскими значениями. column, spindle, system, hydraulic, pump, reservoir, popular, type, effective, effectiveness, effectively, energy, function, to deform, deformation. Упражнение 2. Переведите слова, обращая внимание на суффиксы и префиксы. Rotate — rotation, apply — application, move — movement, develop - development, drive — driver, form — reform — deform — deformation, guide — guidance. Steering System To guide the car, it is necessary to have some means of turning the front wheels so that the car can be pointed in the direction the driver wants to go. The steering wheel in front of the driver is linked by gears and levers to the front wheels for this purpose. The front wheels are on pivots so they can be swung to the left or right. They are attached by steering knuckle arms to the rods. The tie-rods are, in turn, attached to the pitman arm. When the steering wheel is turned, gearing in the steering gear assembly causes the pitman arm to turn to the left or right. This movement is carried by the tie-rods to the steering knucle arms, and wheels, causing them to turn to the left or right. The steering system incorporates: the steering wheel and column, steering gear, pitman arm, steering knuckle arm, front axle, steering knuckle pivot, tie-rods. There are several different manual steering gears in current use, such as the rack and pinion type and the recirculating ball type. The rack and pinion steering gear is widely used. Another manual steering gear which is popular in imported cars is the worm and sector type. The steering wheel and column are the source of injury to the driver, air bags and other devices being developed now to safe the life of a driver. Energy-absorbing columns must stop the steering wheel and column from being pushed to the rear as the front of the car is crushed in an impact. Energy-absorbing columns must also provide the driver with a tolerable impact as he moves forward and strikes the wheel with his chest. Рис. 4. Steering System: 1. steering wheel - рулевое колесо 2. steering column, steering mast — рулевая колонка 3. steering gear - рулевой механизм 4. steering arm, steering lever, (steering) pitman arm — рулевая сошка 5. steering knuckle - поворотная цапфа, поворотный кулак 6. steering knuckle lever, steering knuckle arm - рычаг поворотного кулака 7. single tie-rod - неразрезная поперечная рулевая тяга 8. steering knuckle lever, steering knuckle arm—рычаг поворотного кулака 9. drag link, steering gear connecting rod, steering drag rod—продольная рулевая тяга
Послетекстовые упражнения The exercises to be done after reading the text Упражнение 3. Найдите в тексте ответы на вопросы. 1. What mechanism is necessary to guide the car? 2. How is the steering wheel connected to the front wheels? 3. Why can the front wheels be swung to the left or to the right? 4. What does the manual steering system incorporate? 5. What types of manual steering gears in use do you know? Упражнение 4. Переведите на русский язык, обращая особое внимание на герундий. 1. То guide the car it is necessary to have some means of turning the front wheels. 2. The steering wheel in front of the driver is linked by gears and levers to the front wheels for turning the car in the direction the driver wants to go. 3. Without using the steering system the car moves only in the direct position. 4. Manufacturers can use rack and pinion type steering gear without choosing another type because "rack and pinion" type steering is very dependable. 5. Energy-absorbing columns must stop the steering wheel from being pushed to the rear when the front of the car is damaged in an impact. Упражнение 5. Переведите текст, пользуясь словарем.
