汽车专业英语期末考试题型说明

Terminal Reviews to English for the Automotive Profession I. Answer the following questions.(20%) Choose 5 of 6, 4 points for each, total in 20 points. 1. What does the drive train consist of? The drive train consists of clutch, transmission, driveshafts, differentials, and the final drive (drive wheels, continuous track like with tanks or Caterpillar tractors, propeller, etc.). In a wider sense, the drive train includes all of its components used to transform stored (chemical, solar, nuclear, kinetic, potential, etc) energy into kinetic energy for propulsion purposes. 2. How to install the drive gear? First, clean the drive gear attaching bolts. Second, remove the adhesive adhered to the threaded holes of the drive gear by turning the special tool, and then clean the treaded holes by applying compressed air. Third, apply the specified adhesive to the threaded holes of the drive gear. Forth, install the drive gear onto the differential case with the mating marks properly aligned. Tighten the bolts to the specified torque in a diagonal sequence. 3. What is the process of the ABS working? The Anti-lock Brake System (ABS) uses a sensor that know when one wheel (or a pair of wheels) is skidding. The sensor sends a signal to a computer, which signals a modulator valve. The modulator connects into the hydraulic system and can momentarily release the brake pressure and prevent the wheels from locking. (The pressure release is so fast that a driver is seldom aware of it.) Pressure is then reapplied until the sensor again sensor that the wheel is about to lock up. Thus, this system keeps the wheels as colse to lock up as possible, without actually allowing the wheels to lock up and skid. This is called incipient lock up. Maximum braking occurs at that point. 4. What is the purpose of gear reduction from steering gear? The gear reduction is known as steering gear ratio. This is needed to reduce the amount of effort required to turn the steering wheel, particularly when parking. During straight-ahead driving, this also reduces the possiblility of oversteering. The ratios vary considerably, depending largely on vehicle size and weight. Larger, heavier vehicles require a graeter reduction in manual steering gears. 5. How does the starter clutch work? The purpose of the starter clutch is to engage and disengage the pinion gear from the flywheel. When the starer is cranking, the pinion gear slides on the armature shaft and engages the flywheel. 6. How to check DTC in the normal mode? First, turn ignition switch off. Second, connect terminals TE1 and E1 of data link connector 1 or 2. Third, Turn ignition switch on. Forth, read the diagnostic trouble code on malfuntion indicator lamp on the combination meter. Fifth, afer completing the check, turn ignition switch off and disconnect terminals TE1 and E1. II. Translate the following into Chinese. (20%) Choose 20 of 30, 1 points for each, total in 20 points. 1. drive train 动力传动系 2. suspension system and axle 悬挂系统和驱动桥 3. brake system 制动系统 4. steering system 转向系统

专业英语考试试题与答案

1.Why are cast metal sheet ingots hot-rolled first instead of being cold-rolled? Because of cold rolling is to use hot rolled steel coils as the raw material, after acid pickling to remove oxide skin for cold rolling, the finished product is hard roll, because of cold work hardening caused by deformation of continuous cold rolling hard roll strength, increase hardness, toughness and plastic index decreased, so the stamping performance will deteriorate, can only be used for simple deformation of the parts 2.What type of heat treatment is given to the rolled metal sheet after hot and “warm” rolling? What is its purpose? 轧钢的热处理的类型？轧钢热处理的目的？ Heat treatment of the main types are annealing, normalizing, quenching and tempering, solution treatment and aging treatment, cold treatment, chemical treatment, etc. Annealing： The steel is heated to a certain temperature and heat preservation for a period of time, and then make it slowly cooling, called annealing. Steel annealing is a heat the steel to the phase change or part of the phase change temperature, slow cooling after heat preservation heat treatment method. The purpose of annealing is to eliminate tissue defects, improve the organization make composition uniformity and fine grains, increase mechanical properties of the steel, reduce residual stress; Can decrease the hardness at the same time, improve the plasticity and toughness, improve machinability. So before annealing in order to eliminate and improve both the legacy of tissue defects and internal stress, and to prepare for the follow-up process, so the annealing is belong to the intermediate heat treatment, also called heat treatment in advance Normalizing： Normalizing is heated to above the critical temperature of steel, to all into homogeneous austenitic steel, heat treatment and natural cooling in air. It can eliminate hypereutectoid steel mesh cementite, for hyposteel normalizing can refine crystal lattice, improve comprehensive mechanical properties, low requirements for the parts use the normalized instead of the annealing process is more economic. Quenching: Quenching is the steel is heated to above the critical temperature, heat preservation for a period of time, then quickly into the quenching medium, the temperature plummeted, rapid cooling at greater than the critical cooling rate of speed, which is mainly composed of martensite and unbalanced heat treatment method of the organization. Can increase strength and hardness of the steel quenching, but to reduce its plasticity. That is commonly used in quenching hardening agent are: water, oil, caustic soda, and salt solution, etc
