Unit 1 Automotive BasicsAutomobiles, trucks, and buses are essential forms of transportation. They are complex machines made up of many parts. These parts can be grouped into a number of systems. An understanding of how the system work will help you understand how the automobile works.轿车、卡车和客车是交通运输的重要组成部分。

它们都是由许多部件组成的复杂机器。

这些部件可以归类为汽车的几个组成系统。

了解这些各个小系统是如何工作的将有助于我们理解整个汽车系统是如何工作。

An automobile can be divided into two basic parts: a body and a chassis. The body is the enclosure that houses the engine, passengers, and cargo. It is the part of the automobile that you see. The chassis is that part of the automobile beneath the body.汽车可以分为两个基本部分：车身和底盘。

车身包围发动机、乘客和行李，它是汽车你所看到的部分。

而车身以下的部分就是底盘。

1.1 THE BODY An automobile body is a sheet metal shell with windows, doors, a hood, and a trunk deck built into it. It provides a protective covering for the engine, passengers, and cargo. The body is designed to keep passengers safe and comfortable. For example, insulation in the body reduces noise and protects against heat and cold. The body styling provides an attractive, colorful, modern appearance for the vehicle. It is streamlined to lessen wind resistance and to keep the car from swaying at driving speeds.轿车车身是一个钣金件壳体，它上面有车窗、车门、发送机罩和行李舱门等部件，它给发动机、乘客和行李提供防护。

Unit 1The Basic Structure of an AutomobileToday’s average automobile contains more than 15,000 separate parts that they must work together. These parts can be grouped into four major categories: engine, body, chassis and electrical equipments. The layout of modern automobile is shown as Fig.1.1.Fig.1.1 Layout of a Modern Automobile✩EngineThe engine supplies the power for the vehicle. Most automotive engines are located at the front of the vehicle and drive the wheels through a power train made up of gears, shafts, and other mechanical and hydraulic components. Most automotive vehicles are powered by a four-stroke-cycle internal combustion engine. The in-line four-cylinder engine and V-type six-cylinder engine are the most widely used, with V-8 engines are also common. Some passenger cars and trucks have diesel engines.✩BodyThe automobile body is the assembly of sheet-metal, plastic or composite material panels together with windows, doors, seats, upholstery and other parts.In older vehicle designs, the frame is a separate rigid structure; newer passenger-car designs have the frame and body structure combined into an integral unit.汽车专业英语✩SuspensionThe suspension supports the weight of the vehicle, absorbs road shocks, transmits brake-reaction forces, helps maintain traction between the tires and the road. The springs may be coil, leaf, torsion bar, or air. Most automotive vehicles have coil springs at the front and either coil or leaf springs at the rear.✩SteeringThe steering system enables the driver to turn the front wheels left or right to control the direction of vehicle travel. Steering systems are classified as either manual steering or power steering, with power assist provided hydraulically or by an electric motor.✩BrakeA brake is a device that uses a controlled force to reduce the speed or to stop a moving vehicle, or to hold the vehicle stationary.✩TransmissionThe transmission is the device in the power train that provides different forward gear ratios between the engine and drive wheels, as well as neutral and reverse. The two types of transmission are manual transmission, which the driver shifts by hand, and automatic transmission, which shifts automatically.In power train, the final drive is the speed-reduction gear set that drives the differential. The differential is the gear assembly between axle shafts that permits one wheel to rotate at a speed different from that of the other (if necessary), while transmitting torque from the final-drive ring gear to the axle shafts.✩Electrical EquipmentMost automotive engines have electronic fuel injection instead of a carburetor. A computer-controlled engine managing system automatically manages various emissions devices and engine operation, including the fuel injection and spark timing.NEW WORDS AND PHRASESautomobile[ ♦☜❍☜♌♓●] n. 汽车average [ ✌☜❒♓♎✞] adj. 平均的，普通的，一般的categories[ ✌♦✋♈☜❒♋✋] n. 种类，类别engine [ ♏⏹♎✞♓⏹] n. 发动机body[ ♌♎♓] n. 汽车车身2Unit 1 The Basic Structure of an Automobilechassis[ ☞✌♦♓] n. 底盘layout[ ●♏♓♋◆♦] n. 布局，安排power [ ☐♋◆☜] n. 动力, 功率automotive [ ♦☜❍☜◆♦♓] adj. 有关汽车的; 机动(车)的vehicle [ ♓♓●] n. 交通工具, 车辆power train 传动系gear [♈♓☜] n. 齿轮，传动装置; vt. 齿轮传动；vi.换挡shaft [☞♐♦] n. 轴mechanical[❍♓✌⏹♓●] adj. 机械学的; 力学的hydraulic[♒♋♓♎❒●♓] adj. 液力的，液压的combustion [ ☜❍♌✈♦♦☞☜⏹] n. 燃烧stroke[♦♦❒☜◆] n. 冲程cylinder [ ♦♓●♓⏹♎☜] n. 汽缸passenger [ ☐✌♦♓⏹♎✞☜] n. 乘客truck[♦❒✈] n. 卡车, 载重汽车diesel[ ♎♓☜●] n. 柴油composite[ ❍☐☜♓♦ ♋♓adj. 复合的，合成的♦]material[❍☜♦✋☜❒✋☜●] n. 材料panel[ ☐✌⏹●] n. 仪表板；控制板；面板upholstery[✈☐♒☜◆●♦♦☜❒♓] n. 车身衬里，内饰frame[♐❒♏♓❍] n. 车架rigid[ ❒♓♎✞♓♎] adj. 刚硬的integral[ ♓⏹♦♓♈❒☜●] adj. 完整的, 整体的suspension[♦☜♦☐♏⏹☞☜⏹] n. 悬挂transmit[♦❒✌⏹❍♓♦] vt. 传送brake-reaction force 制动作用力maintain[❍♏⏹♦♏♓⏹] vt. 保持traction[ ♦❒✌☞☜⏹] n. 驱动力tire[ ♦♋♓☜] n. 轮胎spring[♦☐❒♓☠] n. 弹簧coil[ ♓●] n. 线圈，螺旋(弹簧)leaf[●♓♐] n. 叶片torsion[ ♦☞☜⏹] n. 扭转rear[❒♓☜] n. 后部steering[ ♦♦♓☜❒♓☠] n. 转向装置manual[ ❍✌⏹◆☜●] adj. 手动操作的；n. 手册transmission[♦❒✌⏹❍♓☞☜⏹] n. 传动装置, 变速器3汽车专业英语ratio[ ❒♏♓☞♓☜◆] n. 比；传动比neutral[ ⏹◆♦❒☜●] adj. 空挡的reverse[❒♓☜♦] adj. 相反的, 反向的automatic[ ♦☜❍✌♦♓] adj. 自动的automatically [ ♦☜❍✌♦✋●✋] adv. 自动地final drive 主减速器speed-reduction 减速装置differential[ ♎♓♐☜❒♏⏹☞☜●] n. 差速器axle[ ✌♦●] n. 轴，车桥torque[♦] n. 力矩electronic fuel injection 电子燃油喷射carburetor [ ♌☜❒♏♦☜☎❒✆] n. 化油器spark[♦☐] n. 火花timing[ ♦♋♓❍♓☠] n.
