PAGE \* MERGEFORMAT 1 Unit 1 Automotive Basics Automobiles, 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。车身设计来确保乘客乘坐的安全和舒适。比如：车身绝热层可以减少噪音和抵御冷热。车身造型设计使得汽车有一个华美、现代、吸引人的外观。车身的流线型设计可以减少风阻，防止汽车行驰过程中发生摆动。 The automobile body has two basic parts-the upper body and the under body. 车身有两个基本部分-车身上部和车身下部。 1.2 The chassis The chassis is an assembly of those systems that are the major operating parts of a vehicle. The chassis includes everything except the body. The three important parts of the chassis are the frame, the engine, and the power train (also called the drive train). Each of these three parts is made up of a number of systems. A system is a mechanical or electrical unit that performs a specific function. Thus, each system (such as steering, brake, or fuel) has a certain job to do in running a vehicle.
