中英图文对照汽车技术解析

1.1 Principal Components 主要构成零部件
Today's average car contains more than 15,000 separate, individual parts that must work together. These parts can grouped into four major categories: engine, body, chassis and electrical equipment. 现在，一般汽车由大约一万五千多个独立的零部件组成。这些部件分为四大类，即发动机（引擎系统），车身，底盘和电气设备。

1.2 Engine 发动机/引擎系统
The engine acts as the power unit. The internal combustion engine is most common: this obtains its power by burning a liquid fuel inside the engine cylinder. There are two types of engine :gasoline(also called a spark-ignition engine) and diesel(also called a compression-ignition engine).Both engines are called heat engines; the burning fuel generates heat which causes the gas inside the cylinder to increase its pressure and supply power to rotate a shaft connected to the transmission.
引擎的作用是动力产生的部件。内燃机引擎最为常见。引擎通过燃烧其汽缸内的液体汽油来获得能量（将汽油的能量转化为动能来驱动汽车）。引擎分为汽油（火花引燃式）发动机和柴油（压燃式）发动机。 这两类发动机都被称为热力机。燃烧的汽油产生热量，促使汽缸内的气体气压增强，从而提供能量以旋转（启动）传输轴。
