Today we will learn about the four major components of an automobile through a bilingual comparison: the engine (engine system), body, chassis, and electrical equipment. While mastering the basic knowledge of automobiles, we will also include some bilingual vocabulary from the Automotive Industry Information Network. Everyone is also welcome to study automotive interpreting and translation systematically with us.
Today’s average car contains more than 15,000 separate, individual parts that must work together. These parts can be grouped into four major categories: engine, body, chassis, and electrical equipment.
Today’s ordinary cars consist of about 15,000 separate components. These components are divided into four categories: engine (engine system), body, chassis, and electrical equipment.

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.
The engine is the component that generates power. The internal combustion engine is the most common. The engine obtains energy by burning liquid gasoline in its cylinder (converting the energy of gasoline into kinetic energy to drive the car). Engines are divided into gasoline (spark-ignition) engines and diesel (compression-ignition) engines. Both types of engines are referred to as heat engines. The burning gasoline generates heat, which increases the gas pressure inside the cylinder, thereby providing energy to rotate the transmission shaft.
Body 车身
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. The body styling provides an attractive, colorful, modern appearance for the vehicle.
The automobile body is composed of a metal sheet shell, windows, doors, a hood, and a trunk lid. The body provides a protective cover for the engine, passengers, and cargo. The design of the body should follow the principle of ensuring passenger safety and comfort. The styling of the body gives the car an attractive, colorful, and modern exterior.
Chassis 底盘
The chassis is an assembly of those systems that are the major operating part of a vehicle. The chassis includes the transmission, suspension, steering, and brake systems.
The chassis is assembled from the main operating systems of the automobile. It includes the transmission, suspension, steering, and brake systems.
Transmission systems convey the drive to the wheels. The main components are clutch, gearbox, drive shaft, final drive, and differential.

Electrical Equipment 电气设备
The electrical system supplies electricity for the ignition, horn, lights, heater, and starter. The electricity level is maintained by a charging circuit.
