What are the main components of an automobile's overall structure?
1 Answers
Common automobiles are generally composed of four main parts: the engine, chassis, body, and electrical equipment. The specific functions of these four major components are as follows: Engine: The engine is the power unit of an automobile. Its function is to generate power by burning fuel, which then drives the wheels through the drivetrain of the chassis to propel the vehicle. There are mainly two types of engines: gasoline engines and diesel engines. A gasoline engine consists of the crankshaft-connecting rod mechanism, valve train, fuel supply system, cooling system, lubrication system, ignition system, and starting system. Diesel engines use compression ignition, so they do not have an ignition system. Chassis: The chassis serves to support and mount the automobile engine and its various components and assemblies, forming the overall shape of the vehicle. It also receives power from the engine to enable the car to move and ensure normal operation. The chassis is composed of four parts: the drivetrain, running gear, steering system, and braking system. Body: The body is mounted on the frame of the chassis and is used to accommodate the driver, passengers, or cargo. The body of a passenger car or bus is usually a unitary structure, while the body of a truck generally consists of two parts: the cab and the cargo compartment. Electrical Equipment: The electrical equipment consists of two main parts: the power source and the electrical devices. The power source includes the battery and generator. The electrical devices include the engine's starting system, the ignition system of gasoline engines, and other electrical appliances.
