The main components of a car are made up of five basic parts: the engine, chassis, body and electrical equipment, and tires.
The engine is the power plant of the car. It is composed of 2 major mechanisms and 5 major systems: crank connecting rod mechanism, valve system, cooling system, fuel system, lubrication system, ignition system. and the starting system. However, diesel engines have one less ignition system than gasoline engines.
The chassis consists of a transmission system, a driving system, a steering system and a braking system.
The body is installed on the chassis frame and is used by drivers and passengers to mount or load goods. The body of passenger cars and buses is generally an integral structure, and theA truck's body generally consists of a cabin and a cargo box.
Electrical equipment consists of two main parts: power supply and electrical equipment. Electric power includes batteries and generators; Electrical equipment includes engine starting system, gasoline engine ignition system and other electrical devices.
Tires are one of the important parts of the car. They are in direct contact with the road and work with the car suspension to mitigate the impact of the car while driving, thus ensuring good driving comfort. and a smooth ride.
