What are the car structures? What are the functions and principles of each component?

Automobile structure includes body, engine, chassis and electrical and electronic control. The engine is called the heart of a car. Automobile engines are mainly divided into two mechanisms and five systems, namely crank-connecting rod mechanism and valve train. The five systems mainly include lubrication system, cooling system, ignition system, oil supply system and starting system. Chassis mainly includes transmission system, running system, steering system and braking system. Automobile electrical equipment is mainly composed of battery, generator and braking system. Starter, ignition system, instrument, lighting device, audio equipment, wiper, etc. Among them, batteries and generators are power supply equipment, and others are electrical equipment. The electronic control system mainly includes: electronic fuel injection system, electronic ignition system, idle speed control system, emission control system, air intake control system, supercharging control system, cruise control system, self-diagnosis and alarm system, fault protection system and emergency standby system. In addition to the above control systems, the electronic control system applied to the engine also includes cooling fan control, valve timing control and generator control. These words are too general to be specific. If you are really interested, I suggest you read the book "Automobile Structure", which is about the introductory knowledge of automobiles. ...
