The shape of the body is divided into van type, fish type, boat type, streamline type and wedge type, and the structural form is divided into single box, hatchback and sedan type. Body parts are further divided into covering parts and structural parts. Covering parts refer to body shells, doors, glass, seat decorations, etc.; Structural parts are the basic parts, the chassis of the body, the girders, the vertical and horizontal bars, etc.

The powertrain refers to the combination of four parts of the transmission system, the driving system, the steering system and the brake system on the car, which supports and installs the automobile engine and its various components and assemblies to form the overall shape of the car, bear the engine power, and ensure normal driving.

Electrical and electronic equipment:

1. The power supply system includes a battery, a generator and a regulator. The generator supplies power to the electrical equipment of the whole vehicle and charges the battery at the same time. The role of the regulator is to keep the output voltage of the generator constant.

2. The starting system includes a series excited DC motor, a transmission mechanism, and a control device. Its role is to start the engine.

3. The ignition system includes an ignition switch, an ignition coil, a distributor assembly, a spark plug, etc., which is used to generate a high-voltage electric spark and ignite the mixture in the cylinder of the gasoline engine.

4. The lighting system includes various lights and control devices inside and outside the car. It is used to ensure the safety of driving at night. There are mainly headlights, fog lights, tail lights, brake lights, shed lights, electric horns, turn signal flashers, etc.

5. The signal system includes horn, buzzer, flasher and various driving signal identification lights. It is used to ensure the safety of people and vehicles when the vehicle is running.

6. The instrument system includes various electrical instruments (ammeter, charging indicator or voltmeter, oil pressure gauge, temperature gauge, fuel gauge, speed and odometer, engine tachometer, etc.). It is used to display the working conditions of the engine and the relevant devices in the driving of the car.

7. Auxiliary electrical systems include electric wipers, air conditioners, low-temperature starting preheating devices, tape recorders, cigarette lighters, glass regulators, etc.

Chassis. The chassis consists of a drivetrain, a driving train, a steering system, and a brake system.

The role of the chassis is to support and install the assembly of the automobile engine and its various parts, form the overall shape of the car, and accept the power of the engine, so that the car can move and ensure normal driving. The chassis consists of five parts: transmission system, driving system, steering system, suspension system and brake system. Remember!

A car is usually composed of four parts: engine, chassis, body, and electrical equipment. The engine performs energy conversion and power output. The chassis can accept the power of the engine and drive the drive.

The body serves as a workplace and is used to load goods. Electrical equipment for power supply, ignition and driver assistance. The role of the engine is to make the fuel supplied to it burn and generate power.

Most automobiles use a reciprocating piston internal combustion engine, which is generally composed of a body, a crank connecting rod mechanism, a valve mechanism, a supply system, a cooling system, a lubrication system, an ignition system (used in gasoline engines), a starting system and other parts. The chassis receives the power of the engine, makes the car move, and ensures that the car runs normally according to the driver's control. The body is where the driver works, as well as where passengers and cargo are loaded.

The body should provide convenient operating conditions for the driver, as well as a comfortable and safe environment for passengers or keep the cargo intact. The electrical equipment consists of a power pack, an engine starting system and an ignition system, automotive lighting and signaling devices, etc. In addition, modern cars are increasingly equipped with various electronic devices:

Microprocessors, computer systems and various artificial intelligence devices have significantly improved the performance of automobiles.

Modern automobiles are made up of multiple devices and mechanisms. The basic structure of automobiles produced by different models, different types and different manufacturers is composed of four parts: engine, chassis, electrical equipment and body.
