When it comes to auto parts, I understand some basic information and key takeaways. The following is a detailed introduction to auto parts:

1. Classification

Auto parts can be classified in a variety of ways, including but not limited to:

Functional Classification:

Power unit: Like the engine, it is the heart of the car and converts the thermal energy of the fuel into mechanical energy.Transmission system: including clutch, transmission, transmission shaft, etc., which is responsible for transmitting the power of the engine to the wheels.Driving system: including frame, axle, suspension, wheels, etc., to support the quality of the whole car and ensure the driving of the car.Steering system: including steering wheel, steering gear, etc., which is used to control the direction of travel of the car.Braking system: including brake pads, brake discs, brake fluid, etc., which are used to slow down or stop.Body: including engine cover, roof cover, trunk cover, etc., the main role is to protect the driver and passengers, and constitute a good aerodynamic environment.Electrical system: including generators, batteries, lighting equipment, etc., to provide electricity and lighting for the car.

Classification of production sources:

Original parts: Produced by the supporting factory designated by the automobile factory, which is exactly the same as the assembly of the automobile when it leaves the factory.

Analogues: Produced by the original parts manufacturer, but without the accessories marked by the car manufacturer, the quality is similar to the original parts, but the price is lower.

Factory accessories: Accessories that are not authorized by the car manufacturer and have their own independent trademarks, and the quality level is difficult to directly compare with the original parts.

Counterfeit and shoddy parts: counterfeit parts are imitation parts that completely imitate the packaging and trademark of the original parts; Counterfeit parts are low-quality parts whose use can lead to serious safety incidents.

2.the introduction of key components

Engine: It is composed of the body, crank connecting rod mechanism, valve mechanism, etc., and is the power source of the car.

Brake system: including brake pads, brake discs, brake fluid, etc., is a key component of the car to slow down and stop. The life of brake pads is affected by factors such as vehicle model, vehicle weight, driving habits, etc., and needs to be checked and replaced regularly.

Tire: is the part of the car that is in contact with the ground and bears the weight of the vehicle and provides grip. The replacement cycle of tires is usually 5 years or 6~80,000 kilometers, but it also needs to be judged according to the use environment, car habits and wear degree.

Battery: Provides electricity to the car and starts the engine. The life of the battery is usually 3~5 years, and the power and working status need to be checked regularly.

Suspension system: including shock absorbers, springs, etc., which are responsible for supporting the weight of the vehicle and absorbing road vibrations to maintain the stability of the vehicle. The life of the shock absorber is usually about 100,000 kilometers, and if an oil leak is found, it should be replaced in time.

3. Maintenance and maintenance

The care and maintenance of auto parts is essential for the performance and longevity of the car. Here are some common care and maintenance recommendations:

Regular inspection: Regularly inspect auto parts, including brake systems, tires, batteries, suspension systems, etc., to ensure that they are in good working order.

Timely replacement: For parts with serious wear, such as brake pads and tires, they need to be replaced in time to avoid safety accidents.

Keep it clean: Regularly clean auto parts, such as air filters, cabin air filters, etc., to prevent dust and impurities from entering and affecting performance.

Use high-quality parts: Choose high-quality parts for replacement and repair to extend the life of your car and improve performance.

4.the replacement cycle and precautions

The replacement cycle for different auto parts varies depending on factors such as the model, the environment in which it is used, and the driving habits. Here are some common parts replacement cycles and considerations:

Oil and oil filter: mineral oil is changed every 5000 km or half a year; Semi-synthetic oil is changed every 7,500 km or eight months; Fully synthetic motor oil is changed every 10,000 km or a year. The oil filter should be changed at the same time as the oil.

Brake fluid: Replace every 2 years or 60,000 kilometers, which is greatly affected by environmental humidity, and needs to be checked regularly and replaced in time.

Spark plugs: different types of spark plugs have different replacement cycles, such as the ordinary spark plugs of EFI machines are replaced every 30,000 kilometers; The platinum spark plug of the direct injection machine is replaced every 40,000 km.

Tires: Usually require 5 years or 6~80,000 kilometers to replace, but it also needs to be judged according to the use environment, car habits and wear degree.

To sum up, auto parts are an important part of the car, and their performance and life directly affect the overall performance and safety of the car. Therefore, we need to regularly inspect and maintain auto parts to ensure that they are in good working order.
