The size of the car maintenance, five oil and three water, replacement of parts and so on, which covers almost 80% of the maintenance and repair of the car. Therefore, as a car owner, it is necessary to understand their specific functions. Xiao Bian summarized 15 common spare parts for everyone. Let's learn together. Five oils: engine oil, transmission oil (gear oil), brake fluid, power steering oil and gasoline; three waters: antifreeze, glass water and battery water.

1. The full name of engine oil is engine lubricating oil. The main function of engine oil is to flow at various positions of the engine that need lubrication when the engine is running, reducing the wear between the various parts of the engine and extending the service life of the engine.

2. Spark plug The spark plug can introduce the high-voltage current in the battery into the cylinder to generate electric sparks to ignite the mixed gas in the cylinder, so that the cylinder starts to work and starts the engine. Each cylinder must be equipped with at least one spark plug, and some models must be equipped with two spark plugs per cylinder.

3. Oil filter element The oil filter element plays a role in filtering out debris, colloids and moisture in the oil, and provides a guarantee for the quality of the oil. Replace when changing the oil.

4. Air filter element The function of the air filter element is to filter the dust suspended in the air when the engine is working to ensure the cleanliness of the intake air. The air filter elements on automobiles are mostly paper materials, and the replacement cycle is about 10000 kilometers. The specific replacement is based on the use environment and usage conditions.

5. Air-conditioning filter element The function of the air-conditioning filter element is to filter the dust and pollen entering the air in the air-conditioning system when the car turns on the air-conditioning element to ensure that the evaporator box and the air in the car are clean.

6. The gasoline filter filters out impurities in the fuel, making the mixture entering the cylinder cleaner, protecting the engine and making emissions more environmentally friendly. It is divided into built-in and external.

7. The role of power steering oil is to make the steering force of the steering wheel easier through hydraulic action when the owner is turning the steering wheel.

8. Glass water, which everyone knows, is used to clean the front and rear windshields or headlights. Glass water is divided into two kinds of glass water in winter and summer. In winter, glass water with lower freezing point is used according to the local temperature. In summer, glass water is mostly used for cleaning and removing glue.

9. Brake fluid, also known as brake booster fluid, is the medium that transmits brake pressure in the brake system. When you step on the brake, the brake fluid generates hydraulic pressure, which pushes air to make the brake pads and the brake disc friction brake, and at the same time Play the role of cooling down.

10. With glass water, wipers must be used to clean the front and rear glass. The wiper needs to be replaced when the wiper is not clean, and the replacement cycle is about 1 year.

11. The battery, also known as the battery, is used to supply power to the car when the car is not started. At present, most cars use maintenance-free batteries. The replacement cycle is 2-3 years, and the price ranges from 300-1000 yuan.

12. Brake pads, also known as brake pads, are the executive parts in the brake system. The quality of the brake pads directly affects the performance of the brakes. When the brake pedal is stepped on, the brake pads will be squeezed on the brake disc or brake drum to prevent the wheels from rotating. Different driving habits will make a huge difference in the wear of brake pads. It is recommended to check and replace them in time.

13. Transmission oil Transmission oil is an oil product that keeps the gearshift system clean, which can ensure the normal operation of the gearbox and extend the life of the transmission device.

14. Antifreeze is also known as coolant. As the name suggests, its main function is to prevent freezing and dissipate heat from the engine. Of course, antifreeze is not equal to water, which into the material can play a role in anti-corrosion, anti-scale.

15. The function of the clutch plate is to transmit power to the transmission. Generally, the clutch plate does not need to be replaced. When the speed increases during acceleration, the vehicle speed is lower than usual, the smell of burnt, jitter, or difficulty in shifting gears, it should be checked and replaced. Summing up the nouns that can be explained in one sentence, I believe you will soon remember that after all, you are dealing with cars every day, and you still need to master these basic knowledge. Perhaps one day, you can also judge where the fault occurred according to the vehicle condition.
