The air filter can remove the particulate impurities in the air. If the inhaled air contains dust and other impurities when the engine is working, it will aggravate the wear of various parts and reduce their service life. Although it is now advocated to take the road of green development, as far as the current environment is concerned, the pollution is still very serious, and the content of inhalable suspended particles in the air is relatively high. Once these substances enter the cylinder of the engine, the gasoline will not be fully burned, causing the engine efficiency to decline. Therefore, the existence of the air filter is to make a filter barrier before the air enters the cylinder to isolate the particles in the air from the cylinder. At the same time, it can ensure sufficient air intake to ensure the power of the engine without damage.

1、 The maintenance is inflexible and rigid
Many car owners know the importance of replacing the air filter. They strictly follow the provisions of the car maintenance instructions and look at the mileage provided above to replace it. But what you don't know is that the content of particulate matter in the air varies according to the degree of air pollution in each city. Especially in northern cities, the maintenance and replacement of air filters can't be carried out completely according to the maintenance book. By then, the driving of cars will have been abnormal. Therefore, it is necessary to shorten the maintenance and replacement cycle and improve the quality of air filters, This is the correct maintenance method.

2、 Remove it without replacing it
Some car owners think that the role of the air filter is not very obvious. After using it for a period of time, they will remove it and will not replace it with a new one. In this way, although the driving of the car will not be affected in a short time, the wear of the engine will be very serious in the long run. According to relevant data, for engines without air filters, the wear rate of cylinders will increase by 8 times, the wear rate of pistons will exceed 3 times, and the wear rate of piston rings will exceed 9 times.

3、 I didn't care about the quality of the air filter when I bought it
When the car owners just bought the car, they would choose to replace the air filter at the 4S store. However, with the increase of time and understanding of automobile knowledge, I will replace the air filter by myself, because it is not difficult to replace it. But this involves the purchase of a new air filter. At present, many car owners do not know the importance of air filter very well. When choosing it, they often choose the one with low price, but the one with low price is often of poor quality. The ability to filter particles in the air is also average. Long term use will reduce the function of the engine, increase fuel consumption and reduce the service life of the engine.

The air filter is one of the core components of the four filters of the automobile. When purchasing it, you must choose the one with excellent quality. When using it, you must regularly maintain and replace it. According to the different driving environment of the vehicle, you must carry out targeted maintenance and replacement, so as to effectively ensure its working efficiency and protect the engine.
