With the increasingly serious environmental pollution, the content of inhalable suspended particles in the air is higher and higher. If these suspended particles enter the cylinder of the automobile engine, they will cause a large number of colloidal substances and small wearable particles, affect the combustion adequacy of the automobile engine, and then enter the cylinder and piston in the engine, causing the wear of piston related components, Resulting in the degradation of engine performance.
The main components of the air filter are the filter element and the casing, in which the filter element is the main filtering part, which undertakes the gas filtering work, and the casing is the external structure that provides necessary protection for the filter element. The working requirements of the air filter are to be able to undertake high-efficiency air filtration, not to increase too much resistance for air flow, and to work continuously for a long time.

1.Do not pay attention to quality when buying air filter

Although many car owners now choose 4S stores when replacing the air filter, with an in-depth understanding of the car structure, it is also very simple to replace the car filter by themselves, but whether it is replaced in 4S stores or by themselves, it will involve the purchase of a new air filter. However, at present, many car owners do not have a correct understanding of the role of air filters. They often choose cheap and poor quality air filters. These poor quality air filters have average air filtration capacity, especially for small suspended particles, poor filtration capacity and poor physical stability, The long-term use is bound to lead to the decline of automobile engine performance and a sharp increase in fuel consumption. For example, the manhu air filter in the figure below is obviously clearer than other air filters in terms of volume and appearance. The double-layer structure is very obvious, and the filtering capacity is almost twice that of other brands.

2.Remove the air filter frequently when using the automobile

Some private car owners think that the car air filter can not play much role. After a new car has been used for a period of time, they find that the air filter has been completely blocked. At this time, they simply remove the air filter and do not replace it. As a result, the performance of the automobile engine may not be affected in a short time, but in the long run, the wear of the automobile engine is very serious. Some data show that without automobile air filter, the wear rate of automobile engine cylinder will be more than eight times, the wear rate of piston will be more than three times, and the wear rate of piston ring will be more than nine times.

3.The maintenance of automobile air filter is very rigid and inflexible

Most private car owners also know the importance of replacing the automobile air filter, but when replacing the automobile air filter, they are limited by the automobile maintenance and operation instructions. They can replace the automobile filter according to the mileage provided in the instructions. However, the amount of suspended particles varies with the degree of urban pollution. If you are in a heavily polluted northern city, the replacement and maintenance of the automobile air filter can not be carried out simply according to the instructions. At this time, the automobile state is often obviously abnormal, so you should shorten the maintenance cycle and improve the quality of the automobile filter. This is the correct way of maintenance.
