Among the tens of thousands of parts and components of the car, the air filter is a very inconspicuous component, because it is not directly related to the technical performance of the car, but in the actual use of the car, the air filter is (Especially the engine) has a great impact on the service life. On the one hand, if there is no filtering effect of the air filter, the engine will inhale a large amount of air containing dust and particles, resulting in serious wear and tear of the engine cylinder; on the other hand, if the air filter is not maintained for a long time during use, The filter element of the cleaner will be filled with dust in the air, which will not only reduce the filtering capacity, but also hinder the air circulation, resulting in excessively thick air mixture and abnormal operation of the engine. Therefore, regular maintenance of the air filter is essential.

Air filters generally have two types: paper and oil bath. In recent years, paper filters have been widely used due to their advantages of high filtration efficiency, light weight, low cost, and convenient maintenance. The filtration efficiency of the paper filter element is as high as over 99.5%, and the filtration efficiency of the oil bath filter is 95-96% under normal conditions. At present, the air filter widely used in cars is a paper filter, which is divided into two types: dry type and wet type. For the dry filter element, once it is immersed in oil or moisture, the filtration resistance will increase sharply. Therefore, avoid contact with moisture or oil when cleaning, otherwise it must be replaced with a new one.

When the engine is running, the air intake is intermittent, which causes the air in the air filter housing to vibrate. If the air pressure fluctuates too much, it sometimes affects the engine’s air intake. In addition, the intake noise will also be increased at this time. In order to suppress the intake noise, the volume of the air filter housing can be increased, and some partitions are also arranged in it to reduce resonance.

The filter element of the air cleaner is divided into two types: dry filter element and wet filter element. The dry filter element is made of filter paper or non-woven fabric. In order to increase the air passage area, most of the filter elements are processed with many small wrinkles. When the filter element is slightly contaminated, it can be blown with compressed air. When the filter element is severely contaminated, it should be replaced with a new one in time.

Maintenance

1. The filter element is the core component of the filter. It is made of special materials and is a vulnerable part that requires special maintenance and maintenance;

2. After the filter has been working for a long time, the filter element in it has blocked a certain amount of impurities, which will cause an increase in pressure and a decrease in flow rate. At this time, it needs to be cleaned in time;

3. When cleaning, be careful not to deform or damage the filter element.

Generally, the service life of the filter element is different according to the different raw materials used, but as the use time increases, impurities in the water will block the filter element, so generally the PP filter element needs to be replaced in three months; the activated carbon filter element needs to be replaced in six months ; As the fiber filter element cannot be cleaned, it is generally placed on the back end of PP cotton and activated carbon, which is not easy to cause clogging; the ceramic filter element can usually be used for 9-12 months.
