Keep fresh and clean, understand the important role of air filters

If the air is not filtered, the suspended dust in the air will be sucked into the cylinder, which will accelerate the wear of the piston group and cylinder. Larger particles entering between the piston and cylinder can cause serious "cylinder pulling" phenomenon, which is particularly severe in dry and sandy working environments. The air filter is installed in front of the carburetor or intake pipe to filter out dust and sand particles in the air, ensuring sufficient and clean air enters the cylinder.
According to the filtration principle, air filters can be divided into several types: filtration type, centrifugal type, oil bath type, and composite type. At present, the commonly used air filter element in automobile engines is mainly a paper dry air filter. The filter element of the paper dry air filter is made of microporous filter paper treated with resin. The filter paper is porous, loose, and folded, with certain mechanical strength and water resistance. It has the advantages of high filtration efficiency, simple structure, light weight, low cost, and easy maintenance. It is currently the most widely used automobile air filter.
During maintenance, the paper filter element must not be cleaned in oil, otherwise the paper filter element will fail and may easily cause car accidents. During maintenance, only vibration method, soft brush method (brush along its folds) or compressed air back blowing method can be used to remove dust and dirt attached to the surface of the paper filter element. For the coarse filter section, dust should be promptly removed from the dust collection area, blades, and cyclone tubes. Even if the paper filter is carefully maintained every time, it cannot fully restore its original performance, and its intake resistance will increase. Therefore, when the paper filter needs the fourth maintenance, it should be replaced with a new filter. If the paper filter cartridge ruptures, punctures, or the filter paper and end cap come loose, it should be replaced immediately.
When using, it is necessary to strictly prevent the core air filter from being soaked by rainwater, because once the paper core absorbs a large amount of moisture, it will greatly increase the intake resistance and shorten the mission. In addition, paper core air filters should not come into contact with oil or fire.
