The function of the air filter element is to filter out particulate impurities in the air, and it is installed in the intake pipe, at the front end of the air flow meter. When the engine is working, it needs to inhale a large amount of outside air. The "inhalable particulate matter" in the air is filtered out by the air filter element, and then enters the cylinder (or air intake) to mix with fuel for combustion. If the air filter element does not perform its proper filtering function, larger particles in the air will enter the engine for combustion, which will cause various "faults" over time.
The function of the Auto Air Filter is to filter out particles and impurities in the air entering the combustion chamber of the engine, so as to ensure that the intake air of the engine is clean. There is a lot of dust suspended in the air, the main component is silicon dioxide, which is a substance harder than metal. Installing an Auto Air Filter can reduce the wear of parts such as cylinders, pistons and piston rings. The Auto Air Filter is installed in front of the carburetor or the intake pipe, and is used to filter the air entering the engine. The engine needs to suck in a lot of air during operation, and the air contains a lot of dust particles. If it is not filtered by the air filter element, it will cause accelerated wear of the piston group and the cylinder. If larger particles enter between the piston and the cylinder, it will cause cylinder scuffing.
