Filter out the air entering the engine combustion chamber without particles and impurities to ensure that the engine intake is clean.There is a lot of dust suspended in the air. The main component is silica, which is a harder substance than metal. The installation of air filters can reduce the wear of cylinders, pistons, piston rings and other parts.The automobile air filter element is installed in front of the carburetor or intake pipe and is used to filter the air entering the engine. The engine sucks in a lot of air during work, and the air contains many dust particles.If it is not filtered through the air filter element, it will cause accelerated wear and tear of the piston group and the cylinder. If larger particles enter between the piston and the cylinder, it will cause the phenomenon of pulling the cylinder.
