2. When the air filtering fails and is not replaced in time, serious irreversible adverse effects can be caused on an engine and the like. If an air filter element in the air inlet system fails, air entering the air cylinder may carry fine sand, particles or other incombustible foreign matters, which may cause abrasion or damage to the cylinder wall, the piston ring and the air valve, and in severe cases, if larger particles enter between the piston and the air cylinder, cylinder scuffing may occur.
