Parts forging manufacturers regularly check to clean the engine inlet has a component called the air filter. Like a mask, it can isolate the impurities in the air, make the air entering the cylinder cleaner, reduce the impact of sand on the cylinder wall and wear, and reduce the wear of piston, piston ring and other parts. Experiments have shown that if the engine is not equipped with air filters, cylinder wear will increase by 68 times; If the air filter is not cleaned in time, the filtration effect will become worse, will accelerate the wear of the cylinder liner.

Air filters need to be cleaned and maintained after about 10,000 km of driving. If the car is temporarily on a muddy, sandy road, usually. We also need to increase the frequency of nursing. Once the air filter is blocked by sand and is not cleaned in time, it is like a nasal cavity with poor breathing. The lack of air entering the engine to participate in combustion leads to incomplete combustion of gasoline, resulting in waste of fuel and generation of carbon accumulation.
