What is a car air filter
Central role
Filter impurities : prevent dust, sand and other particles in the air from entering the engine cylinder, avoid abnormal wear of the piston group and cylinder, and prevent the phenomenon of "cylinder pulling".
ensures combustion efficiency : clean air helps fuel to burn fully, avoiding problems such as power drop and fuel consumption increase caused by insufficient intake.
prolonging engine life : the filter element that is not cleaned or replaced for a long time will be clogged, which not only reduces the filtration efficiency, but also may hinder air flow and affect engine performance.
Main types
dry filter : mostly paper or non-woven material, filtration efficiency of up to 99.5% or more, to avoid contact with oil or water, otherwise need to be replaced.
wet filter element : polyurethane material, need to drop oil to enhance adsorption capacity, can be cleaned and reused, but still need to be replaced when serious contamination.
Special material filter : such as 3M polypropylene ultrafine electrostatic fiber filter, can efficiently remove fine dust and harmful gases (such as formaldehyde, benzene, etc.).
Maintenance and replacement
replacement cycle : Usually every 10-20,000 kilometers or each maintenance replacement, but in a dusty environment it is recommended to check or clean every 5,000 kilometers.
maintenance methods : mild dirt can be blown with compressed air, serious dirt need to be replaced; The wet filter element can be treated with cleaning oil.
Installation position : generally located at the front end of the engine intake pipe, the specific varies with the model and intake structure.
Differences from other filters
air conditioning filter : filter the air in the carriage, improve the riding environment, has nothing to do with the engine performance.
oil filter : The impurities in the filter oil belong to the lubrication system parts, the function is different from the air filter.
summary : Air filter is the "first line of defense" of the engine, its performance directly affects the vehicle power, fuel consumption and life. Regular maintenance can significantly reduce the risk of engine failure, it is recommended that the owner strictly follow the maintenance manual operation.
The symptoms and effects of automotive air filter failure include dull engine roar, slow response to acceleration, weak engine operation, too strong mixture, incomplete combustion, abnormally high water temperature, and dense exhaust smoke during acceleration. These symptoms indicate that the air filter may be faulty, and the filter element should be removed in time for maintenance or replacement .
Specific effects of air filter failure on vehicle performance include:
increases engine wear : damage or blockage of the air filter will cause impurities and particles in the air to enter the engine, aggravate the wear of parts and shorten the engine life .
increased fuel consumption : due to insufficient air volume, insufficient combustion, resulting in increased fuel consumption .
power decline : insufficient combustion leads to weakened engine power output and reduced acceleration performance .
excessive exhaust emission inadequate combustion will increase the harmful substances in the exhaust, polluting the environment and endangering health .
Increased maintenance costs : Frequent repairs and replacement of parts increase the cost of vehicle repair and maintenance .
The effect of air filter failure on vehicle fuel consumption is mainly reflected in the increase of fuel consumption caused by insufficient combustion, which increases fuel consumption .
