When does the car filter element need to be replaced?


    The nose of a car-air filter: The air filter of a car is equivalent to a human nose. It is the first "checkpoint" through which air enters the engine. Its function is to filter out sand and some suspended particles in the air. So that the air entering the engine is relatively pure so that the engine can work normally. In February, winter will come to spring. Generally speaking, the air in spring will contain relatively more dust and sand. The air filter is prone to clogging. At this time, the engine will be difficult to start, weak in acceleration, and not idling. If the symptoms are stable, it is very necessary to clean the air filter once. The normal operation of the air filter can avoid premature wear (abnormal) of the engine and maintain a better working condition.

    The car air filter is an article that removes particulate impurities in the air in the car. The car air conditioning filter can effectively reduce the entry of pollutants into the car through the heating, ventilation, and air conditioning system, and prevent the inhalation of harmful pollutants.

    The car air filter can bring a cleaner car environment to the car. Automobile air filter belongs to automobile products, which is composed of filter element and shell. The main requirements are high filtration efficiency, low flow resistance, and continuous use for a long time without maintenance.

    The automobile air filter is mainly responsible for removing particulate impurities in the air. When piston machinery (internal combustion engine, reciprocating compressor, etc.) is working, if the inhaled air contains dust and other impurities, it will aggravate the wear of the parts, so an air filter must be installed. The air filter consists of two parts: a filter element and a shell. The main requirements of an air filter are high filtration efficiency, low flow resistance, and continuous use for a long time without maintenance.

    Automobile engines are very precise parts, and very small impurities can damage the engine. Therefore, before the air enters the cylinder, it must pass through the fine filtering of the air filter before entering the cylinder. The air filter is the patron saint of the engine, and the quality of the air filter is related to the life of the engine. If a dirty air filter is used in a car, it will cause an insufficient intake of the engine and incomplete fuel combustion, resulting in unstable engine operation, decreased power, and increased fuel consumption. Therefore, the car must keep the air filter clean. The engine has three kinds of filters: air, oil, and fuel. The air-conditioning filter in the car is generally called "four filters." They are respectively responsible for the filtration of media in the engine air intake system, lubrication system, and combustion system cooling system.

    The atmosphere contains three basic particulate pollutants with different densities, namely dust, residue, and carbon particles. On open highways, the dust content is lower than in rural and built-up areas. In areas with high dust concentration, such as construction sites and wind-sand areas, the frequency of inspection and replacement of air filters is higher. In expressways and traffic-congested areas, because car emissions are concentrated, the content of carbon particles in the air is significantly higher. For the inspection of the filter, you should carefully check the deep inside the folds. You can often blow the filter element with the high-pressure wind. Sometimes, the outside of the filter looks clean, but the inside is already very dirty and must be replaced immediately.
