★ Inspection and Maintenance of Automotive Air Filters ★

The normal operation of the air filter. It can prevent premature wear (abnormal) of the engine and maintain its working condition. Preventive maintenance of air filters is not an exaggeration. The function of an air filter is to filter out dust, carbon, some water vapor, and other debris from the air before mixing it with fuel, ensuring that clean air enters the cylinder. In theory, for every unit volume of fuel burned, approximately 10000 units of clean air are required. Usually, manufacturers recommend a replacement cycle of 48000 km for normal maintenance of air filters, and conduct a routine inspection every 24000 km; The recommended replacement cycle for its conservative maintenance is 24000 km. The atmosphere contains three types of 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 sandy areas, the inspection and replacement frequency of air filters should be higher. In areas with highways and heavy traffic, due to the concentration of car emissions, the carbon content in the air is significantly higher. For the inspection of the filter, it is necessary to carefully examine the deep wrinkles inside. Sometimes, the exterior of the filter may appear clean, but its interior is already very dirty, and it must be replaced immediately.
