Car filter: The invisible guardian of the car

In the vast mechanical system of a car, the car filter is like an invisible guardian who makes silent contributions. Although it is not eye-catching, it plays a crucial role in ensuring the normal operation of the car, extending its service life and maintaining the health of the people inside.

Automobile filters mainly include air filters, oil filters, fuel filters and air conditioning filters. The air filter is responsible for filtering the air entering the engine and blocking dust, impurities and particles in the air. When an engine is in operation, it requires a large amount of clean air to be mixed with fuel for combustion. If the inhaled air contains impurities, these impurities will accelerate the wear of internal components of the engine, such as pistons and cylinder walls, leading to a decline in engine performance, weakened power and increased fuel consumption. High-quality air filters can effectively filter out impurities, ensuring that the air entering the engine is clean and pure, providing a guarantee for the efficient operation of the engine. Generally speaking, the replacement cycle of an air filter is 10,000 to 20,000 kilometers, which can be adjusted according to the dust level in the vehicle's driving environment. When driving in a dusty environment, the replacement cycle should be appropriately shortened.

The function of the oil filter is to filter impurities and metal debris from the engine oil. Engine oil circulates inside the engine, serving to lubricate, cool and clean. During this process, the engine oil will adsorb the metal debris produced by the engine operation as well as impurities entering from the outside. If these impurities are not filtered out, they will circulate again with the engine oil, causing severe wear to various components of the engine and even leading to engine failure. The oil filter can promptly intercept these impurities, ensuring the cleanliness of the engine oil, extending its service life, and thus protecting the engine. The oil filter is usually replaced along with the engine oil, typically every 5,000 to 10,000 kilometers. The specific replacement mileage depends on the type of engine oil used by the vehicle and the engine's operating conditions.

The fuel filter is used to filter impurities, moisture and gum from the fuel. During the storage and transportation of fuel, various impurities may be mixed in. After these impurities enter the engine's fuel system, they will clog the fuel injectors, affecting the uniformity and accuracy of fuel injection, leading to incomplete combustion in the engine, reduced power, and may also cause problems such as engine shaking and stalling. The fuel filter can effectively filter impurities from the fuel to ensure the normal operation of the fuel system. The replacement cycle of the built-in fuel filter is relatively long, generally ranging from 30,000 to 60,000 kilometers. The replacement cycle of the external fuel filter is relatively short, approximately 10,000 to 20,000 kilometers.

The air conditioning filter is related to the health of the people in the vehicle. It mainly filters the air entering the vehicle and blocks harmful substances such as dust, pollen, odors and bacteria. When the air conditioning system is in operation, outside air enters the vehicle through the air conditioning filter. If the filter is too dirty or ineffective, these harmful substances will directly enter the vehicle, affecting the air quality inside and causing respiratory discomfort to the driver and passengers, especially for those with allergic constitutions. Regularly replacing the air conditioning filter can create a fresh and healthy air environment inside the vehicle. The replacement cycle of air conditioning filters is generally 10,000 to 20,000 kilometers. In areas with pollen season or frequent smoggy weather, the replacement cycle can be appropriately shortened.

Although automotive filters are just small components of a car, they have a significant impact on the car's performance, reliability and the health of the occupants inside. Regular inspection and replacement of various filters by car owners can keep their vehicles in good condition and ensure a safe and comfortable journey.
