How Often Should a Car's Air Filter Be Replaced?
1 Answers
The air filter should normally be replaced according to the maintenance manual or usage conditions, typically every 10,000-20,000 kilometers or once a year. If the driving conditions involve a lot of dust, it should be inspected and replaced as needed, generally checked every six months. During inspection, clean any debris around the air filter to reduce the buildup of throttle sludge. Function of the air filter: To filter out particulate impurities in the air, ensuring that a sufficient amount of clean air enters the cylinders, preventing airborne dust from being sucked into the engine, which can accelerate wear on the piston group and cylinders. Air filter: It is a type of filter, also known as an air cartridge, air cleaner, or air element. It is mainly used in engineering vehicles, cars, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms as an air filtration device. During operation, the engine inhales a large amount of air. If the air is not filtered, suspended dust particles can be drawn into the cylinders, accelerating wear on the piston group and cylinders. Larger particles entering between the piston and cylinder can cause severe cylinder scoring, especially in dry and sandy working environments. The air cleaner is installed in front of the carburetor or intake pipe to filter out dust and sand particles from the air, ensuring that a sufficient amount of clean air enters the cylinders. Dirty air filter: Using an excessively dirty air filter while driving can restrict engine airflow, leading to incomplete fuel combustion, resulting in unstable engine operation, reduced power, and increased fuel consumption. Therefore, it is essential to keep the air filter clean. The car air filter is a device that removes particulate impurities from the air, consisting of one or several air-cleaning filter components. Its main function is to filter out harmful impurities from the air before it enters the cylinders, reducing premature wear on the cylinders, pistons, piston rings, valves, and valve seats. Thus, air must pass through the fine filtration of the air cleaner before entering the cylinders. A dirty air filter can cause poor engine performance, excessive fuel consumption, and engine damage. When inspecting the air filter, if minimal dust and light clogging are found, it can be cleaned using high-pressure air blown from the inside out and reused. Excessively dirty air filters should be replaced promptly.
