What is the replacement interval for a car's air filter?

[KingAnn]

The air filter is normally replaced according to the maintenance manual or usage conditions, typically every 10,000-20,000 kilometers or once a year. If the driving conditions are dusty, it should be replaced based on inspection results, usually checked every six months. During inspection, clean any debris around the air filter to reduce the formation of throttle sludge. Function of the air filter: It filters out particulate impurities in the air, ensuring that clean air enters the cylinders in sufficient quantities, preventing airborne dust from being sucked into the engine and accelerating wear on the piston assembly and cylinders. Air filter: It is a type of filter, also known as an air filter 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 draws in a large amount of air. If the air is not filtered, airborne dust entering the cylinders can accelerate wear on the piston assembly 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 sufficient and clean air enters the cylinders. Dirty air filter: Using an excessively dirty air filter while driving can restrict engine air intake, leading to incomplete fuel combustion, 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 primary function is to filter out harmful impurities from the air entering the cylinders to reduce early wear on the cylinders, pistons, piston rings, valves, and valve seats. Thus, before air enters the cylinders, it must pass through the fine filtration of the air filter. 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 blockage 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.
