What is the Replacement Interval for an Air Filter?
1 Answers
According to the vehicle's maintenance manual, the air filter should generally be replaced every 20,000 to 60,000 kilometers. If the driving distance is relatively low, it is recommended to replace it every 12 months. The location of the air filter in a car depends on the intake form and the structure of the engine. There are two types of air filters in cars: dry and wet. Dry filters are made of paper or organic materials, while wet filters are made of metal mesh. The function of the air filter: It filters out particulate impurities in the air, ensuring that a sufficient amount of clean air enters the cylinders. It prevents floating dust in the air from being sucked into the engine, which could accelerate the wear of the piston group and cylinders. Air filter: It is a type of filter, also known as an air filter cartridge, air cleaner, or element. It is mainly used in engineering vehicles, cars, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms as an air filter. During operation, the engine inhales a large amount of air. If the air is not filtered, the suspended dust in the air will be drawn into the cylinders, accelerating the wear of 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 cleaner: Using an excessively dirty air filter while driving can cause insufficient air intake into the engine, leading to incomplete fuel combustion. This results in unstable engine operation, reduced power, and increased fuel consumption. Therefore, it is essential to keep the air cleaner clean. The car air cleaner is a device that removes particulate impurities from the air, consisting of one or several air filter components. Its main function is to filter out harmful impurities from the air entering the cylinders to reduce early wear of the cylinders, pistons, piston rings, valves, and valve seats. Therefore, before air enters the cylinders, it must pass through the fine filtration of the air cleaner. A dirty air cleaner can cause poor engine performance, excessive fuel consumption, and engine damage. When inspecting the air cleaner, if it is found to be lightly clogged with minimal dust, it can be cleaned by blowing compressed air from the inside out and reused. Excessively dirty air filters should be replaced promptly.
