Air filters can be reused, but replacement is recommended. Using compressed air to blow or washing with water can remove thick accumulated dust, but it is difficult to clean the dust trapped inside the paper. The function of an air filter: to filter out particulate impurities in the air, ensuring that sufficient clean air enters the cylinders and preventing floating dust from being sucked into the engine, which accelerates wear on the piston group and cylinders. According to the vehicle's maintenance manual, the air filter should generally be replaced every 10,000–20,000 kilometers or during every other maintenance interval. However, it is recommended to clean the air filter every 5,000 kilometers to reduce the buildup of throttle sludge. The position of the air filter varies depending on the intake system and engine structure, typically located in the air cleaner on the engine's intake pipe. There are two types of air filters in vehicles: dry and wet. Dry filters are made of paper or organic materials, while wet filters are made of wire mesh. Air filter: A type of filter, also known as an air cartridge, air cleaner, or element. It is primarily used in engineering vehicles, automobiles, agricultural machinery, laboratories, sterile operating rooms, and various precision operating rooms. During operation, the engine inhales a large amount of air. If the air is not filtered, the suspended dust particles can enter 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, ensuring sufficient and clean air enters the cylinders. A dirty air filter: Using an excessively dirty air filter while driving can restrict engine airflow, 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 automobile air cleaner is a device that removes particulate impurities from the air, consisting of one or more filter components. Its main function is to filter out harmful impurities from the air before it enters the cylinders, reducing early 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 minor clogging are found, it can be cleaned by blowing high-pressure air from the inside out and reused. Excessively dirty air filters should be replaced promptly.
