What is the Function of a Car Air Filter?
1 Answers
The function of an air filter: It filters out particulate impurities in the air, ensuring that a sufficient amount of clean air enters the cylinders and preventing airborne dust from being sucked into the engine, which could accelerate wear on the piston group and cylinders. According to the car's maintenance manual, the air filter should generally be replaced every 10,000 to 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 location of the car's air filter is determined by the intake system and engine structure, usually found in the air cleaner on the engine's intake pipe. 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. Air filter: It is a type of filter, also known as an air cartridge, air cleaner, or style filter. 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 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 from the air, ensuring that sufficient, clean air enters the cylinders. Dirty air cleaner: Using a dirty air cleaner 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 cleaner clean. The car air cleaner is a device that removes particulate impurities from the air, consisting of one or several air filtration 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 cleaner can cause poor engine performance, excessive fuel consumption, and engine damage. When inspecting the air cleaner, 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.
