How Often Should the Engine Air Filter Be Replaced?
1 Answers
Replacing the engine air filter is one of the most common routine maintenance tasks. After a certain mileage, it needs to be replaced, typically recommended every 10,000 kilometers or 6 months. Below is more information about the air filter: 1. During operation, the engine draws in a large amount of air. If the air is not filtered, dust particles suspended in the air can enter the cylinders, accelerating wear on the piston assembly and cylinder walls. Larger particles entering between the piston and cylinder can cause severe "cylinder scoring," especially in dry and sandy environments. The air filter is installed at the front of the intake pipe to remove dust and sand from the air, ensuring that clean and sufficient air enters the cylinders. 2. Among the countless components in a car, the air filter is often overlooked because it doesn't directly affect the vehicle's technical performance. However, in practical use, it significantly impacts the lifespan of the car, especially the engine. 3. On one hand, without the filtering effect of the air filter, the engine would inhale large amounts of dust-laden air, leading to severe cylinder wear. On the other hand, if not maintained over time, the filter element can become clogged with dust, reducing filtration efficiency and obstructing airflow, resulting in an overly rich air-fuel mixture and improper engine operation. 4. Generally, it is recommended to replace the air filter every 10,000 kilometers or 6 months, one unit each time. However, maintenance intervals may vary by brand, so the specific replacement schedule should follow the manufacturer's guidelines and consider usage conditions and environmental factors. For example, in areas with severe smog, it's best to replace the filter every 3 months.
