There are four kinds of filters in a car.
1. Oil filter.
The oil filter is integrated into the engine oil passage. During the circulation of engine oil, the oil first passes through the filter for purification before flowing to all parts that require lubrication. Filtration removes impurities from the engine oil, allowing for better lubrication of component surfaces and reducing friction.
2. Fuel filter.
The fuel filter filters the gasoline before combustion, removing impurities from the gasoline to ensure cleaner fuel enters the combustion chamber, thereby improving fuel efficiency.Generally, the fuel filter should be replaced every 10,000 to 20,000 kilometers. After prolonged use, its filtering performance will deteriorate, resulting in reduced fuel pressure.
3. Air filter.
The air filter filters the air entering the engine, removing impurities from the air. Impurities entering the cylinders can cause abnormal wear and reduce the service life of the engine. Generally, the service life of an air filter is 10,000 to 20,000 kilometers. It should be replaced earlier if the vehicle is operated in harsh environments.
4. Cabin filter.
A dirty cabin air filter will reduce the air output of the air conditioning system, leading to poor cooling in summer or insufficient heating in winter. It may even breed bacteria and harm the health of passengers inside the vehicle. It is recommended to replace the filter during seasonal transitions between spring and summer, and between autumn and winter.
