How many car filter elements are there?How often is the best time to change the car filter?

There are 4 car filter elements, namely oil filter element, fuel filter element, air filter element, air conditioning filter element, and filter element is also called filter.

1. Oil filter

The oil filter element is installed in the oil passage. During the circulation process, the oil is first filtered through the filter element and then flows to various parts that need lubrication. In order to remove impurities in the oil, the filter can better lubricate the surface of the parts and reduce friction.

The life of the oil filter element is related to the material, filter area, and strength of the filter paper. The better the material of the filter paper and the stronger the filter area, the longer the life of the oil filter element. Generally, the life of the oil filter element is 5000-8000 kilometers, up to 25000 kilometers. , It is necessary to make a comprehensive judgment based on the quality of the oil filter element, the habits of the vehicle, the wear condition of the vehicle, and the quality of the oil.

2. Fuel filter

The fuel filter element is to filter the gasoline that is about to be burned, filter out the impurities in the gasoline, so that the gasoline can better participate in the combustion, and increase the fuel usage rate. Generally, the service life of the fuel filter element is 10,000 kilometers, and it needs to be replaced on time. After using it to a certain extent, it will affect the fuel filtration and the oil pressure will drop.

3. Air filter

The air filter element filters the gas entering the engine and filters out the impurities in the air, because the impurities entering the cylinder will cause abnormal wear of the cylinder and shorten the service life of the engine. The life cycle of the general air filter element is 10,000 to 20,000 kilometers. It is greatly affected by the driving environment, if the environment is poor, it needs to be replaced in advance.

4. Air conditioning filter

If the air conditioner filter element is dirty, the air output of the air conditioner will be reduced, and it will not be cool in summer or warm in winter, and it may even breed bacteria and affect the occupants in the car. The air conditioner filter element needs to be replaced frequently. Generally, it is best to change the seasons in autumn and winter, spring and summer, and replace when the air conditioner is needed.
