What is a filter? What is it used for?

When it comes to car filters, I believe that experienced drivers with strong hands-on skills must have replaced their own filters. Machine filters and air conditioning filters are all familiar to experienced drivers. However, for novice drivers or friends who don't touch water, it's quite difficult. What is automatic filtering? What is it used for?

Apart from the two mentioned earlier, there are four types of filters commonly used in cars, namely steam filters and air filters, which are the two most important ones today. The machine filter element and air conditioning filter element have both been mentioned before. You can click on this one specifically: These items do not need to be used by the original factory. Replacement guide for car filter elements.

Gasoline filter

If there is an oil filter, there must be a gasoline filter. The steam filter filters impurities from the fuel to provide clean fuel for the engine. Gasoline itself is not absolutely pure and is prone to generating impurities during the production of storage and transportation projects. If it is not filtered out and carried into the engine fuel supply system, it is very likely to damage the fuel pump or clog the fuel injectors.

If the gasoline filter is too dirty or clogged, it will lead to increased fuel consumption, unstable idle speed, and reduced power, etc. It is recommended that you strictly follow the car maintenance manual for replacement.

Air filter

Many people confuse air filters with air conditioning filters, but in fact, their specific functions are different. The air conditioner filters the outside air into the vehicle through the air conditioning system, and the air filter filters the air that needs to be burned into the engine.

There are many invisible impurities in the air, such as dust and particles. If they enter the engine and participate in combustion without being filtered, carbon deposits are very likely to occur.
