01. The function of the air filter

The automotive air filter is located in the engine’s air intake system and is an assembly consisting of one or several filter components used to purify the air. Its main function is to filter out harmful impurities in the air entering the cylinder, thereby reducing the early wear of the cylinder, piston, piston ring, valve and valve seat.

02. The influence of air filter on the engine

The state of the air filter is related to the life of the engine and is also closely related to the fuel consumption of the car. So what should I pay attention to when using air filters?

(1) If it is found that the engine is working unstable, when you continue to press the accelerator pedal, the engine sound is muffled, the acceleration response is slow, the operation is weak, and the car exhaust is thick and black, then the air filter needs to be replaced.

(2) Check the surface color of the air filter element of the air filter. If the filter paper on the surface of the air filter element is gray-black, it means that the filter element can no longer be used and should be replaced immediately.

03. How often should the air filter be replaced

Under normal road driving conditions, it takes about 10,000 ~ 12,000 kilometers or a year to replace the air filter, but the maintenance cycle of the car air filter is different in different environments. In areas with a lot of dust and humid surrounding air, the maintenance interval should be shortened accordingly, and it is best to check the use of the air filter once.

Some car owners with strong hands-on ability can also open the air filter assembly to check the surface condition of the filter. Let’s talk about how to install and remove an air filter.

04. The position of the air filter

Stop the fire: Open the engine cover when the car is cold and find the position of the air filter assembly. In general, the air filter is located on the right side of the engine compartment. Please refer to the location markings in the vehicle manual for details.

Remove the filter element: open the lock of the filter cover, remove the nut that holds the cover, pull the baffle and remove the filter element.

Check the filter element: Check whether there is more dust in the filter element and gently pat the end face of the filter element. If the filter element is still clean and does not need to be replaced, it can be installed and used again (removing the filter element will not affect the use).

Install the filter element: clean the dust on the surface of the air filter assembly, then put the filter in the modeling direction, pay attention to the positive and negative directions, and finally close the lid, buckle or screw on.
