Vehicle maintenance, we most often contact is to replace the oil filter

Oil filters are divided into two types, one is shell/core integrated; the other is shell/core separate type. Irregular replacement of unqualified inferior air filters is a device for purifying the air. If the dust, sand particles and various impurities in the air directly enter the air filter, there are two types: dry type and wet type. The dry type is the most commonly used on car models. Its material is filter paper or non-woven fabric. In order to increase the air through the area, the filter element is mostly processed with many small folds. When the filter is slightly contaminated, compressed air can be used to blow it off. When the filter is severely contaminated, a new core should be replaced in time. Generally speaking, there is no accurate replacement time for the air filter. It is determined according to the environment in which the vehicle is used, but the replacement time is no more than 1 year, and the vehicle driving distance is no more than 15000 kilometers. The position of the air filter in the car is generally behind the front air intake grille. You can check the air filter yourself when you are in the car. If you find it is dirty, you can take it out and clean it or replace it.

Problems that will occur if the air filter is replaced irregularly

If the filter is severely blocked, the air intake resistance will increase,

In addition, the service life of the inferior air filter is also very low. Generally, it will be very dirty after a few hundred kilometers and the inferior filter will increase the air intake resistance,

I just talked to you about the air filter. Let me talk to you about the air-conditioning filter. Its function is to filter the outside air to ensure that the air in the car is fresh and free of peculiar smell. To sum up, the air-conditioning filter has the following functions:

Ensure that unfiltered air enters the cabin as little as possible.

2. Filter solid impurities such as dust and abrasive particles in the air.

3, adsorption of harmful substances and moisture in the air.

4. Ensure that the air in the passenger room is clean and does not breed bacteria, can effectively intercept pollen, and ensure that the drivers and passengers will not have allergic reactions and affect driving safety.

Problems that will occur if the air conditioner filter is not replaced

The function of the air-conditioning filter element is to filter the air, but after long-term use, the air volume that the air-conditioning filter element can filter is reduced. At this time, when we use the air-conditioning system, we may feel that the wind blowing from the air outlet is not so strong or not so strong; in addition, in a humid environment, The air-conditioning filter element is also prone to mold and breed bacteria, which leads to mildew or odor when using the air-like. In addition, there may be activated carbon in the air-conditioning filter element, and the adsorption and filtering function of activated carbon will be reduced after long-term use. Therefore, the air-conditioning filter element needs to be replaced regularly, generally once a year.

The consequences of using unqualified and inferior air-conditioning filters. Inferior air-conditioning filters are difficult to filter out impurities due to rough workmanship and low material quality. Moreover, inferior air-conditioning filters use ordinary paper, so the quality is very Poor and easy to produce mold, which is very harmful to your body when you use the air conditioner. With the air filter, the position of the air-conditioning filter in the car is generally in the passenger's glove box in the car. The disassembly is also relatively good. You can check it yourself when you use the car. In addition, it should be noted here that some cars do not have air-conditioning filters installed in the original factory (such as JEEP series models), but these models that do not have air-conditioning filters installed at the factory have installation positions.

The function of the fuel filter is to remove the solid impurities contained in the fuel to prevent the fuel system from clogging (especially the built-in fuel filter. There are two types of fuel filters: one is external, generally located The lower part of the chassis; the other is a built-in type, located in the fuel tank. The two are only different from the installation position, and the effect is still the same. In addition, the external type is divided into ordinary straight into direct type and with two kinds of oil return pipeline. For different vehicles, the replacement cycle of the fuel filter is different. It is generally recommended to replace the fuel filter every 50000-70000 kilometers. If the fuel quality is not good, the replacement cycle can be shortened. Problems that will occur when the fuel filter is replaced irregularly. The function of the fuel filter is to filter impurities in the fuel, but after long-term use, the inside of the fuel filter may be blocked by impurities and affect the fuel supply, resulting in fuel supply. Reduce the difficulty of starting the engine. In addition, long-term blockage of the fuel filter will cause premature damage to the gasoline pump.
