Will the air conditioner filter be too loud if it is not changed for a long time?

There will be. Impact:

1. Air filter: The air filter can block the dust and road dust that enter the engine, and these hard particles will cause internal wear and tear of the engine, cause scratches on the surface of the cylinder, adsorb on the surface of the closely matched parts, and cause surface wear of exposed and lubricated parts.

2. Air conditioner filter:

The main ingredient in air/conditioning filters is activated carbon.

Activated carbon is a highly efficient adsorption material, as early as the "First World War."

, it is applied to gas masks. And now activated carbon.

It is widely used for air purification in automobiles and indoors. Activated carbon is a porous carbonaceous substance with a well-developed pore structure that gives it a large surface area.

Therefore, it is easy to fully contact with the toxic and harmful gases in the air, and the strong adsorption force field around the activated carbon hole will immediately suck the toxic gas molecules into the hole, so the activated carbon has a strong adsorption capacity.

If you don't change it for a long time, the filter element loses its due effect, which directly affects the air quality in the cab.

Replacing the air conditioner filter for a long time will not cause the engine to overblow, because the air conditioner filter is activated carbon, and if it is not replaced for a long time, it will only affect the cooling and heating effect of the air conditioner. If your engine has abnormal noise, it is recommended to go to a 4S shop for inspection.

If the air conditioning filter is not changed for a long time, it will not cause the engine to be too loud, but it will cause odors in the car, air quality will decrease, and bacteria will increase. It is recommended to change the use environment (such as whether it often passes through the dust road) and the frequency of use. If you don't use the air conditioner often, of course, you can deal with it if you don't change it for a long time.

There is a sound after the air conditioner filter is replaced, it should be a foreign object that went in when it is replaced, take it apart and check it, or take the air conditioner filter down to see if there is still an abnormal sound, if there is no indication that the air conditioner filter is not of good quality, it should be replaced with a new filter.

After changing the air conditioner filter in a stupid state, the sound will become louder. The function of the air conditioner filter:

1. It can make the air conditioner lattice close to the shell to ensure that the unfiltered air will not enter the cabin;

2. It can separate solid impurities such as dust, pollen, and abrasive particles in the air;

3. It can adsorb water, soot, ozone, odor, carbon oxide, SO2, CO2, etc. in the air; Strong and long-lasting water adsorption;

4. It can make the car glass not covered with water vapor, so that the driver and passengers have a clear line of sight and driving safety; It can provide fresh air to the driver's cabin, avoid the driver and passengers from inhaling harmful gases, and ensure driving safety; It can effectively sterilize and deodorize;

5. It can ensure that the air in the driving and passenger compartment is clean and does not breed bacteria, and create a healthy environment; It can effectively separate the impurities in the air, such as dust, core powder, and abrasive particles. It can effectively intercept pollen and ensure that the driver and passengers will not be allergic to the wheel response and affect the driving safety. (Photo by Li Linwei) @2019

The reason for the sound after the replacement of the air conditioning filter element is due to the sound of the engine compartment, the engine has a sound marking symbol, and the technical status of a certain mechanism of the engine has changed, the key is because some parts are worn out or even installed and adjusted improperly.

The abnormal sound of the gearbox indicates that if there is a "rustle" sound inside the gearbox while the car is driving, and there is no other sound after pressing the clutch or accelerator, there will be a sound similar to whistling when changing gears.

After the air conditioner filter is replaced, there is a sound because the car width is wide

1. There will be quite a lot of noise in the engine compartment, and the vast majority of people also judge that it is the sound of the engine compartment based on the sound, and it will generally be a metal screech or a whistling sound;

2. The solution: the engine has a sound mark, and the technical status of a certain mechanism of the engine has changed. The key is that some parts are worn out too skillfully or the installation configuration and adjustment are improperly adjusted;

3. Some noises can still predict that the engine will be damaged accidentally, so when the engine has a sound, it should be repaired immediately to avoid the expansion of the fault problem.

Timely cleaning and maintenance of relevant components.

On the issue of abnormal noise of automobiles, it is difficult for ordinary car owners to distinguish which ones are abnormal noises and which ones are reasonable abnormal noises. Only nearly 20% of the vehicles that went to the repair shop to detect abnormal noises really had problems. Models equipped with turbocharged engines are different; Models with engine guards may also make noises due to friction; After some car owners come into contact with different cars, it is likely that due to their lack of understanding of mechanical knowledge, they mistake the reasonable collision noise for a vehicle failure.

Therefore, learn to distinguish the abnormal noise of the car and avoid wasting time and energy.

Second, the identification method of car noise:

In practice, due to the limitations of working conditions, it is difficult to measure the sound of the car with special instruments, and the sound of the car can only be described and compared with the judgment of the sound in daily life. For example, the "rattle" sound caused by the dry friction of the bearing, and the "click" sound similar to the small hammer hitting the cement floor caused by the excessive valve clearance.

1. Correctly distinguish between normal and abnormal sounds.

The vibration of each mechanism in the work of the car will emit a variety of sounds, but the sound does not mean that the car is faulty, in order to avoid unnecessary disassembly, we must first distinguish between normal sound and abnormal noise. The normal vibration sound of each system component (such as the noise on the surface of the engine), the impact sound of the gear when shifting, the air intake sound and exhaust sound of using gas as the working source, and the gear meshing noise are all normal sounds. Abnormal noise (abnormal noise) can be divided into slight noise, general noise and malignant noise according to the impact on the performance of the car.

Slight noise, such as the flashover sound of high-voltage electric leakage, the slight loose sound of rolling bearings, etc., the general volume is small, the degree of wear of the parts is not large, and there is no significant change for a long time, and this kind of fault can still maintain the normal operation of the car without repair.

3. When diagnosing abnormal noise, attention should be paid to creating good auscultation conditions and trying to eliminate the interference of other noises, so as not to affect the accuracy of judgment.

It is best to consciously amplify or reduce the sound, that is, use a screw or other metal rod as a stestological instrument to contact the sound part to amplify the sound, or use a single cylinder fire cut-off to reduce the sound to meet the diagnostic needs. The auscultation site should be kept quiet to minimize human interference.
