After how much mileage to change the air filter. Air filter - for what is needed and how often change. What kind of varieties are

Why important timely replacement air filter?

• Car owners who do not consider the replacement of the air filter with paramount task, usually motivate this by the fact that they do not feel the difference between "to" and "after". And since there is no difference, then the role of this simple detail is not so important. Is it really? And how much do it unreasonable replacement Filtering element? The design of the air filter is simple. It may externally differ depending on the brand and model Row Car, but always has a similar shape of the inner structure. These are filtering elements from impregnated synthetic tissue or cardboard, plates embedded in a plastic case.

Replace air filter It is usually not difficult. It is only necessary to monitor that the filter body is tightly "sat down" into the landing socket, and rather fragile attachments fully snapped. If it happens that the air filter will be installed incorrectly, it will lead to its incomplete operation and reduce the characteristics of the car.

The engine air filter performs two important tasks:

Provides free air passage;

Prevents ingestion in the power unit of dirt, road dust, fluff, etc.

• If the filter is not changed on time, it will stop fully fulfilled both functions. The thin line between high-quality filtration and the unhindered passage of air into the combustion chamber is erased. The filter clogged and dirt can no longer provide a sufficient amount of oxygen for consumption by a power unit. It entails an increased fuel consumption, as well as reduced engine power.
• On the other hand, from the side of the filtration, the old air filter, installed under the hood, can not only reduce the indicators, but also to harm the car. Especially, it concerns cardboard filters. In the conditions of frosty winters or with sharp differences in the temperature mode, the filter that has long been worth throwing out, can be folded. In this case, the particles of the solar material get inside power aggregate and act as Abrasive, gradually cutting the life of the motor and approaching overhaul. It is worth saying that an aggressive mechanical action on the internal elements of the engine shows and ordinary road dust, which the scored filter cannot be fully filtered, and it enters the combustion chamber.

What time do you need to change the air filter?

To answer this question, it is worth considering an annual mileage that will be individual for each car. Leading manufacturers recommend to make a replacement of the air filter every 10,000 kilometers or once a year, timing this procedure for passing.

Welcome!
A lot of people after buying their first car begin to constantly ask questions, this kind: "How does it work?" "Why does this thing need this thing here?" etc. Today we will try specifically for such people, that is, for you, to reveal the whole essence "For what the air filter is needed for the car!" And we will try to make it easier as possible so that later you no longer have any questions in the future.

Note!
If all the same you will have something not clear, then, in this case, ask your questions in the comments and we will gladly answer them!

Summary:

Why do you need an air filter?

The air filter helps to clean the air that falls into the cylinders from dust, from exhaust gases Which are in the air, as well as from other small particles that can adversely affect the operation of the engine.

It also contributes to a slight increase in power, as well as a minor decrease. fuel consumptionbut this is all connected only with the fact that thanks to the filter in the engine does not fall dust and traffic fumes Because of which the car engine loses its power and eventually destroys.

So that you have more than the importance of the air filter in the system, will answer one often asked the question: "What would happen if the car was operated with a highly contaminated air filter?". And the answer is: "The car will go much worse, especially if the filter is very polluted. And this will also adversely affect the consumption of fuel at the car, and therefore it will increase. "

And most importantly, with a strongly polluted filter dust that falls out of the air to the cylinders will be very much erased by the mirror of these cylinders, and therefore the motor resource can very much.

When should I change the air filter?

The air filter needs to be changed depending on the terrain in which you are. For example, in order for you more clearly, we will take two cities: "Moscow" and "Ulyanovsk".

At the moment, Ulyanovsk is considered not so contaminated by the city, unlike Moscow, it affects a lot of factors since various plants and ending with the population of the country.

Not only a person for breathing is needed clean air, the same need is the engine of the car. Yes, do not be surprised! It has been proven that for the combustion of one kilogram of gasoline requires about 15 kilograms of air, while the air must be clean, without impurities of dust, otherwise not to avoid the accelerated wear of the piston engine group, as well as bearings and crankshaft. You probably wonder: "With what to clean the air entering the engine?". We answer: "The air filter is successfully coped with this task."

Currently, air filters are based on the material used as a filtering element, in form, by the method and degree of filtering, but the principle of action of all air filters The same air enters the housing through the air, in which the filter element is located. When passing through the last dust particles, delayed, and the purified air falls into the intake manifold of the engine.

We are confident, having acquainted with the principle of operation of the air filter, you, dear visitors to our portal, have no doubt that it needs a periodic replacement. However, this is the question: "How often to change the air filter?".

Only professionals, those who are well familiar with the principle of action of the air filter, as well as those who know do not appear, can give an exhaustive response to this question. Each manufacturer in the operating instructions indicates the recommended air filter replacement period. However, it will be fair to recognize that a certain number, through how much an air filter should be changed, simply does not exist. So the interval of replacement of this part depends primarily on the operating conditions of the car. It is believed that in a gentle mode, when traveling on unwanted and unscrupulous roads, the air filter does not lose its properties even after running 15,000 - 20,000 kilometers. However, if you are accustomed to conquer the country roads on your iron horse or, on the contrary, it is quite often you for hours are idle in traffic jams, it will not be superfluous through every 8,000 - 10,000 mileage kilometers. If we neglect the recommendations, you risk to face unpleasant surprises, which can be presented to the scored filter, and this is:
Increasing fuel consumption
An increase in carbon dioxide in the exhaust gases,
Raising operating temperature engine,
Motor power loss.

Unfortunately, listed is not the worst. The saddest consequence of driving with a clogged air filter is the failure of the engine, we think everyone understands what expenses it threatens, and that the replacement of the air filter is not just a whim.

Love your car, spend timely maintenance And then your Iron horse will be faithful to serve you for a long time, please the unpretentiousness in operation and will not let us down in the most dangerous situation. Good luck on the roads!

To form the fuel-air mixture to the combustion chamber, clean air should flow. The conditions in which cars are operated are far from ideal. Dust, dirt, combustion elements, midges and many other garbage, which will go to the combustion chamber, will score fuel system and otherwise hurt the engine, if no cleaner passes. To avoid similar problems, an air filter is used. The air is sucked through it, and dirt settles on the filter, which periodically should be changed.

How often to change the air filter

Replacing the air filter is not the most difficult procedure that the driver can perform independently. This consuming item is inexpensive, and its installation will not take more than 10 minutes. After changing the air filter in a timely manner, you can avoid the occurrence of the engine problems, the elimination of which will cost much more expensive.

How often to change the air filter is indicated in the literature on the operation of a specific car model. If the manufacturer does not specify such information, the air filter replacement rule should be followed simultaneously with the oil change, that is, every 10,000-15000 kilometers. At the same time, there is one important exception: when operating the car outside urban conditions, that is, in rural areas, it is necessary to replace the air filter more often, because due to the abundance of dust on the ground roads it is faster.

Air filter pollution symptoms

Drivers who are used to serving a car on the service should know the symptoms in which they need to independently replace the air filter. A small expenditure item can lead not only to the problems with the engine, if the garbage starts to get into it, but in general will affect the car. Here are just some symptoms that arise if the air filter is dirty:

If you continue to operate a car with a contaminated air filter, a few thousand kilometers have problems with ignition candles, electronics, over time the "Check engine" light will turn around.

How to clean the air filter

Despite the low cost of the filtering element, the drivers may have a desire to save on it, extinguishing its service life. The air filter itself consists of a plastic housing and a filtering element, which is a paper with large pores used to pass air. At these pores, dirt is clogged, and it is it prevents further passage of air.

Wonder how to clean the air filter is not even worth it. The fact is that without damage to the paper element, the dirt will not succeed. Accordingly, it will be possible to remove only large trash particles, stuck between the filter elements. A fundamentally in situations will not be affected, and the problems associated with air filter contamination will not leave anywhere.

How to change the air filter

Air filter replacement - simple procedurewhich will not take more than 10 minutes if there are all required tools. To prepare for replacing the filter, you will need:

In any car today, several types of filters are used at the same time. Each of them has its own tasks, but most often car enthusiasts face air.

This question is asked by many novice motorists.

The main task of the air filter is the protection of the engine from dirt and dust, which come outside, settled on the engine. Another important feature is to provide the necessary air flow into the steel heart of the machine.

Also, this device absorbs the noise level and helps adjust the temperature of the combustible mixture.

Gradually, the filtering element is clogged, which leads to a decrease in the amount of air entered into the engine, the engine begins to work worse, it is possible to twisting the car during acceleration, fuel consumption is growing.

Thus, the timely replacement of this consumable material is necessary to provide uninterrupted and clear work of the heart of the car - its engine.

What are the types of air filters in the car

It is important to note that the variety of filters presented in the market is explained by the variety of cars.

They differ:

1. Sizes
2. Form
3. Filtering method
4. Filtration degree (single-stage and multistage)

For passenger cars Compact devices with limited working surface are used. BUT air filter sizes for cars special purpose, buses, trucks, respectively, larger, as they have to clean large air volumes.

The form allocate round and rectangular models. The first in all indicators lose, they cope with cleaning, they are less practical and considered outdated models.

It is worth noting the differences in car air filter housings. Cabinet filters, that is, having a shell to install the material, are not often found, usually the air intakes have a plastic casing in which the open filter is installed.

We will analyze in more detail:

1. Inertial.
   At the moment, it is rarely used, since they were supplied to more modern counterparts. Externally is a volumetric case with a pillow from the Kapron fishing line. Primary cleaning is performed due to dust settling, secondary - due to the pillow. The efficiency of the device is low, it must be regularly rinsed.
2. Inertia-butter.
   They are considered outdated, but still used in agricultural machinery. From inertials are distinguished by the presence at the bottom of the housing motor oilwhich partially catches dust and dirt. It needs periodic flushing and replacing oil.
3. Paper.
   Used B. modern cars. Air is cleaned due to passing through porous paper, folded in a certain way. Such devices produce purification not only by the outer surface, but also internal content. Interlaced paper fibers capture particles up to 1 micron particles. After contamination is simply replaced with new ones.

Most often, cardboard is used for the manufacture of paper filters, but some manufacturers, for example, in Japan, use synthetic materials that require more attentive observance of the replacement intervals.

Paper filters are represented by three species:

1. Panel
2. Ring
3. Cylindrical.

Ring and panel can have a frame and frameless design, cylindrical - always with frame.

An annular-type device has a round shape, models with a frame design use a frame of an aluminum mesh. Face parts are reinforced with foam rubber to prevent contaminated air from entering the slot between the case and the filter. Porous paper is laid in the form of a harmonica. Such models are installed on vehicles with a carburetor.

Cylindrical filters are used for trucks that are similar to the annular structure, but have a large filter element.

Injector cars are equipped with panel models. Consist of a layer of foam rubber, a frame of a grid and a folded harmonic paper.

To the question what is affected by the air filter in the carSpecialists answer - on the durability of the engine. The better the air filter is used in the car, reliable engine Protected from contaminants from the outside.

IN sports cars Use five-layer gauze impregnated with oil. Such consumables They differ in less resistance and can be applied repeatedly.

4. Filters with zero resistance.

A foam or cotton fabric is used as a filter material. Due to the processing special compositions It is possible to reduce the resistance of the air flow. This material can be used repeatedly, requires washing with special shampoos and re-impregnation.

Replacing the air filter of the car - when it is worth thinking about it

Materials are recommended every 15,000 - 20,000 kilometers. But this figure may vary depending on the intensity of the use of the car and the level of air pollution. Thus, residents of large cities and cities with industrial enterprises must change filters more often than residents of small settlements.

On the other hand, those who live in the villages without roads with solid coverage are also forced to not forget about the regular replacement.

But even if the car is rarely driving, twice a year - before the start of the winter and summer season, take care of the replacement yet. Otherwise, not to avoid the following problems:

1. Enhance fuel consumption by 10-15%,
2. Engine disorders with high risk of its further failure.

Evaluate the need to replace or air filter cleaning car You can face at any time. To do this, you need to open the hood, deduct metal clashes and remove the filter. If in it a lot of stuck sauards, then it's time to throw it out and put a new one.

Many motorists perform a replacement with their own hands, as it is simple enough. If the car is under warranty, specialists perform the replacement of filters during regular maintenance.

How to clean the air filter of the car - is it possible to wash it

Cardboard in paper models is not intended for flushing. It can also be impregnated with liquids or oils, as they reduce resistance. But this does not apply to industrial models made in industrial conditions.

It is impossible to resort to blowing, since small particles in the pores of the filter can lead to premature wear Engine.

However, if you decide to save and clean the device, remove it from the machine and manually remove large contaminants. Next, neatly vacuum cleaner collect fine dust. Make sure the device remains as integer, and put it in place. However, it is worth keeping in mind that the worn material can be broken at any time, and then it will have to spend much more on its repair than to buy a new filter element.
