Air filter through how much change. How often the engine filter is changed: Rules and Recommendations. Air filter pollution symptoms

October 3, 2016.

The air filter in the machine should be changed at least than recommended by the manufacturer. it important elementSince the air passing through it, participates in the working mixture in the form of an oxidant. If the past air purification system is contaminated, it will entail an increased wear of the engine elements. Previously will be released piston group Engine and bearings crankshaft. This will be a consequence of the content of a large amount of dust in motor oil. Dust acts on lubricated parts as abrasive material.

Filter Replacement Frequency?

Foreign manufacturers usually provide recommendations, how often it is necessary to change the filtering air element - at least once to fifteen thousand kilometers. On domestic machines, the resource is less - up to 10,000 kilometers. However, the maintenance of the car and operating conditions also plays an important role. So, B. winterwhen dust on the roads is practically absent, replacement frequency air filter You can slightly reduce.

On the contrary, when operating mainly in a dusty environment, to extend the motor resource the filter will have to be changed more often. Indirect signs of the need for maintenance of the air purification system are:

• increased fuel consumption;
• reducing the power of the power unit;
• increased percentage of carbon dioxide in the exhaust;
• difficult engine launch.

If such signs appeared, do not tighten with the replacement of the air filter, otherwise, in a short time, its working element breaks, and you, if you do not pay attention to the deterioration in the work of the power unit, ultimately have to sort out the motor much earlier time.

The effect of filter materials on the deadlines for its replacement

In many respects, the resource of the air purification element depends on the composition of the filter material. In the classic version it is made of paper impregnated with specials. The composition, the most modern elements are made of synthetics. This increases the operation of the consumable material, and about when changing such filters, manufacturers give their recommendations.

Extend the "mileage" of the air purification element is possible only by the careful operation of the car in the non-dusty zone. Attempt to rinse the filter element or any other way to clean it will not lead to good result - The filter will remain disposable, having ceased to perform its entire function in the machine. Small particles from the surface of the element will go deep into the pores and increasing the resistance, and the quality of air purification worsens.

The need to change the air filter in the car can be traced visually, independently producing its inspection.

If there is a dirt or poplar fluff on the filter element, it should immediately change to a new one, not trying to rinse or blow.

Using a non-original filter

If you use a non-original air filter, then the question about how often this item needs to be changed, it is impossible to definitely answer. It is not subject to doubt just what to do this will have much more often laid 10-15 thousand km.

The fact is that manufacturers of non-original consumables for cars, seeking to reduce the cost of cheap products, use a single-layer filter element, reducing the number of corrugations on it. At the same time, the paper in it becomes two times less. Consequently, to say for sure, after how many kilometers a mileage should be changed. original filters It is impossible, but at least it should be done two times more often than usual.

Evaluating the need for replacement, consider the fact that when entering the engine, even one percent of the air into the bypass of the filter element, the resource of the cylinder-piston group is reduced at five or more times. Therefore, do not allow the operation of the vehicle with the air filter resource, even if it looks clean. Saving funds here can lead to the need to unscheduled motor repair.

The state of modern ambient It is impossible to be called perfect. Circle polluted air, full of dust, foreign solid microparticles, harmful substances and other natural "surprises". And in such conditions, drivers should ride on their cars.

What will happen if solid microscopic elements contained in the air get inside the motor? Of course, it can very soon fail. The position can save the air filter installation that protects the engine from different microscopic items in the air. But this item is a consumable, that is, it must be changed periodically.

Often, the frequency of air filter change manufacturers indicate in the user automotive instructions. But such information is only suitable for motorists living in ideal climatic conditions. Most of us live in conditions of moderate, or even increased environmental pollution. Therefore, the filter change must be made in 2 (in most cases), or even 3 times more often (for conditions with increased environmental pollution). Replacing the filter is a simple deal that any motorist can perform. Yes, and the cost of a new filter is less than the restoration of the damaged motor.

What is a air filter

The main task of this consumility is the protection of the motor from foreign microscopic bodies contained in the air. Appearance The filter is made in the form of a harmonica made of a special material, the main property of which is the ability to prevent the promotion of various solid microparticles. Each day, the number of such foreign objects increases, which is the result of a poor air flow intake inside the power unit. Around the harmonica provides for the placement of seals, the assignment of which is to block the air passage inside the engine bypassing the filter.

In general, ignoring the need to replace the filter or its late installation is fraught with an increase in the rate of wear of the engine parts and serious damage to the motor in the near future.

When replacing filters, it is necessary to take into account the design of the car. After all, it is not suitable for each car, say, the filter of another form. In addition, the filters differ in each other by means of air purification (filters of cyclone, inertial and oil, direct filtering). To use the cleaner in climatic conditions with a moderate degree of contamination, you can use a regular filter, with an increased degree of contamination - a heavy cleaner.

Most car enthusiasts when installing the filter prefer the analogues with. Such details are used when conducting sports competitions when cars must be moved along the high degree of dusting.

But, despite the good performance of filters with zero resistance when racing, the use of such devices on ordinary machines will not give the desired effect. They are expensive, and when they are installed, it is necessary to carry out additional expensive tuning works, otherwise the efficiency of the filter zero resistance It will be just equal to zero.

When you need to replace the filter

Any driver can ask a question: "What frequently need to change air filters?" Nobody will give an exact answer to this question. After all, each manufacturer of the replacement rate of this detail is different. In addition, it is necessary to take into account the degree of pollution of the environment of a particular region.

If some motorists prefer to replace the filter within a certain pattern, then when it is replaced after the passage of every 10,000 kilometers, it will definitely protect his car from the premature worn out of the engine elements. Also replacing the item must also be replaced when the following features are manifested:

• Increase fuel consumption in the car.
• Significant reduction in motor power.
• Increasing the amount of CO2 in the exhaust.

When identifying these signs, you must take instructions and find a description of the air filter replacement sequence.

How to change air filters

Getting Started with the replacement of the filter element, it is necessary to take into account the design features of the car. Each manufacturer creparates in its own way and has a cleaner.

In general, the filter replacement algorithm in cars of different brands and models is slightly different. First, the driver opens the hood, then the air filter finds, after that he studies its mount (in most cases it is attached to simple latches). After that, the cleaner is removed and its condition is evaluated.

Note that filters are disposable and reusable. Disposable cleaners are replaced immediately. Reusable can be cleaned by vacuum cleaner. True, this method of caring for the machine cannot be called efficient (the dirt accumulated on the cleaner is not completely deleted). But still after these manipulations, the cleaner some time can perform its functions. After that, the new (or purified) filter is fixed again.

What experts say

According to the experienced motorists, the shift of the air filter should be combined with the replacement procedure machine oil. It is performed after 10-15 thousand km of travel. Thus, the maintenance of the entire engine will be performed to ensure its long and reliable operation.

To quickly pass the procedure, you need to read the user instructions for understanding the building of the motor and obtain information about the design of the filter used. New air filters are purchased only with the brand of the machine. If there are new modern devices in the auto shop, you must consult with specialists for the suitability of the cleaner for a particular car.

Other features of air filter replacement

When replacing the air filter, it is necessary to determine whether the motor is new. In machines with new ones not used with an increased load, the engine replacement is carried out more often than the cleaner. The filter replacement is carried out in times when the lubricant is pouring.

In vehicles with diesel turbocharged motors, the conditions of use of the cleaner require its replacement for each oil replacement at the time of maintenance.

Conclusion

Experienced drivers are recommended not to save on a cleaner whose quality affects the work of the entire power unit. Otherwise, the need to restore it (fraught with large cash costs) very soon can "delight" the owner of the car.

Repair or purchase of a new engine is very expensive. So do not forget about the timely replacement of the air filter and regular service car. The cost of performing these procedures is much less than the work performed when the automotive motor failure.

Good day, dear colleagues. The key to the longevity of the motor of your car directly depends on what we will "feed it". Now many have thought that it will be about gasoline: what to fill, and so on. And here is not! Let me remind you that the engine consumes not only gasoline, but a working mixture consisting of air and fuel vapor. And the air in it is much more. Today we will talk about how often the air filter is changed.

It is impossible to neglect the replacement as the first look of the simple and unnecessary element. Among all filters that are on a car, this we pay all less time:

• We change the oil when changing the oil, that is, once every 7-15 thousand km (read more about periodicity). And even if the driver forget about the replacement, then at the service station, he will surely remind him about it and ask to buy not only an oil canister, but also on a new filter element.
• The cabin filter, that is, the one that takes care of air purity in the cabin. The need to replace the driver in the literal sense feels on himself. Characteristic features are:

1. Fast fading of glasses;
2. Reducing the efficiency of blowing (air supply through deflectors), since the contaminated filter has elevated resistance;
3. Unpleasant smell in the cabin.

And no one will tell about the need to replace "air", the engine of the car is silent and can not speak.

The working mixture, which is supplied to the cylinders, has one part of gasoline and about 20 parts of air. The average unit of 1.6 liter engine consumes it about 20 cubic meters per 100 kilometers of the mileage. And this air needs to be cleaned. If this is not done, then all solid particles (dust, dirt, sand), which are very much, will fall inside the power unit. And this phenomenon naturally will have a negative way to work at work, and in consequences on the resource of the engine.

The obstacle between road dust and engine subsoil is the air filter.

A clogged filter from a friend of the engine turns into its enemy. The resistance in the intake manifold increases, and this leads to a decrease in the amount of air supplied, and this leads to a decrease in the power of the power unit.
Back from the flow of air, the dust particles that already contained in the filter fall into the engine.

What are varieties?

Filtering elements of ordinary "civilian" cars, differ mainly only in shape:

Sure, geometrical dimensions And constructive features contribute to a decrease or increase in resistance in the intake path. But this contribution is so insignificant that we, without being the owners of sports cars and the Bolids of Formula 1, we just do not feel.

Basically, cardboard is used for the manufacture of the filter. On sports cars you can find elements made of several layers of gauze, with special impregnation, which have a slightly smaller resistance than cardboard. Also more than once you could hear the wording of the zero resistance filter, but about it.

Replacement frequency

And now we turn to the most interesting and important - periodicity of the replacement. In addition to the fact that the filter changes under the regulations, the need for its update can be identified visually. Dark color, a large amount of dirt solid particles in the folds of cardboard, the first sign of the need for replacement. Also dried by mud "Intersproof" can be revealed to reduce the dynamic characteristics of the car.

To find out the replacement interval on your car, as always, first of all, refer to the instruction manual for the car. And here there may be only two options for the development of events:

1. Change upon each maintenance, and usually it is 10-15 thousand km;
2. Change with each even maintenance. If then-1 must be carried out by 15 thousand mileage, then even then-2 by 30, and so on (TO-4, TO-6 ...).

Moreover, if the manual appears the interservice interval of 10,000 km., Most likely the filter must be changed on even then.

Based on this, we get the need to replace every 15 - 30 thousand kilometers (depends on concrete brand and auto models).

Air filter for most cars is not such an expensive element, so I personally change all the filters for each oil replacement.

W. diesel engines, To the purity of the air supplied more stringent requirements. But diesel engines and less interservice interval, so everything written above applies to the power aggregates working on heavy fuel.

Now we made clarity to the question of the frequency of replacement of this simple part. We will say goodbye to this, see you on the blog pages.

For education combustible mixturenecessary for engine operation, you need a combination of fuel and air. On average, the car absorbs it from the atmosphere about 15 liters per 1 liter of fuel. It enters the system through the air intake, the air filter nozzle, which is usually installed next to the radiator grille.

Quality leaves him to desire a lot of better. Street dust, dirt rushes along with air to the motor through the collector, threatening with serious clogging, the output of the power unit and subsequent expensive repairs.

The average amount of dust is calculated, which can penetrate the "engine" for the period between two then (15 thousand km) - 100-150 g. This will deliberately lead to a breakdown of the power unit.

Reliable protection against listed trouble is an air filter that cuts off this sera. The air filter corrugation installed after it passes the purified atmospheric stream suitable for operation.

Also, this device levels the noise of air supply through the channels and adjusts the temperature of the combustible mixture in gasoline DVS. The last factor is especially necessary in the cold time to heal fuel. This achieves the optimal effect of combustion of fuel, ecology is improved: through exhaust system It turns out significantly less than harmful substances.

Air filter location in the car

The question where the engine filter is located, will not put even a novice car enthusiast in a dead end. It is placed in a prominent place under the hood in the upper part of it. This option of installation protects it from moisture from entering road coat In rainy weather. The wetting of the filter element is fraught with the destruction of the product.

If the carburetor type motor, the device is placed in a metal or rigid plastic body directly near the air intake channel from above the carburetor.

Injector motors, the filter element is also located next to the power unit in the plastic casing.

The part is fixed inside the case that easily opens with the help of fasteners.

Types of air filters

All devices are separated from the form of execution, filtering materials, method of cleaning and classes.

• I class. It includes high-quality products that provide 100% filtering. They are used on sports cars, improved models after tuning.
• Class II. These filters are kept on their surface with more than 1 microns.
• III class. Have a rough filtering ability. The magnitude of the dust particles of dust exceeds 10 microns.

The following type of gradation - in appearance. Products are produced in a round, rectangular, square or other form, based on the design features of accommodation under the hood.

Air filters for cars are also separated by the type of cleaning.

1. Inertia and oil. The product that gradually loses its relevance due to the complexity of the service. In it, the air flow passes through the filter and butter container. As a result, the weed particles sticking to the oil remain on the filter element.
2. Cyclone type. It works on the basis of centrifugal force and inertial movement, after the action of which pollution is collected in the garbage receipt.
3. Directional option. Most effective. It has a smaller resistance to air absorption, which has a favorably affect the dynamic characteristics of the engine.

Constructive design of products may be one or multistage.

Also, air purification filter would be frameless, cylindrical or panel. Selection of model under its brand Car manufacturers are determined after numerous tests. different optionsdefined best model For your motor. This proves once again what attention is paid to this component.

Air filter materials

The modern industry has significantly expanded the range of materials used to filter air in the car. We list the main options.

1. Paper. The most popular a budget option. Is different affordable price and ease of operation. Dirt particles are held on its porous surface made in the form of corrugations. The material passes additional processing, which significantly increases the service life. Among the disadvantages, it can be noted that it does not tolerate interaction with moisture and is distinguished by a disposable principle of work: the clogged part is not subject to recovery.
2. Fabric x / b or foam. The material is pre-impregnated in a special solution, it is folded by the harmonica for the formation of a larger surface area and is installed on the frame. The rigidity ribs of the latter prevent the loss of the form of the element. Such a method allows to better clean the air from pollution: Sorrow settles not only from above, but also in the thickness of the product. If the filter is thoroughly rinsed, it can be used again.
3. Synthetic fibers. This type due to its strength, repeated use conquers authority from consumers, reassigns cardboard to the background.
4. Five-layer gauze material, soaked in oil and placed on a frame design. Used in a complex with high power engines, on sports cars.

The most effective result gives full replacement Details for new.

How often do you need to change the filter in the car?

The replacement of the air filter is carried out on the basis of the features of the operation of a particular car. Manufacturers do not always declare timing. It is recommended to change air filters with the frequency of oil change in the engine, i.e. after 15 thousand km of mileage.

The owners of the car with diesel and turbochard will have to do it more often. Constructive features Such a motor node requires paying more attention to this part.

Before changing the air filter, you need to be lazy to spend it visual inspection. Moreover, there is no particular difficulty in carrying out this operation. Even a beginner will be able to distinguish the normal state of the product from polluted. There should be no oil spots on its surface. In this case, the filter replacement is required.

Inspection is recommended to spend more often in the summer season, especially car enthusiasts, "chasing" on country roads: residents of countryside, summer houses, fishermen and travel lovers. It is in these conditions that dust formation is most intensively. All this dirt through the air intake rushes into the inlet channel to the motor, threatening with serious complications for its work. Therefore, it is necessary to strictly observe the purity of the filter under these conditions.

Air filter clogging symptoms

In addition to inspection, the owner may understand that the filter is not all right, as of the machine. Let's tell about these signs.

1. The engine is badly started, sometimes stalls while driving.
2. Increases fuel consumption.
3. The yield of toxic gases increases.
4. The engine loses power.
5. Information about the incorrect operation of the power unit appears on the instrument panel.

In these cases, it is necessary to replace the filter element immediately.

The consequences of the late replacement of the engine air filter

Consider all the negative consequences of using a clogged or damaged filter.

In case of damage to the element, the dust enters the engine, the combustion chamber. The wear time of the details increases, which leads to early repairs.

When the air filter is clogged, the air enters the chamber in a limited amount. As a result, the enriched mixture burns not completely, malicious exhaust gases through the muffler rushed into the atmosphere, making damage to human health and the environment.

The engine is unstable, fuel consumption increases.

Selection of air filter

It is necessary to remember the following: a high-quality product will be securely protected.

Its cost, even in the original performance, will be many times less than the engine repair. Cheap fakes, distinguished by a throw price, will not secure reliably force aggregate. It is necessary to choose products recommended by the manufacturer of companies.

The filter element is selected based on the design sizes of the site, where it must be installed. The product of smaller dimensions will open access with unfiltered airflow to penetrate the combustion chambers and will not give the necessary amount of air flow.

Of the two parts are the same in size, it is necessary to choose goods with a large operational resource from high-quality material. So it will be more reliable and more profitable to the owner itself.

Replacing the filter with your own hands

It is possible to replace it yourself, for this you will not need special skills. In the absence of confidence or tools, it is better to contact the car service where qualified masters will quickly provide this service.

Before removing the air filter, it is necessary to prepare the tools of labor and dry rags. It needs to close the input manifold during operation to eliminate the ingress of dirt, fastening elements.

Tell how to replace the air filter on one of our most popular cars with our compatriots - Renault Logan.

The principle of operation is identical with the replacement of this detail on other brands of cars. The filter element is located in a plastic case located in the center of the engine compartment.

1. Open four latches located in the neighbor lobby glass Parts of the lid.
2. Using a screwdriver, we unscrew five screws on its opposite side, closer to the radiator.
3. Remove the filter, we carry out its inspection, remove the dust from the housing.
4. We put a new product, close the lid.
5. We screw the fasteners, close the cheeks.

Perhaps there is no such car owner who would not wish to extend the life of your car, protect it from premature unexpected breakdowns. However, one thing wants, and the other, as they say, do. But if you are ready for everything, then knowledge on the question, how often to change the air filter in the car engine, you will be accurately useful.

What is an air filter and why do you need a car?

Air filter - cleaning element of the car. It is represented in the form of, as a rule, "accordion" consisting of a filter material reinforced along the edges of the seal. This filter material protects the engine from dust coming into it with air.

The described process is very important for high-quality engine operation, because the effective combustion of fuel is guaranteed by the supply of a sufficient amount of air, which is reduced with a "scored" air filter that creates certain obstacles to the flow of oxygen into the combustion chamber. This affects the car's capacity, and on.

So, how often do you need to change the air filter?

All requirements K. consumables The car and the frequency of their replacement is always prescribed in the instructions for its operation (as a rule, every 30-40 km run). However, there are a number of cases (including the purchase of a used car in use), when it is not always possible to own information about the previous replacement of the cleansing element, so the output in this case is one to determine the degree of contamination of the filter itself (visual method). This is now going.

Diagnostics of air filter car.

So, the air filter under the hood car is fairly easy. Its dark plastic housing is located in the upper (sometimes side of it) parts of the engine. Open it with a screwdriver or using metal clips provided for in most models.

on Renault Logan

on Hyundai Solaris.

Remove the filter from its housing. Usually do it is also easy, even if the removable cartridge is screwed to the screws with the screws, just unscrew them.

After driving the element of interest to you landing, appreciate the visually degree of its pollution. Due to the fact that many manufacturers prefer to paint air filters in bright colors, do not make much difficulty.

Next, look through the light filter, so you will define its condition. In the event that the device does not have strong contaminants, it will only be enough to blow it. But if pollution is significant, better replace the air filter to the new one. Just do not try to rinse it with water, because it will not solve the problem - the dirt is still very tight in the walls of the cleaner, even more difficult to pass the flow of air streams.

Especially here it is really better not to save, because timely replacement The filter will save you from extra spending, and your car from many unwanted breakdowns: failure (and its further replacement) flow meter, appearance of scratches and cracks on the walls of the sleeves and pistons of the camera internal combustion and other things.
