Filter "Nulevik": pros and cons. Pros and disadvantages of zero resistance filter Why need a zero resistance filter by car

The desire to increase the power and the dynamics of their car is almost all car enthusiasts. At the same time, each uses its methods based on the possibilities and level of knowledge.

Some - optimize the motor, others - set various bodies and spoilers, others use high-quality "consumables" and so on.

But experienced auto owners know about another popular method - installation of the zero resistance filter.

So what is this device? What are the differences of "zulevik" from standard filters? Does it make sense to spend money? Let's figure it out.

Why do you need a zero resistance filter and where is it applied?

The task of the air filter installed in each car is to clean the streams entering the engine from various "garbage". But here "stick" in two ends.

On the one hand, installing the filter allows you to clean the air, and on the other, it creates an additional stream resistance.

The result is a reduction in power, which is especially noticeable as the filter element contaminates.

The zero resistance filter is an alternative to the classic filter. The main purpose is to reduce the overall resistance of the air without deteriorating the quality of cleaning.

It is believed that the installation of such a filter allows you to achieve an increase in the power of the motor on average by 5-7%. At the same time, it is almost no possibility to feel the difference from the installation. Only the facts that you have to believe are left.

"Zuleviki" are actively used on sports cars everything for the same purpose - add power to the power node. In this case, any alternatives are not even considered.

But it is worth considering that the difference between sports machines not only in the installation of a special filter, but also in a more advanced system of output, allowing to produce large volumes of exhaust gases even with maximum revolutions.

What is the difference from other types of filters?

The main difference between "zulevik" lies in its design. Classic filters installed on most of the car are made of paper (more precisely, from compressed fibers).

The stream of air masses passes through small holes in the fibers, and then goes to the motor.

As soon as the fibers are clogged, the resistance rises and increases, because the air needs to look for new ways to overcome the obstacles. If you do nothing, then the power of the motor falls.

Taking into account the existing standards, the paper filter should have a greater thickness at maximum fiber scope. With such a design, high-quality cleaning is ensured, but the resistance is overestimated immediately after installation.

The design of "zulevik" is based on the principle of resistance to resistance.

The device is based on several cotton layers, which effectively delays dust and dirt. At the same time detained particles, in fact, become part of the product.

Due to this, the effectiveness of the filter element is higher and one square centimeter of the surface takes more dust than the predecessor.

Cotton cloth is clamped in an aluminum screen, which increases the filter surface. The developers assure that the "zulevik" working part is 4-5 times more than in a classic filter, which ensures a long service life and less product resistance.

This is achieved thanks to another factor - the presence of a special coating (oil) on cotton, which delays dirt without harm to flow.

The principle of filter operation, its features

The principle of the "Nulevik" action is based on two factors:

• high-quality cleaning of the flow entering the motor;
• minimum air resistance.

The effectiveness of the zero resistance filter is explained by the unique design and the use of cotton (and not paper) material.

The incoming stream is filtered from dust without much contamination for the product. Due to the special impregnation, the particles entering the filter are settled on the surface and do not interfere with the flow of air to the combustion chamber.

As a result, an adequate amount of air falls into the intake collector, and the power of the power node is growing.

The advantages and disadvantages of "zulevikov"

As practice shows, such filters have their own positive and negative qualities.

Let's start with the advantages:

• power increase by 5-7%. Of course, for the driver it can be unnoticed, but when installing in a complex with other types, the result can be fought on yourself;
• change the sound characteristics of the motor. It is believed that the filter element makes a special sound, which changes the overall hum from the boost space. Many car enthusiasts establish "zuleviki" for this reason;
• the appearance of space is changing under the hood - it acquires greater sportiness.

Cons "Nulevik":

• the need for permanent care than not all car owners love to do;
• available for the price filters are low quality, so they are almost immediately clogged. The oil is faster and oil, which leads to a decrease in the resource of the power node.

How to care for such filters?

As already mentioned, one of the main flaws of the filter is the need for regular care.

After buying and installing the product, it is necessary to rinse regularly and process. At the same time, the processing on the principle "removed-washed-installed" will no longer be passed - there is a special algorithm.

Waskening frequency - every 5-6 thousand kilometers. If the car is operated in the area with an increased dust or off-road, then it is necessary to clean the filter more often.

If you forget about the maintenance of the device, then the machine becomes "voracious" and "stupid".

The algorithm of action looks like this:

To care for "zuleviki" there are even special kits, which contains flushing and impregnation. Several manipulations that are described above and the product looks like new.

Note that the amount of flushing may be limited and is about 20 pieces. After that, it is worth installing a new filter.

Installation features

Many motorists allow a big mistake - they incorrectly install "nulevik" because of which it is not capable of performing its functions normally.

For example, the filter is installed too close to the hot motor or the release collector. Here it is time to remember physics.

Cold air density is higher than hot. As a result, "shove" into the combustion chamber is easier cold air than hot.

Consequently, the "nulevik" should be located as far as possible from any sources of heat (motor, manufacturer of release and other).

In addition, the contaminated filter will have to "repair", which will also take some time.

Today there is a mass of zero filter models that are designed for mounting on various types of cars - with an injector or carburetor.

Mesh, foam rubber or cotton can be used as a material. The highest degree of cleaning from the filters from the foam rubber, but they have more resistance than "fellow".

Installation of "Nulevik" on different cars is made in different ways, but in general it is necessary to follow the following algorithm:

• discard the DMRV connector (fuel consumption sensor);
• use a screwdriver to disconnect the rubber tube from DMRV;
• sensor fasteners remove from the housing (for this you have to unscrew a pair of bolts);
• remove the housing and remove the rubber locks (use cliffs or pliers);
• unscrew the mount from the wire group;
• fold a couple of bolts from the DMRV retainer to the zulevik fastener;
• put a new filter on DMRV, stretch the clamping clamp and plug the sensor.

That's all, the new filter is installed on the car.

How to make a zero filter with your own hands?

Some car enthusiasts in the desire to save are decided to make a "nulevik" with their own hands.

The source is used by the factory round filter, which was mounted at one time on the Moskvich brand cars.

To make a "nulevik" you can use different ways. One of them we describe below.

Pregnant tools (foam rubber, sealant, sharp knife, glue and other). The total price of the question is not more than 3-4 US dollars.

Immediately it is worth noting that the redesigned "nulevik" is unlikely to add the power to your car. The reason is in obsolete technologies that were used in the production of cars in the 70-80s.

Manufacturers when creating filters have little thought about the importance of cleaning, so the old products detain only very large pieces of dirt. So, "creating" a zero filter, you go to a certain risk and you can "kill" your engine.

By the way, the only car where such a zero filter will have to "go to the yard" is "Moskvich". At the same time there are owners who immediately cut the walls to eliminate the excessive stream resistance.

If you still decided to experiment, then the sequence will be as follows:

• remove the standard device;
• from a piece of plywood make a rectangular shape adapter with a hole.

Experience four more holes and fix the adapter to the air meter sensor.

Before this, set a piece of pipe into the hole and process the gap sealant;

• in two circles from plywood, do additional holes. In this case, on the outer circle, make a hole of the larger diameter, and on the inner (installed near the air unit) - by the diameter of the installed pipe. The latter is seated with the help of sealant;
• make 3 bars with a length of about 16-18 centimeters and use them to fasten the circles. As a result, it turns out a peculiar figure of the cylindrical form. Since there are no plywoods in Brus, then on the edges it is necessary to make holes for mounting the screws (otherwise plywood may be damaged);
• to eliminate the porpolation of the foam rubber, make the housing. For its manufacture, you can take the grid for the joints of the GWL. Advantage - the presence of a sticky basis, which will allow you to immediately make a fixation;
• after from the outside, the foam rubber is pasted using thermhermotics, which allows you to securely and quickly fix the device;
• fix with sealant a couple of pieces of foam rubber for the side of the barrel;
• wear a foam rubber and fasten the bars from plywood using screeds.

There are simple solutions.

Engine tuning is an expensive pleasure that not every driver can afford. But there are inexpensive options, how to increase engine power. For example, install null resistance filter. It is believed that the filter nulevik allows you to improve the driving quality of the car, and it is not very expensive. As part of this article, we consider what pros and cons getting the driver from setting the zero resistance filter.

What is a zero resistance filter

The atmospheric air acts as a working fluid for modern internal combustion engines. Depending on the amount of air in the cylinders, the combustion of fuel varies. The more air - the greater the combustion. Accordingly, the more combustion, the greater the pressure during the piston working stroke, and the power of the engine and the temperature.

But with an increase in engine speed, the amount of air incoming becomes less due to the action of the resistance of the inlet path. To be clearer, you can do the following separation:

• With low revolutions, the filling depends on the throttle;
• With high speed when the throttle is open, the filling depends on other factors - the mechanical features of the intake system, the recovery settings and the air filter resistance.

Please note: - a mandatory element of any modern engine that cleans the air before entering the cylinders, which allows you to maintain the performance of the motor and avoid its premature breakdowns. However, even if the air filter is completely removed, it will not be possible to increase the speed of air intake, since the turbulence of the air intake pipe will cause losses when filling.

To reduce the resistance from the air filter of the air flow, uses a zero resistance filter. It is a certain compromise between the purification element and air bandwidth.

What is the zero resistance filter

The zero resistance filter can be made of cotton or foam rubber (with large pores). Mandatory torque in the filter is impregnation as a special oil, enveloping cells in the filter curtain. It provides basic filtration.

Please note: Filter filters are more durable.

The curtain itself in the zero resistance filter delays only a large dirt, having enough space for air passage. In this case, the oil impregnation performs the role of a filter of small particles. The air, passing through the "labyrinths" of the zero resistance filter, concerns the impregnation and moves on, and the microparticles of the dirt that are contained in it are settled on impregnation.

Unlike the usual air filter, the zero resistance filter needs regular maintenance. As can be understood from its principle of operation, while settling a large amount of garbage on an oily impregnation, the efficiency of the filter element is reduced, respectively, a filter washing and re-impregnation is required.

Pros and cons filter zero resistance

It is believed that setting the zero resistance filter helps to squeeze more power out of the engine. In fact, the increase is quite insignificant. If you test the car with zero resistance filters on a dynamometer stand, you can see that the use of it for power will only be when the gas pedal is intended to the floor, that is, the throttle is fully open. But for ordinary trips around the city, this advantage is insignificantly.

Please note: in this case we are talking about ordinary engines. A slightly more zero resistance filter gives an increase in power on forced engines, but only on those that are forced not by turbocharging, but turns. But there are nuances here, since in addition to the filter, it is necessary to install high-apparatus camshafts, adjust the receiver and intake valves.

And now about the minuses setting the zero resistance filter instead of an ordinary filter:

In addition, in some engines, the installation of the zero resistance sensor can lead to a decrease in maximum power due to the need to dismantle the regular air filter box. Without a box, the air will be transmitted heated, that is, less dense, which "strangles" the motor due to a decrease in the total mass of air.

Hello everyone! In turn, we have a fairly relevant and interesting topic. After all, we will talk about the nulevik filter. Many have heard about such an air filter, but not everyone knows exactly what it is for what is needed and what is it in him.

Nulevik put instead of air filter in a regular place. And it is important to understand what a similar device gives. Immediately make a reservation, then it has a plus and cons. But for objectivity I will try to talk in detail about the device first, and then summarize whether there is a benefit in this purchase, is it worth installing a nulevik for a car, on a moped, on some VAZ or on the carburetor, for example. After all, the network is very often the craftsmen who put a device for Pidburg and Alpha, that is, on a scooter.

Do not forget to share your opinion. Especially if you have personal experience in applying zero resistance filters. It is so correct to call zuleviki.

Why it is necessary

To begin with, we will understand what it is and with what it is eaten. A standard or ordinary air filter is designed to clean the air entering the engine, from all kinds of contaminants. It is by air filtering that the power loss occurs.

It is determined by the fact that the cleansing elements in the filter design (usually special paper) create resistance to air flow. It is not surprising because the filtration material is very dense. And the greater the resistance indicators, the greater the total power is lost. As you know, the increase in power is achieved by increasing the amount of incoming air. It is here that the scene comes out a zero resistance filter.

Nulevik is an alternative for a standard cleaner. Its design is such that the device reduces resistance to the inlet, while not sacrificing the air purification itself. Thus, the increase in power is achieved.

And then there is a natural question about whether your prior is worthy, VAZ 2112 or VAZ 2114 of this element? Is it worth buying a nulevik at all, wanting to slightly increase the engine power?

Practice and research show that such a small tuning as a zero setting allows you to get an increase in 3-5% of power. If it is a low-power car, then you definitely do not feel the increase in several horsepower. Also, you will not see any difference in dynamics. But the numbers will be higher than you can comfort yourself.

Key advantages

Reading reviews on zuleviki, I met a lot of contradictory opinions. One put himself such a filter on the injector, and remained very satisfied. Another spent a bunch of money on a nulevik from K & N and its installation, wanted changes, and in the end I received only in vain the time spent. And such examples mass.

I will say right away that you do not have a problem from auto shops from auto shops. The price of some models is quite adequate, therefore it is not difficult to buy and relatively inexpensive. But whether such an element needs to install on Vaz with their own hands, the question is extremely interesting.

Let's start with good. Like any device, the nulevik has its pros and cons. By minuses include the cost in comparison with the usual air filter and the need for permanent cleaning.

As for the advantages, there are several of them.

• Increases power. Nulevic has a complex design that allows reducing resistance. This gives an increase in the number of horsepower;
• Simultaneous cleaning efficiency. Although the resistance drops, this does not affect the quality of air purification;
• Replacement frequency. Change nulevik as often as an ordinary filter, no need. For them, the possibility of washing. This allows you to return the operational characteristics to the full;
• Posterness in characteristics. Let a little, but nulevik adds power and increases torque;
• Sound. For many, it is important not power, but a sound characteristic of powerful motors. Nulevik creates such an effect, and in the end the car sounds very interesting.

To achieve the desired one, you will have to remove the standard filter, and in its place to establish the device of zero resistance. What is better to buy and install with your own hands, or give the car to the masters, decide for yourself. In the second case there will be a quality assurance and a competently selected filter. The main thing is that the specialists themselves are qualified and reliable.

And clear something

There is a common misconception, according to which, after removing the filter and the case, it is possible to significantly increase the engine power. This is absolutely not true.

It is important here to take into account that when developing the engine is made a thin calculation of the phases of gas distribution, in which the errors and losses on the filter are taken into account. And if dust starts into the engine, it will not be able to work for a long time. Here it is necessary to have a fence that will prevent the penetration of pollution. It is possible to reduce resistance by expanding the passing holes. But then the filtering quality will decrease.

Before looking for the article and buy a nulevik on your motorcycle or car, remember one simple truth. For cars without a powerful sports engine, the cost of buying such a filter will be absolutely meaningless. You will only spend in vain several thousand rubles. The only thing you get is a bit modified motor sound.

Zuleviki is suitable only for sports cars and cars with powerful power plants. It is allowed to use such a filter on serial motors only in cases where a comprehensive refinement is carried out. That is, a boring is made in the cylinders, an increased throttle is mounted, sports camshafts, etc. are installed. Here you can also put nulex in the kit.

Question of service

If you still decided to install a nulevik instead of a standard type air filter, then it will have to further care. The essence of care lies in cleaning and periodic impregnation with solutions. Moreover, a certain technology is strictly observed.

If this is not done, fuel consumption will significantly increase on the car, the power will fall and the car will begin to respond poorly to the increase in speed when the gas pedal is pressed.

You need:

• remove the filter;
• soft brushing Clear Pollution;
• remove dirt from the landing socket;
• rinse with water filter;
• shake several times, and not dry;
• apply a cleaning agent on both sides;
• install in place.

If the machine is operated in sufficient hard conditions, then such prevention is carried out at least every 8 thousand mileage kilometers. For normal conditions, 10-12 thousand km is enough. One nulevik can be flushed to 20 times. Then mandatory replacement.

What can be said about such zero resistance filters? In the photo they look spectacularly, they are expensive and in theory have important advantages over standard filters. But in relation to serial machines they are useless. It is a fact.

Nuleviki is relevant to put on powerful sports type engines and motors that are subject to serious technical tuning. By itself, the weather filter will not do on motors, the power of which does not exceed 120-150 horsepower.

The purity of the air supplied directly affects its resource and power. Therefore, the intake systems are supplied with filter elements. At the factories, the overwhelming majority of mass models of cars are supplied with paper filters, which due to the small size of the pores in the material reduce the air flow rate, which negatively affects the efficiency of the filter operation.

There is an alternative - zero resistance or zero filters. First of all, they differ from the standard paper, a much larger pore size, which do not particularly affect the flow rate and the presence of impregnation. Contaminating particles leave the air flow when it is bent in the labyrinth of the zulevic structure and, due to the impregnation, they stick to the walls of his pores.

According to the manufacturers of manufacturers, the above features of the operation of zero should increase engine power. And they, depending on the good faith of manufacturers, type of engine and a number of other factors, even cope with this task.

What does the zero resistance filter look like or nulevik.

From a constructive point of view, there are two types of zero resistance filters. The first is mounted in a regular place in the inlet box, the second - immediately before the throttle with the dismantling of the entire previous path. Both types are several layers of textile material impregnated with a special composition, which is called butter. Textile material has a more porous structure in comparison with paper, and the oil holds particles of pollution in its thicker.

Depending on the quality of the materials used varies and the cost of the part. In this case, the cone-shaped filters mounted before the throttle is usually more expensive than flat, installed in the regular place of paper filters.

One of the features of zero resistance filters is the need for regular maintenance. In order for a clogged filter in the process of long-term operation, the engine does not harm the engine, every 3-5 thousand kilometers of the mileage is recommended to rinse it and update the impregnation. Specialized stores offer a wide range of flushing and impregnation compositions. On the other hand, it is easier to replace the paper filter once every 10 thousand km than every two wash and re-impregnate the nulevik.

It should be noted that the continuous use of impregnation filters with MAF or MAP sensors installed immediately after the filter is fraught with a serious engine breakage. The intensive flow of air blows the oil that settles on the sensor and distorts its testimony.

What gives a zero resistance filter

Installing the zero resistance filter, depending on the type of engine and its initial power, issues various results:

1. On turbocharged engines of noticeable power output is not detected.
2. Atmospheric power units of low power show an increase from 2% to 5%.
3. With a successful coincidence of the circumstances and the use of high-quality filters, the increase can be 7%, but this growth will be episodic.

Thus, no tangible growth of horsepower is observed, because the driver feels the difference more than 10%. Therefore, installing a reduced resistance filter is or hunting for numbers, or not the most essential part of the complex tuning. In fact, a greater increase in power can be obtained simply by reducing the weight of the car.

Pros and cons filter zero resistance

Nulevik under the hood.

Naturally installing the filter of zero resistance - not quite meaningless business. Especially if you do not pay attention to power parameters. Like any other technological solution, it has strengths and weaknesses.

Advantages of nulevikov

• Be that as it may, they increase the power of the engines. Especially small atmospheric. Yes, the increase is minimal, but it is.
• Filtration with a smaller reduction of air flow speed optimizes fuel consumption.
• There are models for installation in regular seats without modifications.
• The cone-shaped models allow you to dismantle the intake path up to the throttle, which frees the place under the hood, say, to install the overall turbine.
• The appearance of the characteristic sound of the engine with the zero. Although this is a purely decorative advantage that does not affect power.
• A longer service life due to the possibility of periodic service, and not replacement.

Disadvantages of zulevikov

• Significantly higher cost in comparison with regular paper filters. The cost of branded models reaches 150 dollars, while a typical bumba filter can be purchased for 200-300 rubles.
• The cone-shaped filters work with hot air from under the hood, which can negatively affect the motor status and other nodes.
• Non-permanent and dubious efficiency, which depends on a variety of factors, and sometimes absent.

Given the above information, you can equate the use of a zero filter to a piece of plastic, fixed above the knitting of the bike. Only instead of a bike car, and instead of plastic - a detail cost from 2000 rubles. After all, the essence of tuning, first of all, in increasing power, and not in decorative changes.

Some car owners, grief desire to increase the power of their car and improve the dynamics, put a zero resistance filter. As far as justified, the uninitiated person is difficult to judge. Among motorists there are direct opposite opinions about such modernization of the car. Some argue that the installation of a zero resistance filter significantly increases the engine power strangled by a regular air filter. Others are confident that one "zulevik" is not enough to improve the power characteristics, and therefore put it, no sense. In addition, there is a commander that such a device is much worse coping with air purification entering the engine.

The truth lies somewhere near, rather, in the middle of these two opposing opinions. We will tell you that, in fact, is a zero resistance filter, in which its shortcomings and advantages, compared with the usual filter, and also talk about its service.

Filter of zero resistance: what is it?

Air contains many mechanical particles and chemical compounds. First of all, dust that gets into the engine cylinders is able to bring it out of order. To prevent possible breakdowns, air must be cleaned. This requires an air filter that performs mechanical cleaning.

The engine power depends on the amount of air contained in the working mixture. The stronger the air is filtered, the smaller its quantity enters the engine, and the more power decreases. Standard paper filters have a very greater air resistance, as they are made of very dense material. As the pores are contaminated, the filter is clogged, and it, in general, ceases to skip something, at times raising the resistance of the air.

Its filter component has several layers of cotton fabric, impregnated with a special mixture and installed between the aluminum screen. It allows you to almost freely undergo an airflow into the engine. Dirt particles settled on filter fibers without reducing its bandwidth. The zero resistance filter is because it is called that it practically does not prevent air penetration on the inlet. Moreover, this property "zulevik" is not reflected on the quality of cleaning. For this reason, it is installed on sports cars.

Pluses of zero resistance filter

So, let's list the main advantages of the zero resistance filter:

• First, this is an increased power factor without reducing the quality of air purification. The filter has a more complex design that guarantees low resistance, but at the same time efficient filtering that protects the piston system from wear, and the system inlet of the interface.
• Secondly, it disappears the need to change the filter every 15 thousand km. The cleaning component is easily washed with a special fluid, after which it acquires its initial properties.
• Thirdly, the zero resistance filter makes a characteristic sound inherent in racing machines and several additional "horses". And with medium and low revs, torque appears.

It should be noted that in order to obtain a tangible increase in power characteristics and torque, it is necessary to remove the regular air filter housing assembly with the filter cartridge and set the air flow sensor or on the nozzle connected to it, the cone filter - the nulevik that is selected according to With the diameter of the landing socket.

Minuses of zero resistance filter

As the saying goes: "Not all car carnival." Unfortunately, the zero resistance filter has a number of shortcomings, which can overlap all the advantages of this product. List the main ones:

• The zero resistance filter requires regular maintenance.
• The cost of quality zero is several times higher than the price of the usual filter.
• The increased power of 5-6% when installing the zero resistance filter, the driver practically does not feel, since physically person cannot catch the difference in the capacity of less than 5 horsepower.

The feasibility of installing the zero resistance filter

Do not be mistaken about the fact that if you remove the filter with the case, then you will significantly increase the engine power. The situation is not at all and all sorts of measurement of this confirmation. The reason is that the developers are calculated in advance the phases of gas distribution, taking into account the loss of air filtering. In addition, it is not worth risking the state of the engine, as it fails on the untreated air it will fail.

An obstacle for garbage in the form of a air filter is simply necessary. You can provide minimal stream resistance only by expanding the passing holes, a little worsened filtering quality.

Summing up, we can say that if your car does not have a sports engine, then the cost of several thousand to the zero resistance filter is not an idea. Nevertheless, this is the privilege of racing machines, and on the usual motor just a beautiful thing under the hood.

Another conversation, if you decide to comprehensively modify the car engine with a turbo or installation of sports camshafts, boring cylinders. In this case, the nulevic will have to the place. Together with a zero resistance filter, you can purchase an enlarged throttle, which will increase the return from the intake system of the motor.

Service of zero resistance filter

Installing a zero resistance filter obliges a car owner regularly rinse it and soak a special fluid that also costs money. Moreover, processing should be carried out according to a certain technology, instead of a simple algorithm of action "removed-set". It is impossible to miss the moment of service filter, since such negligence threatens to increase fuel consumption and reduced the power of the car.

• At the first stage of servicing the zero resistance filter, it should be removed and, armed with a brush with a soft bristle, carefully clean the filter element from large contaminants.
• After that, on both sides of the filter, a special solution is applied and the waiting for 10 minutes to complete impregnation.
• Next, it must be rinsed in the pelvic with water, and then substitute for a weak pressure of flow water.
• Nulevik is not dried, just shake water from it.
• The dry filter should be carefully examined for light spots on it. If they are available, the impregnation with a special solution will have to repeat.
• At the last stage, we put the filter into place.

Conclusion

Now you know what a zero resistance filter is and can conclude about the feasibility of using it. To reinforce the knowledge gained, we advise you to see the following video:
