What spark plugs are put on. Multi-electrode spark plugs. Why are they needed. My logical review and small test (BERU, NGK, CHAMPION). Your attention the best of them

Many systems are used in the design of the engine. One of these is the ignition system. It consists of coils, armored wires and candles. The latter play an essential role in the process ICE operation... The engine resource depends on their quality and serviceability. Experts recommend replacing them every 30-40 thousand kilometers. What kind of candles are suitable for "Prior" and how to put them? Let's try to understand this issue.

Classification

The choice must be approached as responsibly as possible. It is worth deciding which type of candle is best for the car.

So, these elements have their own classification by:

• The number of electrodes: two- and multi-electrode. The first type consists of several elements. This is the side and center electrode. These are installed regularly on the "Prior". As for the second type, they have one central and three side electrodes. As noted by the reviews, these candles have a greater resource and are more reliable.
• The type of material. Candles are often equipped with copper electrodes. What are the best candles to choose for "Prior"? Judging by the reviews, they have a small resource - up to 30 thousand kilometers. But recently more "tenacious" iridium analogs have appeared on the market. Their resource is about 60 thousand. By the way, such candles have a slightly smaller diameter of the central electrode. If on copper it is 2.5 millimeters, then on iridium it is 0.7 millimeters.
• Thread diameter. When buying, check with the seller for which engine you need spark plugs. So, 16-valve valves are equipped with elements with a smaller head size and thread diameter. Candles from an 8-valve engine in a Prioru 16v simply will not work.
• Heat number. This parameter means the pressure at which the candle is easier to glow. There are cold and hot types. The glowing number of these candles is 20 or more for the first and 11-14 for the second. What candles are better for "Prioru" 16 cl.? There is no definite answer to this question. But there are also universal options. In this case, the glow number is from 11 to 20. It is these candles that many motorists take. They behave well both in summer and in frost.

Regularly, the Volzhsky Automobile Plant uses candles marked AU17DVRM.

Manufacturer - "APS Priority". Judging by the reviews, the resource of these candles is 25 thousand kilometers. This is quite good considering the low cost - 400 rubles per set. But products with this marking do not perform well in cold weather. What kind of candles to put on the Prioru 16 valves for winter operation? It is better to use "Priority A 15 DVRM" here. These candles have a lower glow number. They ignite more easily at low temperatures.

Analogs

What candles are better for "Prioru" 16 cl.? For those who do not want to buy factory candles, there is a huge selection of analogs:

• Products from the British manufacturer "Champion". What candles are better for "Prioru" 16 cl.? For such an engine it is worth purchasing the "Champion" RC9YC.
• Candles from German manufacturer"I take." They are not very popular, but they have a high resource. Marking for "Priora" - 14FR7DU.
• Japanese NGK candles... Perhaps the most popular analogue of factory products. For 16-valve "Priora" NGK marked BCPR6ES are ideal.
• Denso. This is also a Japanese manufacturer. The cost is on a par with NGK, the quality is also not inferior. For Priora, you should buy Denso Q20PR-U11.
• "Brisk" (Czech Republic). Another popular spark plug manufacturer. The manufacturer offers products with a different incandescence number and number of electrodes. For "Priora" candles DR15YC-1 are suitable. The same ones are used on the Kalina engines of the first and second generation, with a 16-valve timing mechanism. But judging by the reviews, the products are of low quality - the electrodes are strongly displaced from the center, which is unacceptable for such products.

What candles are better at the present time for a VAZ 16 cl.? When choosing, you should give preference to the original - AU17DVRM. By the way, there is an inscription “BOSH Group” on the packaging, but the products are made in Russia. For those who want to use an analogue, NGK candles are suitable. They are distinguished by a good resource and low cost.

How to replace? Cooking tools

So, we have decided which candles are better for "Prior" 16 cl. Now you need to prepare the replacement tools, namely:

• Spark plug wrench for "16" (preferably with a powerful handle).
• Slotted screwdriver.
• In the absence of a key, a socket candle head for "16" with an extension will do. It is desirable that it have a magnet or an elastic band at the end - this will make it easier to remove the candle from the well.

Getting Started

So, first, open the hood and remove the decorative engine cover.

Note! When pulling out the high-voltage wire, do not grasp the cord as it may be damaged. You only need to grab the rubber tip. Misfire may occur if the element is damaged. The engine will start to triple, and the car itself will consume a lot of fuel (since it needs more energy to push the idle piston in the cylinder).

Now let's move on to the candles themselves. We lower a specialized key into the mine and begin to unscrew the candle counterclockwise by means of the handle.

It must be taken out extremely carefully - it must not be allowed to fall into the well. Otherwise, part of the insulator may break off and fragments will fall into the cylinder.

Helpful advice: in the absence of a key with a magnet, you can use the ignition module itself - install it on the end of the spark plug and pull it back out. So we can get the old element neatly and without damage.

Install new

How are the candles replaced next? Before installing new ones, check the gap between the side and center electrodes. It should be about one millimeter. The parameter is checked with a round probe. It is shown in the photo below:

If the gap is in order, put the plug on the tip of the ignition module and lower it into the shaft. Next, use the key to twist it all the way. You don't need to pull too hard. The recommended tightening torque is 25 to 30 Nm. In the next step, we fasten the coils and insert the terminals.

We test the work

So, we start the car and listen to its work. The motor should not triple and shake. If so, check that the plugs are installed correctly. Motorists often confuse the position of the armored conduits. Because of this, the engine cannot start at all. To prevent this, each of the ignition modules is pre-signed.

If carbon deposits appear

After 15 thousand kilometers, it is recommended to re-examine the condition of the candles. Sometimes a brownish-yellow carbon deposit can be observed on the surface of the electrodes. This indicates the use of fuel with octane number not suitable for the vehicle. When the spark plugs overheat, soot will acquire White color... Erosion is not excluded. The reason may be an early ignition timing. Sometimes the candle is just loosely screwed on. Also, with early ignition, the electrode itself melts. Such a candle is only for replacement. Which candles are better for "Prior" class 16, see above.

If the car is troit, you should check the part with a tester for operability. Usually a gun with a metal tip and a cap is used for this. The tip is touched and the cap is put on the outlet for armored wires. When the trigger is pulled, a spark should go between the electrodes. If it is not there, the item is to be replaced.

Finally

So, we found out which candles are better for the "Prior" 16 cl. choose and how to replace them. During the work, it is advisable to check candle well for the presence of oil. If it is there, it may have burned out in the engine. cylinder head gasket... As for the question of choice, many are advised to take factory candles. They work no worse than their counterparts, and their cost is acceptable for buyers. Candles with a resistor have shown themselves well - breakdowns in them are reduced to zero.

According to technical regulations, spark plugs in engines 21116 and 21126 should be changed during TO-2, that is, after 30 thousand kilometers. In fact, this period can be extended one and a half times, if we are talking about a sparing operation. But you should not do this if the car is under warranty (then the replacement is made according to the regulations). Here we list which spark plugs are suitable for each of the specified engines. We will assume that the owner of Kalina-2 uses the catalogs of the following companies: BERU, CHAMPION, NGK, DENSO, BRISK, BOSCH.

• JSC ZAZS (Russia) - AU17DVRM, A17DVRM;
• BERU (Germany) - 14FR-7DU, 14R-7DU;
• CHAMPION (England) - RC9YC, RN9YC;
• NGK (Japan) - BCPR6ES, BPR6ES;
• DENSO (Japan) - Q20PR-U11, W20EPR;
• BRISK (Czech Republic) - DR15YC, LR15YC;
• BOSCH (Germany) - FR7DCU, WR7DC.

On the left is the brand of the product suitable for the 16-valve engine, on the right is for. You may notice that the candles with a thin electrode, iridium, etc. were not listed here. A thin electrode is then used to ensure reliable ignition at high speeds (7,000, 8,000 rpm or more), but VAZ engines Above 6,000 rpm, a cut-off is triggered. Iridium candles in their design have a thin central electrode, but as we have already found out, the transition to the use of such parts is a waste of money, and nothing more. Durability iridium candles approximately corresponds to the value of the "life" of a candle with a copper electrode of standard cross-section. We leave the choice to the owner.

Ceramic plaque has appeared - change the candles immediately!

In terms of their operational parameters, including durability, all the components of the listed items are almost the same from each other. This is confirmed by the reviews of car owners expressed in various forums, etc. Perhaps there are more expensive components, the use of which will allow a trivial replacement to increase the power, engine torque or some other characteristics. But having installed such candles in the 21126 motor, most likely you will have to forget about the warranty on the box. With technology it is always like this: you need to imagine what exactly we are doing and what we want to achieve as a result.

Indications for replacing candles:

• If black soot (“chamois”) is present on the insulator cone and electrodes, it can be cleaned or replaced. Cleaning is carried out, including by heating. When replacing, it is better to use candles with a slightly lower glow value than it was before;
• If the surface of the insulator looks like a yellowish glossy ceramic, then the plug needs to be replaced. In this case, the formation of a glassy glaze is taking place. It is electrically conductive.

In the first of the considered cases, carbon deposits are formed because not all elements of the candle are heated sufficiently, and self-cleaning does not occur. This can happen when the car is used for short trips at low speeds, frequent starts and stops. The same effect is characteristic for the operation of the motor at low temperatures. Logically, in such situations, the recommended replacement would be a candle with a lower heat rating than was provided by the manufacturer. You can try to install A14DVRM plugs instead of A17DVRM in an 8-valve engine, and so on. But, similar replacement must be discussed with the dealer.

Comparison of A17DVRM analogues produced under different brands

One of the online publications conducted a comparative test of spark plugs designed for the VAZ-21116 engine. The analogs of the A17DVRM candle supplied by the following companies were tested:

• APS, Bosch, Brisk - Russian production;
• Bosch Platinum, Beru, Finwhale - Germany;
• NGK, Denso - Japan;
• Eyquem - France;
• Champion - "Made in the European Union".

Note that testing was carried out on an 8-valve VAZ-2111 engine (injectors, lambda probe, without catalyst, "January-5.1"). All measurements were carried out at the stand.

The result of the tests performed is shown in the photo in the form of graphs. As you can see, there is still a point in buying imports: the use of Bosch candles, as well as products of the Finwhale, Brisk and Champion brands, will provide a noticeable increase in power. If you want to save on fuel, then ask the stores for NGK products. Additional comments are superfluous here.

Forced engines are characterized by an increased compression value, and VAZ engines. With Brisk spark plugs installed, you don't have to worry about sparks at high pressure. But note that NGK candles have similar characteristics. It turns out that it is NGK products that should be considered the best choice, however, recently there have been fakes under this brand. And the "remake", it seems, is now coming from France, which is described in the film.

In the VAZ-2114 ignition system, the candles are in the leading place, because it depends on them how the engine starts after turning the ignition key. Therefore, it is to this detail, like no other, that much more attention should be paid during the choice. And in this article we will tell you in detail about the design of the spark plug for the VAZ-2114, as well as how to correctly approach its choice.

Features and design of the VAZ-2114 spark plug

Bosch spark plugs with white carbon removed from the VAZ-2114

Spark plugs for VAZ cars, and VAZ-2114 in particular, do not differ from each other, they are exactly the same, receiving a signal in 24 Sq generate a spark, thereby igniting the fuel in the combustion chamber. However, the main and most important structural element in each candle will be the central electrode, because exactly how it will ensure the ignition of the fuel at a certain stage of start-up.

The electrode must be made of heat-resistant, ductile and corrosion-resistant material.

Usually it is made from all kinds of nickel alloys, but models with a "more expensive" price tag, in order to increase efficiency, may contain palladium, copper, iridium, platinum, silver and even gold. All this, according to the manufacturers, was created for easy start-up and the acquisition of a candle of individual properties.

When to change candles?

If you want to change the spark plugs, then this issue should be approached very carefully and carefully, because the efficiency of their work, the total fuel consumption and the transmitted power from the engine to the wheels depend on this choice.

• Numerous tests show that correctly selected plugs for a certain type of engine not only extend its overall resource, but also raise its performance.

Breakdown on the spark plug insulator

The manual from the VAZ-2114 states that the spark plugs must be changed every 30,000 kilometers , because after that, the wear of the electrodes of the factory spark plugs changes and the car behaves completely differently on the road, due to an increase in fuel consumption and a decrease in power.

The condition of the spark plug and the ignition system can be said with confidence by its appearance, depending on the state of the electrode (the presence of carbon deposits, soot, color - approx.).

Visual inspection of candles

What is better to put spark plugs on the VAZ-2114 (survey)?

Today, the choice of spark plugs is very large, and it is not so easy to choose the ones that need to be installed. On most forums, owners of VAZ-2114 cars are most often advised by manufacturers: NGK, Finwhale Champion Brisk Premium Bosch Platinum, DENSO.

Remember that the best spark and the greatest amount of heat will be given by the candle with the thinnest electrode, the size 0,4-0,8 mm, and they are made, as a rule, of alloys of iridium, platinum, palladium and gold.

Also, the situation with a spark, which has platinum, silver or gold plating on its case, is the best. For comparison, the "stock" candle from "DVRM" has a thickness of 2,5 mm, when, as on imported counterparts, it barely exceeds 0,6-0,8 mm, so it's not worth talking about any competition here.

Video on how not to run into fake candles

Pay Special attention on the integrity of the packaging, as well as on the cost of the goods, because fakes, which are quite common today, can be sold at a lower price than the average market price. Therefore, always take each candle out of its individual box and inspect it more closely.

Spark plug manufacturers

Below, we will present each spark plug manufacturer separately, in order to make it easier for you to choose.

Recommended candles for Priora / Kalina / Grant... The manufacturer recommends using domestic spark plugs А17ДВРМ and А15ДВРМ or their imported counterparts. Different spark plugs are used depending on the engine model. For example, candles on Prioru 16 valves: AU17DVRM, and for 8 valves: A17DVRM. Spark plug compatibility table for all VAZ cars:

• Lada Priora: 21120-3707010-00, 21120-3707010-01.
• Lada Kalina: 21110-3707010-00, 21110-3707010-01.
• Lada Granta: 21110-3707010-00, 21110-3707010-03.
• Lada Kalina 2: 21110-3707010-00, 21110-3707010-03.

Types of spark plugs... Candles can differ in the number of electrodes: single-electrode (standard), multi-electrode. And also by type: Regular (standard), iridium, platinum. The manufacturer recommends using conventional single-electrode spark plugs for VAZ.

Spark plug life depends on the operating conditions. In accordance with the regulations Maintenance For cars Lada Priora, Kalina and Granta, spark plugs should be changed every 30,000 km. However, in some cases (for example, when starting the engine in severe frost), new spark plugs can also be damaged by filling them with gasoline. Tip: do not throw out old candles, but use them in such cases.

For stable work It is customary to put Japanese candles NGK VAZ 2106, as well as high-quality products from other foreign manufacturers, on the classic Zhiguli models. "Native" parts of the A17 series, as a rule, are unreliable in operation and have a short service life. But to install imported spark plugs, you need to know which of them are suitable for the "six" in terms of parameters.

Reasons for replacing elements

The spark plug in any car must function in difficult conditions solving the following tasks:

• timely ignite the air-fuel mixture compressed in the cylinder;
• provide an even and powerful spark discharge at its contacts;
• sparking should not deteriorate in any operating mode of the engine.

For ignorant motorists, spark plug testing is reduced to a spark test. Hence, an erroneous statement arises: if, when connected to a source, a spark jumps between the contacts, then the element is completely serviceable.

But the conditions inside the combustion chamber are different from normal atmospheric conditions, since there is a high pressure(over 10 bar), and instead of air - fuel plus heat... Often, a candle that gives a confident spark discharge in air works with gaps in the cylinder or does not spark at all.

It is possible to determine the performance of the elements only at the stand with the high voltage supply and the creation of pressure in the chamber. Such a check is not available to most ordinary motorists, the only way out is to replace the VAZ 2106 spark plugs on time, purchasing high-quality products from well-known manufacturers. These include the renowned brands NGK, Bosch, Beru and Brisk.

Russian candles of the A17 series cannot boast of a long service life and fail after 15-20 thousand km of run, as evidenced by the following signs:

1. The engine is "troit". Moreover, sometimes it is impossible to understand which of the cylinders is failing, since all 4 candles skip ignition cycles.
2. The car does not start well "on cold" and is unstable until warmed up.
3. At high fuel consumption, a drop in power is observed.
4. A particularly neglected case is when the oil pressure lamp comes on. This is the result of a long drive on unusable spark plugs, when non-combustible fuel in the cylinders flows into the crankcase and dilutes the oil, which causes its pressure to drop.

Every motorist should remember that in case of malfunctions in the operation of the power unit, the first thing to do is to unscrew the candles and visually check their condition.

The color and thickness of carbon deposits on the contacts can tell a lot to an understanding motorist:

• black carbon deposits on the contacts indicate that the fuel in the chamber does not burn completely, perhaps the spark plug is out of order;
• white bloom on the electrodes indicates a poor air-fuel mixture, the plug is in good order;
• red soot shows that there are harmful additives in the fuel, the candle is most likely in good order;
• thick "fluffy" carbon deposits are the result of the combustion of oil entering the chamber through the oil seals or the piston group.

The normal color of the electrodes is all shades of brown when minimum thickness plaque.

What parts should I choose?

When choosing spark plugs for a VAZ 2106 car, you must be guided by the numerical value indicated on the marking. It denotes the glow number of the element, which characterizes the ability of the candle to remove heat and self-cleaning from carbon deposits during operation. According to the Russian classification, the elements are divided into the following groups:

1. The heat number from 11 to 16 is a "hot" candle. They are designed for engines with low compression ratios and low power.
2. The same, from 17 to 19. The most widely used candles, including those on VAZ 2101-07 cars.
3. The same, from 20 to 26 - "cold" plugs installed on powerful engines with high degree compression and temperature in the combustion chamber.

If you put too "hot" or "cold" candles on a VAZ 2106 car, then the engine will not be able to function normally with maximum efficiency... Letter indices on the marking indicate less important parameters, but they also need to be taken into account. For example, a product with the designation A17DV is suitable for engines where a carburetor and an ignition system with mechanical contacts are installed, and A17DVRM is suitable for power units with injector.

The trouble is that the classification of imported candles differs from Russian ones, and there is no single measurement system, each manufacturer has its own. Therefore, before buying reliable products from the Japanese company NGK or another brand for the VAZ 2106, it is recommended to study the table.

According to the table, you can select elements from some foreign brands for classic Zhiguli models with different ways fuel supply and types of sparking systems.

Before proceeding with the replacement of the VAZ 2106 spark plugs, you must make sure that the gap between the electrodes in the new parts is 0.7-0.8 mm for cam ignition systems and 0.8-0.9 mm for electronic ones. The gap is measured with a flat probe, in candles with several side electrodes - a round one.

The replacement algorithm is as follows:

1. Switch off ignition and remove high voltage wires with candles, holding them by the tips.
2. Unscrew the old parts and clean the seats with a brush.
3. Screw in new plugs, tighten with medium force.
4. Connect the wires and start the engine.

When connecting high-voltage wires, it is important not to mix them up, so you need to be guided by the markings on the distributor cover.
