What are the good spark plugs on the injector. The best spark plugs for VAZ cars. The best spark plugs with two electrodes

Sometimes motorists do not attach special attention when choosing spark plugs, and in vain. After all, they are the most important components of the entire ignition system, and the efficiency of the engine depends on the quality of timely sparking. The main characteristics for which you need to pay attention to the purchase of candles is a calil number, the size of the spark gap, the ability to self-cleaning, the service life, thermal characteristics, the number of lateral electrodes and working temperature. Let you not scare a large number of characteristics, with a detailed study of them to choose the spark plugs will not be much difficult.

Keep in mind, the service life of the candles is largely depends not only on their design, but also on the serviceability of the engine, power systems. Modern candles for proper choiceInstallation and operation should work up to 30 thousand km mileage.

According to technical Regulations, Spark plugs in engines 21116 and 21126 should be changed during TO-2, that is, after 30 thousand km of mileage. In fact, this period can be extended once a half, if we are talking about gentle mode of operation. But it is not necessary to do so if the car is under warranty (then the replacement is made according to the regulations). Here we will list which spark plugs are suitable for each of the indicated engines. We assume that the owner of "Kalina-2" uses the directories of the following companies: Beru, Champion, NGK, DENSO, BRISK, BOSCH.

• OJSC CALP (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 there is a brand of a product suitable for a 16-valve engine, on the right - for. It can be noted that candles with a thin electrode, iridium, etc. were not listed here. The thin electrode is then used to ensure reliability of ignition at high revs (7,000, 8,000 rpm or more), but vAZ engines Above 6,000 rpm is triggered. Iridiya candles in their design have a thin central electrode, but as we have already found out, the transition to the use of similar details is an excessive money, and no more. The durability of iridium candles approximately corresponds to the value of the "life life" of a candle with a copper electrode of a standard section. Selection Leave the owner.

Appeared from the ceramics - change the candles immediately!

According to its operational parameters, including in durability, all components of the listed names are almost no different. This is confirmed by the reviews of the owners of the car expressed in various forums, etc. Perhaps there are more expensive components, the use of which will allow a banal replacement to increase power, torque of the engine or some other characteristics. But installing such candles in the 21126 motor, most likely, you will have to forget about the warranty on the box. It is always like this: you need to imagine what we do and what we want to achieve as a result.

Indications for replacing candles:

• If there is a black color ("suede") at a cone on the insulator and electrodes, then you can clean or replace. Cleaning is performed, including the heating method. When replacing it is better to use candles with a slightly smaller value of a calil number than it was before;
• If the surface of the insulator looks like a yellowish glossy ceramics, it means that the candle must be replaced. In this case, the formation of vitreous glaze is the formation. It is electrically conductive.

In the first of the considered cases of Nagar, it is formed because not all elements of the candle are heated sufficiently, and self-cleaning does not occur. This can be obtained when the car is used for short trips with low speeds, frequent starts and stops. The same effect is characteristic of the operation of the motor at reduced temperatures. According to logic, in such situations, the recommended replacement will be a candle with a smaller caliling number than was provided by the manufacturer. You can try in an 8-valve motor to install A14 DVRM candles instead of A17DVR, and so on. Only here, such a replacement is necessarily negotiated with the dealer.

Comparison of A17 DVRM analogs issued under different brands

One of the Internet editions conducted a comparative testing of spark plugs intended for the VAZ-21116 engine. Analogues of the Candle of the A17 DVRM, supplied by the following firms:

• APS, Bosch, Brisk - Russian production;
• Bosch Platinum, BERU, FINWHALE - Germany;
• NGK, DENSO - Japan;
• Eyquem - France;
• Champion - "Made in the European Union."

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

The result of the completed tests is shown in the photo in the form of graphs. As you can see, the meaning of buying imports is still there: the use of bosch candles, as well as brand products FinWhale, Brisk and Champion will provide a noticeable increase in power. Want to save on fuel - it means, ask the products of NGK products in stores. Additional comments here are unnecessary.

For forced engines, the increased value of compression is characterized, and VAZ motors. By installing the BRISK ignition candles, you can not worry about the presence of a spark high pressure. But we note that the candles of NGK have similar characteristics. It turns out that the NGK products should be considered an optimal choice, however, recently, fakes appeared for this brand. And Novodel, it seems, now comes from France, what is told in the film.

Spark plugs are not only the most important technical elementfrom which the work directly depends car Engine, but also an excellent diagnostic tool. The state of the ignition candles is the main indicator of the engine performance, the quality of the fuel used, as well as the entire ignition system, in general. As a rule, in VAZ 2107 cars with contact system Ignition and carburetor are used Candles A17DV, however, the candles of such manufacturers are suitable as: Bosh, Brisk, Champion, NGK. For contactless system You can use the ignition candles A17DV-10.

Diagnostics of the automotive motor using spark plugs

As you know, ignition candles are the easiest and most effective tool for diagnosing engine operation. Check the ignition system is best after a small mileage (on a hot engine). If the ignition system is configured in accordance with all the rules of operation, the outdated candles must have light brown raids, and the electrodes must be intact and clean.

Why drops spark plugs on VAZ 2107 injector?

As a rule, the reason for this problem is one. At low temperatures, oxygen requires more fuel, which gives the injector nozzles command to increase the supply of gasoline. With this task, the nozzles cope in conscientiously and felt fuel into the combustion chamber, after which the starter creates quite a strong compression in the cylinders, at the same time feeding the spark for the production of the outbreak. As a result, under the conditions of compression, the spark plugs are launched at a low pulse. Considering the fact that ideal compression is only in a new engine, it is the main cause of the bay of the injector spark plugs.
If you want in the winter season, the VAZ 2107 engine starts normally, and the spark plugs did not bore the flammable, it is necessary at least once a month to "drive" a distance of 50-100 km at a speed of up to 120 km / h. At the same time it is advisable to do it on good gasoline.

Check sparks on candlelight VAZ 2107 Injector

In the case when the fuel pump in the tank is working properly, but the engine does not start, then there is a problem in the ignition system. First of all, you need to check the spark discharge. To check the spark discharge on high voltage wires Use the arrester. In this case, the use of the arrester must, as in injector engines VAZ 2107 uses a static ignition distribution technology with simultaneous supply of high voltage voltage into two candles.

Other engine problems that can be detected during diagnosing:

- electrodes coated with resin naigar indicate a re-secured fuel mixture of the inkorecore operation of the carburetor;
- White raids on the electrodes - too poor fuel mixture;
- burnt electrodes - explicit sign incorrectly selected spark plugs, or the use of poor-quality gasoline;
- The grossiness of the electrodes is talking about the faults of the piston group.

How to replace the candles on the VAZ 2107 injector?

On the correctly running engine VAZ 2107, the ignition candles can be served more than 30,000 km of run. However, it is recommended after every 10,000 km check the candles and, if necessary, clean them.
In the process of checking and replacing the spark plugs, it is necessary to be very careful and neat: the edge of the candle should be cleaned by seating. This will prevent dirt entering the engine cylinders. Also, you should not apply excessive effort, since a large load on the cylinder block may damage them.

In the ignition scheme of VAZ 2114, the candles play a central role. In fact, it is the ignition candles that perform the control signal that comes from the ignition key when it is turned to the start position. After receiving a signal of 24 kV, the candles generate a spark and ignite fuel injected into the combustion chamber. Therefore, drivers vehicle Pay them a lot of attention. In order to choose the right SZ, you need to know the features of their design.

Spark plugs on VAZ 2114 in a constructive plan are no different from the NW used in the ignition systems of other cars. The main elements of this device are:

• case made of metal, with outside It made a hex head under the candle wrench and the threaded part, for twisting into the HBC body, this part perceives 67 percent of the heat released when the candle is triggered and gives 91 percent of this heat to the block of the block head;
• insulator made of corundum ceramics with the addition of aluminum oxide, as well as other rare metal oxides. It is inserted into the metal case;
• thermal cone, often called a heat cone skirt. In fact, this is the lower part of the insulator, it perceives 21 percent of the heat allocated at the moment of sparking;
• at the top of the insulator, the plug head is mounted, an inside of it the contact rod, conjugate with the head, and at the bottom - the central electrode;
• at the bottom of the candle case there is a side electrode, which is located above the protruding part of the central electrode, forming a clearance for the formation of a spark;
• the stubborn part of the case is flat, for better tightness when installing on it, placed a sealing washer;
• for the formation of the strength and tightness of the compounds inside the design, there are ring seals and thermal conducting glass metersmother;
• to combat radio interference with sparking between the contact head and the central electrode, an interference resistor can be installed.

Everything composite elements Candles on VAZ 2114 play an important role, however special attention It is paid to the central electrode. It must have such properties as a heat resistance, high thermal conductivity, plasticity and having high corrosive erosion resistance. For this, it is usually made from various nickel alloys. However B. last years To improve the efficiency of the candle and get any unique properties With its operation, this electrode began to produce from such metals as copper, iridium, palladium, as well as with platinum-casting and silver or gold coated.

How to choose spark plugs for VAZ 2114

To the question of the choice of SZ, if necessary, their replacement should be treated seriously. From how efficiently they work, fuel consumption and engine power depends. Solving which spark plugs are better on the VAZ 2114, the driver must represent what kind of tasks they must perform. Testings that were conducted by experts say that the candle-selected candles can not only improve its indicators, but also to extend the resource. No wonder for the forced engines of sports cars, special candles with copper electrodes having a gold coating are manufactured.

• In the WAZ 2114 operating manual, it is indicated how much to change the spark plugs on the VAZ 2114. It is 30 thousand kilometers of the machine. Of course, good, real factory candles can serve 50 and 70 thousand kilometers. But this does not mean that if with the launch and in the process of movement does not arise any problems, then the candles can not be changed. In fact, as electrodes wear, characteristics are changing. the work of the DVS And with attentive control, it is easy to detect according to the changed indicators at fuel consumption.
• Experts and experienced drivers strongly recommend changing the candles at least in 20 thousand km run, and in winter it is still 10 thousand km. Wherein it is necessary to constantly monitor the operation of the SZ and the gap between the electrodes. On the twisted candle, its condition in the color of the nagar will be seen on the electrodes. Also need to check dryness threaded compound. The presence of fuel or oil on it indicates the absence of tightness in the system.
• Selection of SZ in auto parts stores today is large enough and to determine which candles to put on VAZ 2114, you need to study specifications All proposed models. In the forums and in car magazines, the ignition candles with brands "NGK", "FINWHALE" "CHAMPION" "BRISK PREMIUM" "BOSCH PLATIN" are recommended for VAZ 2114. For example, when passing test tests, these kits when comparing them with Russian A17DMERs from Engels showed 5-6% better power and 3.5-4.5% the best fuel consumption. Despite the fact that foreign candlesticks are much more expensive than domestic, due to the reduction of fuel consumption, they pay off for half a year.
• The advantages of imported candles are best visualized when checking on a special motor bench With photographing the sparking process. A simple one -electrode candle with a nickel electrode gives intermittent multicolored, randomly flying in different directions, a spark. Candles from imported sets in sparking create a solid cone of white fire.
• The color sparks of the auto electrician are determined by the efficiency of the candlestone. If the color is red - then it means the spark is weak intermittent. Blue or blue color means a more intense spark. White fire means the spark is intense and stable. It is such a fire that gives intensive ignition of fuel-air mixture when injected. And this means the best combustion, an increase in engine power and less fuel consumption.

• The best spark gives candles with the finest electrodes, 0.4-0.6 mm thick. Such electrodes are made from iridium, palladium or platinum and gold alloys. Significantly improves the "spark" spraying on the central and lateral electrode of silver, gold or platinum. The thickness of the electrode of the A17 candle from Engels is 2.5 mm. Therefore, it does not withstand competition with expensive imported candlesticks.

Determine the fake is the easiest on sale price. As a rule, such "products" is sold for half the real value of the "original". It immediately should alert the buyer. Also before installing check the candle itself. In fakes, it is often possible to find the swinging plug head.

Choosing candles for VAZ 2114 It is necessary that it is often quite often in our trading network there is counterfeit products, that is, "self-made" under well-known and expensive brands. If accidentally install such candles on the machine, it is good if you calmly drive one thousand kilometers.
