Spark plugs for vases: selection by car, which ones are best for contactless ignition

Candle set

Any motorist knows that spark plugs are used in a gasoline engine. The principle of their operation is quite simple and intuitive, but they can still hide many problems. The service life of spark plugs is very long, it all depends on whether the carburetor or injector supplies fuel. It should be noted that replacing a spark plug on a VAZ 2107 may not bring the expected result, since the service life of parts is affected by the technical condition of the engine and other systems.

For the VAZ 21074 carburetor, only those models of spark plugs that are designed for this type of injection are suitable. If an injector is installed in the car, the requirements will be slightly different. The type of ignition system is also important in determining the spark plug parameters used for a particular engine. In addition, many problems can be diagnosed by the color of the electrode. Experience and logic will help answer the question why candles are black or reddish.

Which spark plugs for VAZ are better to choose?

There are a large number of different modifications of the part, which complicates life for motorists. The problem is that each motor is designed for a specific type of spark plug. If you supply the wrong part, a number of negative consequences can arise.

1. Misfire of the mixture due to the gap between the electrodes of the element being too wide.
2. Interruptions in the operation of the internal combustion engine caused by too low spark power.
3. Instant failure of the device due to too much electrode protrusion.

Also, depending on the inconsistencies present, other malfunctions may “pop up” that reduce the comfort of using the car.

What to look for when choosing.

Specialists from the AvtoVAZ plant recommend selecting spark plugs according to a number of parameters.

1. Heat number. The parameter characterizes the rate of heat removal from the working part of the candle. At the same time, the electrode transfers excess heat to the spark plug skirt in a timely manner, which ensures stable operation of the part. If energy is removed too quickly, scale forms on the working part of the part, which prevents normal spark breakdown. If the withdrawal is too slow, the thin electrode overheats. The process provokes the formation of glow ignition. This prevents the engine from operating normally due to detonation of the mixture or its early ignition. Under normal thermal conditions, a spark adequately breaks through the spark plugs and does not form excessive carbon deposits.
2. Spark gap. Some users know that for the engine to operate correctly, the spark gap on the spark plugs must be maintained. The working gap on VAZ spark plugs is strictly set by the manufacturer of the power plant and is necessary due to the fact that the formed electric arc has a certain strength. As the distance increases, the spark loses stability, which can lead to misfires. In the opposite case, easier starting of the engine is ensured, but when the gas is released, the electric arc current may not be enough. This is justified by the fact that each ignition coil has a certain transformation ratio, usually equal to 2000 units. This means that during the start-up of the internal combustion engine, the elements produce up to 14 kW, and during normal operation it is already 24. Consequently, failure to comply with this parameter can lead to serious disruptions in the operation of the motor.
3. Departure of the working part of the electrodes. The parameter is critical for adequate operation of the power plant. The spark plugs on the VAZ 8-valve injector, as well as for carburetor models, have electrodes strongly pushed forward. This is due to the fact that the structural parts are located in the corner of the combustion chamber, where there is no adequate ventilation. The overhang of the working part allows for better ignition of the mixture and stabilizes engine operation. If the spark plugs are mounted in a multi-valve engine, where the inserts are located in the center of the valve head, it is recommended to install spark plugs with a deep-set core - this will prevent damage to the electrodes by the piston bottom and an abundance of carbon deposits on the structural elements.
4. Number of electrodes. Initially, manufacturers position this parameter as a definite plus. When one electrode “burns out,” the spark plug switches to another, which significantly increases its service life. However, not everything is as simple as it seems at first glance. If the mixture is sprayed unevenly in the cylinder (poor ventilation of the combustion chamber), and at this moment the spark jumps to the shadowed part (the place where the exhaust remains), misfire may occur, which will lead to unstable operation of the power plant. Additionally, this fact increases the wear of the catalyst and engine oil, which is critical for VAZ cars.
5. Manufacturer. The manufacturer of the product is also an important parameter. Users recommend buying from trusted brands that have been on the market for a long time. The cost of such candles will be significant, but with proper selection and operation they will work for a long time and without significant complaints.

By adhering to the specified parameters, a car enthusiast can buy a fairly high-quality product, while saving on the frequency of car servicing and repairs.

How to remove black carbon deposits from ignition elements

The gradation of electrode colors from light gray to white (light yellow is also possible) is evidence that the engine is running on a lean mixture. Related reasons may be:

• The product is too hot. The heat rating of the product is lower than that recommended by the manufacturer.
• Large ignition timing angle.
• Using low octane gasoline.

There is no point in delaying in finding out the circumstances that caused this soot-colored condition on the new spark plug. A lean mixture directly causes overheating of both the igniter and the combustion chamber. Ultimately, this situation can lead to burnout of the exhaust valves.

When analyzing the factors that caused a poor quality mixture, it is useful to check for the presence of abnormal glow ignition. A symptom indicating its presence is the reluctance of the engine to stall when the ignition is turned off. In total, this means that the “match” was not created for this engine.

Automakers provide specific recommendations on how often spark plugs need to be checked and replaced. Let us clarify that the data indicated in the technical documentation is somewhat exaggerated by the manufacturer, and motorists are forced to change them more often than stated. If you suspect wear or poor condition of the spark plugs, you can determine their condition quite easily by carefully examining the shade of soot formed on the surface of the electrodes. This allows you to determine which systems and components of the vehicle lead to incorrect operation of the elements.

Carbon deposits can be removed from the ignition elements mechanically or using cleaning agents.

The simplest cleaning method is to remove carbon deposits using sandpaper or a metal brush. Although this method is attractive in its simplicity, professionals do not recommend using it to clean black candles in order to avoid removing the thinnest deposit of precious metals applied to the electrode of the product.

Mechanical cleaning method

Chemical method

It is no coincidence that car owners prefer to clean elements using a chemical method. Black carbon deposits from candles can be easily cleaned using conventional cleaning products designed for cleaning tiles and plumbing fixtures. Cleaning requires a small container, a rag and a toothbrush.

1. Place the elements in a basin (bucket) and fill them completely with the prepared solution.
2. Leave in the solution for 30 minutes (more is possible).
3. Clean the element with a toothbrush.
4. Rinse in running water and wipe dry with a cloth.

Before putting the elements in place, you need to dry them well. To do this, place them in the oven for 20 minutes or blow them with a hairdryer at minimum power.

Which spark plugs to choose for a VAZ 2114

VAZ 2113, 2114 and 2115 (Samara-2 series) are very similar in design, have a common platform and are equipped with the same engines - 1.5 (VAZ-2111, 77 hp) and 1.6 (VAZ-21114, 82 hp . or VAZ-11183, 81 hp).

Spark plugs for VAZ 2113/2114/2115 do not differ in any way depending on the configuration, year of manufacture of the car, or the installed engine. The same spark plugs are installed on all 3 cars. The original manufacturer is the Russian company “E3 3.9”, Engels. What is noteworthy is that the production facilities of this company belong to Bosch. Spark plugs for VAZ 2113, 2114, 2115 – which ones to install?

On VAZ 2113/2114/2115 with 1.5 and 1.6 liter engines, spark plugs should always be placed under article number 21110-3707010-86. It is also found under other numbers - 21110-3707010-00 or 2111-3707010. In fact, these are all the same spark plug. In the manufacturer's catalogs it has the article number A17DVRM. This spark plug has a central nickel electrode, single-contact, short thread, tightening torque - 22 Nm.

The dimensions of the original spark plug are shown below.

* according to Champion nomenclature (Russian standard)

Original candles, as a rule, are usually sold in branded packaging from LADA. Less often you can find them directly from the manufacturer - the Engels plant. They come from the manufacturer a little cheaper. The reviews from most drivers about this spare part are positive, and there are not too many fakes on the market, due to the fact that they do not have a very high price.

What analogues are there?

The most famous substitutes for the originals from other manufacturers are presented below.

NGK BPR6ES

Denso W20EPR-U

Bosch 0242235663

In addition to conventional (nickel) analogues, more modern platinum or iridium spark plugs are also somewhat popular. They are installed to achieve a slight improvement in the dynamic characteristics of the engine. This is achieved thanks to a thinner electrode than nickel models. In addition, they last several times longer. For VAZ 2113, 2114 and 2115, the most popular are platinum Bosch 0242235540 at 200 rubles/piece, or iridium DENSO IW20TT, 610 rubles/piece.

When to change spark plugs on a VAZ 2113/2114/2115?

According to the maintenance regulations for VAZ 2115, 2114 and 2113, spark plugs must be changed every 30 thousand km. But, as the experience of drivers shows, this period needs to be reduced by half on average, and in fact, replacement needs to be done every 15 thousand km. This is influenced by many factors, the main ones being fuel quality and operating conditions.

According to the rating of spark plugs for VAZ 2113/2114/2115 on PartReview dated 05/04/20, owners prefer BRISK 3.9 products. Manufacturers also stand out: NGK 3.7, Bosch 3.8 and Denso 3.8.

Selection of spark plugs for VAZ 2114

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

Design and features of the use of spark plugs for VAZ cars

The design of a spark plug for a VAZ 2114.
In terms of design, spark plugs for a VAZ 2114 are no different from the spark plugs used in the ignition systems of other cars. The main elements of this device are:

• the body is made of metal, on the outside there is a hex head for a spark plug wrench and a threaded part for screwing into the cylinder head housing, this part absorbs 67 percent of the heat generated when the spark plug fires and transfers 91 percent of this heat to the cylinder head housing;
• an insulator made of corundum ceramics with the addition of aluminum oxide, as well as oxides of other rare metals. It is inserted into a metal case;
• thermal cone, often called the thermal cone skirt. In fact, this is the lower part of the insulator; it absorbs 21 percent of the heat released at the moment of sparking;
• a plug head is attached in the upper part of the insulator, inside it there is a contact rod mated to the head, and in the lower part there is a central electrode;
• on the lower part of the spark plug body there is a side electrode, which is located above the protruding part of the central electrode, forming a gap for the formation of a spark;
• the thrust part of the body is flat; for better tightness during installation, a sealing washer is placed on it;
• to create strength and tightness of connections inside the structure, there are ring seals and a heat-conducting glass sealant;
• To combat radio interference that occurs during sparking, a noise suppression resistor can be installed between the contact head and the central electrode.

All components of the spark plug on the VAZ 2114 play an important role, but special attention is paid to the central electrode. It must have such properties as heat resistance, high thermal conductivity, ductility and have high corrosion and erosion resistance. For this purpose, it is usually made from various nickel alloys. However, in recent years, in order to improve the efficiency of the spark plug and obtain any unique properties during its operation, this electrode began to be produced from metals such as copper, iridium, palladium, as well as with platinum deposition and silver or gold coating.

How to choose spark plugs for VAZ 2114

The issue of choosing SZ if it is necessary to replace them must be taken seriously. Fuel consumption and engine power depend on how efficiently they work. When deciding which spark plugs are best for the VAZ 2114, the driver must imagine which task they should perform. Testing conducted by specialists suggests that correctly selected spark plugs for a specific engine can not only improve its performance, but also extend its service life. It is not without reason that special spark plugs with copper electrodes coated with gold are made for the forced engines of sports cars.

• The VAZ 2114 operating manual indicates how long it takes to change the spark plugs on a VAZ 2114. This is 30 thousand kilometers of the car. Of course, good, real factory spark plugs can last 50 and 70 thousand kilometers. But this does not mean that if no problems arise with starting and during movement, then the spark plugs do not need to be changed. In fact, as the electrodes wear out, the operating characteristics of the internal combustion engine change, and with careful monitoring this can be easily detected by the changed indicators in fuel consumption.
• Experts and experienced drivers strongly recommend changing spark plugs at least every 20 thousand km, and in winter even after 10 thousand km. In this case, it is necessary to constantly monitor the operation of the SZ and the gap between the electrodes. When the spark plug is unscrewed, its condition will be immediately visible by the color of the carbon deposits on the electrodes. It is also necessary to check the dryness of the threaded connection. The presence of fuel or oil on it indicates a lack of tightness in the system.
• The choice of spark plugs in auto parts stores today is quite large, and in order to decide which spark plugs to put on the VAZ 2114, you need to study the technical characteristics of all offered models. On forums and in automobile magazines, spark plugs with the brands “NGK”, “Finwhale” “Champion” “Brisk Premium” “Bosch Platin” are recommended for the VAZ 2114. For example, when passing tests, these kits, when comparing them with the Russian A17 DMRV from Engels, showed 5-6% better power and 3.5-4.5% better fuel consumption. Despite the fact that foreign spark plug kits are much more expensive than domestic ones, due to reduced fuel consumption they pay for themselves in six months.
• The advantages of imported spark plugs are best seen when checking them on a special engine stand and photographing the spark formation process. A simple single-electrode spark plug with a nickel electrode produces an intermittent multi-colored spark randomly flying in different directions. Spark plugs from imported kits create a solid cone of white fire when sparking.
• Auto electricians determine the efficiency of a spark plug kit by the color of the spark. If the color is red, it means the spark is weak and intermittent. Blue or cyan color means a more intense spark. White fire means the spark is intense and stable. It is this kind of fire that gives intense ignition of the fuel-air mixture during injection. This means better combustion, increased engine power and lower fuel consumption.

Spark plug spark

• The best spark is produced by spark plugs with the thinnest electrodes, 0.4-0.6 mm thick. Such electrodes are made of iridium, palladium or alloys with platinum and gold. Significantly improves the “spark” by sputtering silver, gold or platinum onto the central and side electrodes. The thickness of the electrode of the A17 spark plug from Engels is 2.5 mm. Therefore, it cannot compete with expensive imported spark plug kits.

The easiest way to spot a fake is by the selling price. As a rule, such “products” are sold for half the real cost of the “original”. This should immediately alert the buyer. You should also check the spark plug itself before installation. On fakes you can often find a swinging plug head.

When choosing spark plugs for the VAZ 2114, it is important to remember that quite often in our distribution network you can find counterfeit products, that is, “homemade” products under well-known and expensive brands. If you accidentally install such spark plugs on a car, then it’s good if you can easily drive it for one thousand kilometers.

Noble metals: practical meaning of application

As we already said in the last paragraph, the transition to a multi-electrode circuit did not bring much practical benefit in increasing the service life of spark plugs. In fact, the fight against the very cause of natural wear of spark plugs, that is, erosion of contacts, was replaced with a palliative - the substitution of “spare” ones. To increase the immediate reliability of the electrodes, the design of the spark plugs was significantly redesigned.

In “platinum” and “iridium” spark plugs, the main feature that catches the eye is a very thin central electrode, which precisely localizes the point of origin of the spark - opposite it, a plaque of the corresponding metal is soldered on the side electrode, and the central electrode is also covered with it.

The advantages of such candles are obvious: the electrodes have a service life that, under normal conditions, is two to three times longer than that of conventional candles. The thin central electrode is perfectly self-cleaning, which also contributes to reliable operation.

The disadvantages, alas, are also significant. The first is the price: a set with the Platinum or Iridium inscription will cost at least two to three times more than regular candles. The second, oddly enough, is tenderness: non-fading carbon deposits instantly kill such candles, and mechanical cleaning is contraindicated for them, just like the old-fashioned burning with a torch. First of all, we are, of course, talking about the notorious ferrocene, which is still not uncommon to encounter.

What are the best spark plugs for a VAZ 2114?

One of the most popular domestic cars. Built on the VAZ 2109 platform. Sporty appearance, good technical performance, excellent cornering, excellent weight control - these are its main characteristics.

Initially, the model was presented with a 1.5 liter 8 valve engine. Ten years ago, a car appeared with a 16-valve 1.6-liter engine and 77 horsepower. Two years later, the manufacturer increased the power to 89, in 2010 to 98. The transmission is 5-speed, fuel consumption in the city is 7 liters, on the highway - about 9 liters per 100 km.

The operation of an internal combustion engine depends on the air-fuel mixture and its ignition. The throttle, air filter and spark plugs are responsible for this. The latter lose their useful properties during operation and require replacement with new ones.

The main signs of spark plug failure

The appearance of spark plugs can tell not only about their operation, but also about malfunctions of both the fuel system and other engine systems. What are the signs of a faulty spark plug itself?

So that drivers can understand from the behavior of their car that it is time to replace the spark plugs, let us recall the main signs of their malfunctions:

• misfires and engine tripping;
• the smell of gasoline;
• increased fuel consumption;
• deterioration in dynamics;
• glow ignition;
• brown color and cracks at the bottom of the insulator.
