What should be the correct gap on the spark plugs of a VAZ-2114

Many VAZ-2114 owners have encountered adjusting the gap on the spark plugs. But not everyone fully understands what this indicator should be, because it can become a problem that motorists face. the gap on the spark plugs, what it should be, how the gap in the spark plugs affects idle. What should be the gap on the VAZ-2114 spark plugs? What is the mileage of these here to bend it so that the gap becomes on the first and fourth candles. These may include improper operation of the engine, poor starting, failure to start the engine, and also the car will stall and stall.

To correct it, you need to bend the outer electrode or move it out a little.

After the adjustment, it is worth measuring the gap again. The procedure continues until the spark plug distance between the electrodes reaches the established standards.

Note. Many motorists believe that in automotive spare parts stores, spark plugs are sold with the gap already set. But that's not true. Since spark plugs are the same type for many brands and models, they have a standard gap of 1 mm.
Therefore, after purchasing a new set, you need to set them according to the specified size.

Module replacement

Replacement is a fairly common solution to the problem of a faulty ignition module. The procedure is performed as follows:

  • Locate the ignition module. If anything, high voltage wires go from the spark plugs to it. You can't go wrong;
  • Remove the negative terminal from the battery;
  • Disconnect the wiring block from the ignition module;
  • Turn off the high voltage;
  • Dismantle the module and remove it;
  • Place a new coil, or rather a module, in place of the old device, and reassemble in the reverse order;
  • Please do not confuse the location of the high voltage wires on the module, otherwise you will have to buy a new component;
  • For preventive purposes, it would not be a bad idea to replace the old wires. Especially if there are yellow stripes on the tips of the spark plugs and on the wiring themselves. This is clear evidence that the elements must be replaced.

Effect of incorrect clearance on engine performance

As practice shows, many motorists make the same mistake - install spark plugs without adjusting the spark plug gap between the electrodes. what should be the gap on the spark plugs, we look and do VAZ 2115,2114,2113,2199,2109,2108 This can lead to the following consequences:

  • A large gap leads to increased consumption of the fuel mixture. Many car enthusiasts may be pleased with the appearance of additional dynamism and traction until they see a consumption of 12-15 liters per 100 km. Another indirect indicator may be gas dips or a jerking effect. This will not only affect consumption, but also the wear and tear of the motor itself.

Black soot is the first sign of a very rich mixture.

WHAT TO DO IF IT'S FLOODED?

Every car owner should know what to do when the spark plugs are flooded. Most often, motorists encounter this problem when operating a vehicle in the cold season. In such cases, purging the motor will help. To do this you need to have with you:

Spark plug keys

Next steps will be as follows:

  1. Remove the protective casing on the engine (if equipped);
  2. Disconnect high-voltage wires from ignition devices;
  3. Turn them out of the cylinder head;
  4. Disconnect the wires from the ignition unit;
  5. Press the gas pedal to the limit and crank the engine with the starter for about 7-10 seconds;
  6. Now you can put the candles;
  7. Connect high voltage wires. Each wire fits a specific spark plug, try not to confuse them;
  8. The connector from the ignition unit is put in place.

Now you can try to start the engine. Some drivers warm up “flooded spark plugs” using accessible methods.

Driver tips and reviews

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

Spark plug device for VAZ 2114

In terms of design, the spark plugs for the VAZ 2114 are no different from the SZ 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;

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.

Self-identification of problems

The procedure is not difficult. The easiest way is visual. The most difficult one involves a detailed study of the engine’s performance.

One of the obvious signs of these breakdowns is a malfunction in the engine. For example, it may be difficult to start, or it may have an idle speed.

Other signs are:

  1. The first is related to the rotation of the crankshaft. If it rotates at the required frequency, but the engine itself does not start, this is a sign of lack of ignition. In other words, the air mixture does not ignite.
  2. If a mixture of fuel and air flares up in the cylinders, the engine may operate extremely unstable.
  3. When starting the engine, the starter does not function. As a result, the engine also fades out.
  4. Very high fuel costs. If the composition of fuel and air does not ignite, then the power of the power unit is reduced or drops to zero. Power losses can be compensated by supplying an increased dose of fuel to the cylinders. And the result is an impressive waste of fuel.
  5. The catalyst is not working. If there is no ignition in the technology, there is no combustion of the air-fuel composition. And the fuel that does not ignite ends up in the catalyst. And there it oxidizes. And the catalyst stops functioning.
  6. A cold engine does not start well. When turning the ignition, cold ones accumulate condensation. And it is considered an excellent conductor of electricity. If the distance between the electrodes increases, then the degree of breakdown voltage should develop. It cannot be developed independently, because the energy will be eliminated through the indicated electrodes, as well as through a ceramic cone.
  7. There are traces of mechanical defects on the surface. This is a sign of either complete breakdown or malfunction.
  8. There are carbon deposits and deposits on the electrodes. The candles themselves smell like fuel. This is evidence that the system itself, and every single one of them, is faulty.
  9. A damaged cable carrying high voltage can seriously impair normal operation.

The frequency of replacing spark plugs and the consequences of missing the deadline

It is difficult to indicate a specific mileage or time period during which the spark plugs need to be replaced. For example, many car manufacturers, as well as spark plug brands, recommend replacement at least once every 15,000 kilometers. This is obviously due to the service interval of most machines. After all, many vehicle owners do not change anything in the car themselves, but wait for service.

Indeed, such a period seems quite reasonable, unless you drive about 5,000 kilometers per year. In such a situation, it is better to change the spark plugs every year, at least. Also, replacing spark plugs may be required before this date or before reaching 15,000 kilometers. This is due to low-quality fuel or special operating conditions. The consequences of untimely replacement are as follows:

  • lack of complete combustion of fuel and its proper ignition in the upper part of the chamber;
  • increased consumption of gasoline or diesel fuel, which is unacceptable at current resource prices;
  • causing various problems in the electrical system of the car that may affect the performance of the car;
  • current breakdown to the engine and car body when the spark plug completely fails;
  • clogging of filters and passages in the exhaust system, as well as directly inside the engine, with soot;
  • other problems that lead to a decrease in the life of the power unit and other components.

Such consequences will obviously be much more expensive for the vehicle owner than a timely solution to problems with spark plugs. Considering the low cost of spare parts of this type, replacement will not cause financial difficulties. Even the most expensive spark plugs cost moderate money. It is better to choose the right element according to the manufacturer's recommendations.

Each car has its own requirements for spark plugs, so you should listen to the manufacturer’s advice and not violate the technical regulations for operating the car. Otherwise, you will definitely have to spend some money to solve the problems that have arisen. It is better to use high-quality candles of a certified type than to spend a lot of money solving problems when using poor equipment.
