Which spark plugs are better for VAZ? Spark plugs for VAZ 2115 injector 8 valves

Any internal combustion engine will not start operating without 2 main factors - the air-fuel mixture and its ignition. If the saturation of the fuel with oxygen is facilitated by the air supply system (air filter, throttle), then the VAZ 2114 spark plugs are responsible for ignition.

The principle of operation of the product is that operating voltage from the battery is supplied to the spark plug through the ignition coil, as a result of which the device produces a spark that ignites oxygen-enriched gasoline directly in the cylinder.

The device of spark plugs VAZ 2114

Products come in several types: classic (two-electrode) and multi-electrode. In addition, they are classified according to such criteria as: material of manufacture, size, heat rating (cold or hot). In addition, for a particular device there are standards regarding the size of the gap between the electrodes. In relation to the VAZ 2114, a classic design is used. Main components:

side and central electrodes (responsible for generating a spark);
frame;
resistor;
insulator;
contact (to which the high-voltage wire is connected).

Keep in mind that spark plugs for the VAZ 2114 (injector) may not be suitable for cars of other brands and vice versa.

What are the Best Spark Plugs in 2022 ()

Which spark plugs are best for your car ? Surely every car owner has asked this question at least once. After all, the choice is influenced by several factors - the size of the spark plug, the heat rating, its type, the size and type of engine (carburetor/injector), the fuel used (gas/gasoline) and so on. You should also take into account the car manufacturer's recommendations.

Signs of faulty spark plugs

Malfunctions directly affect the operation of the internal combustion engine (misfire, engine tripping, failure of one or more cylinders and other problems). The most common signs that indicate a malfunction are: - disturbances in the operation of the ignition system (the car is difficult to start); — increased fuel consumption; — deterioration of the dynamic qualities of the internal combustion engine.

An important parameter that affects the operation of the product (the production of a proper spark) is the gap of the VAZ 2114 spark plugs between the side and central electrodes.

Troubleshooting

Fortunately, a performance check is available to every car enthusiast and does not depend on technical equipment or the availability of expensive diagnostic equipment. There are several simple, common ways to conduct an independent test: 1. Analysis of the presence and quality of the spark. 2. Testing using a multimeter.

In order to use the first method, it is necessary to dismantle and clean the working surface of the spark plug. Next, a high-voltage wire is connected to the spark plug, the housing is brought to the power unit and the starter is started briefly (for a few seconds). Normal operating parameters are the production of a clear, blue spark. Evidence of a malfunction is a yellowish, reddish color of the spark or its complete absence. The second way is as follows. We take a multimeter and switch the measuring mode of the device to 20 kOhm. We attach the red probe to the side electrode, and connect the black one directly to the contact (where the high-voltage wire is put on). We measure the resistance readings on all four products. Normal resistance levels range from 2 to 4 kOhms. If the indications are different, normal operation of the internal combustion engine is not guaranteed.

Replacing spark plugs for VAZ 2114

To carry out all the work we will need the following tool: - a special spark plug wrench; — a set of metal probes for measuring the gap between the electrodes.

To perform the replacement, follow the following sequence of actions:

Carry out all work with the car's ignition turned off. In addition, in order to avoid burns, it is best to perform all manipulations on a cooled engine.
Open the hood of the car. Determining the location of the spark plugs is not difficult; they are located directly on the cylinder block, or rather on its side. The location is easy to locate by the connected four thick high-voltage wires.
Disconnect the negative terminal of the battery.
Disconnect the high-voltage wires from each spark plug one by one. This is done quite easily, you just need to pull the wire with a little effort.
Now we need a spark plug key. Keep in mind that they come in different types, so before buying such a tool, check with the seller what you need specifically for the VAZ 2114.
Using a key, unscrew each element from the block one by one. At the same time, remember, or better yet, mark which spark plug is removed from which cylinder.
Clean the working holes in the cylinder from possible traces of carbon deposits or fuel. This can be done with a clean rag.
Reinstall.

At this point, the work related to replacing the spark plugs of the VAZ 2114 (8 valves) is completed.

In the ignition system of the VAZ-2114, spark plugs 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 selection. 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 choose the right one.

How to check spark plugs in a VAZ 2107 - step-by-step instructions

Attention: When performing the following operation, do not pull on the high-voltage wire. Force should only be applied to the tip of the high-voltage wire.

Remove the tip of the high-voltage wire from the spark plug.
We clean the dirt from the cylinder head and blow it with compressed air around the spark plug.
Using a 21mm spark plug wrench or a deep socket wrench, remove the spark plug from the threaded hole in the cylinder head.
Visually assess the condition of the spark plug.
For a working spark plug, when the engine is adjusted on a VAZ 2107 car, carbon deposits on the spark plug insulator should be from gray-yellow to gray-brown. If carbon deposits on the spark plug are black, the spark plug may be faulty or the engine adjustments may be incorrect. If the spark plug insulator is cracked or damaged, the spark plug must be replaced.
Using a round feeler gauge, check the gap between the electrodes at the spark plug. If the spark plug gap does not meet the standard, set the spark plug gap according to the table. 13.3, bending or bending the side electrode.
We install a spark plug in the engine of a VAZ 2107 car, wrapping it by hand, and then tighten it with a wrench to a torque of 3-4 kgf-m.
Similarly, we replace the spark plugs of other cylinders on a VAZ 2107 car.

Caution: Over-tightening the spark plug may damage the cylinder head bore threads.

Features and design of the VAZ-2114 spark plug

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

Spark plugs for VAZ cars, and VAZ-2114 in particular, are no different from each other, they are exactly the same, receiving a signal of 24 kV

generate a spark, thereby igniting the fuel in the combustion chamber. However, the main and most important structural element in each spark plug will be the central electrode, because it will ensure ignition of the fuel at a certain stage of startup.

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

It is usually made from all kinds of nickel alloys, but models with a more expensive price tag, in order to increase efficiency, can contain palladium, copper, iridium, platinum, silver and even gold. All this, according to manufacturers, was created for easier starting and the acquisition of individual properties of the candle.

When to change spark plugs?

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

Numerous tests show that correctly selected spark plugs for a certain type of engine not only extend its overall service life, but also improve its performance.

Breakdown on the spark plug insulator

The manual from the VAZ-2114 states that spark plugs should be changed every 30,000 kilometers.
, because after this, 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 determined with confidence by its appearance, depending on the condition of the electrode (presence of soot, soot, color - approx.).

Which spark plugs are best for the VAZ-2114 (survey)?

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

Remember that the best spark and the greatest amount of heat will be given by the spark plug that has the thinnest electrode, the size 0,4-0,8

mm, and they are made, as a rule, from alloys of iridium, platinum, palladium and gold.

Also, the situation with a spark that has a coating of platinum, silver or gold on its body has the best effect. For comparison, a “stock” candle from DVRM has a thickness of 2,5

mm, when, like on imported analogues, it barely exceeds
0.6-0.8
mm, so there is no point in talking about any competition here.
