Differences between candle products

First of all, our brothers in the garage community should tell those who are not in the know and remind those who have forgotten that spark plugs can differ from each other not only by manufacturer brands, but above all by:

according to the size of the hexagons, or as they say in our garages, there are spark plugs either on a turnkey basis for 21 or 16;
according to the length parameters of the threaded parts of the candles, they are shortened, equal to 19 mm, and elongated, equal to 26.5 mm;
candles can vary in thread diameter, starting from 10, 12, 14 and ending with 18 mm diameter of the threaded part. As for the thread pitch parameter, as a rule, it is 1.25 mm;
according to electrode materials, such as cheap copper/nickel, as well as expensive iridium/platinum;
according to heat numbers. As for the glow numbers, these parameters are nothing more than indicators of the time during which the electrodes of the spark plugs reach such a temperature when spontaneous detonation of the fuel mixtures begins, which is called glow ignition.

To the displeasure of garage left-handed engine mechanics who take advantage of having experience in selecting spark plugs with certain heat ratings for certain specific engines, we have the opportunity to provide our garage fellow humanities with a table of comparisons of the glow parameters of products between different src=»https: //ixray.ru/wp-content/uploads/2021/11/Table-of-comparisons-of-glow-numbers-of-candles-from-different-manufacturers_1.jpg" class="aligncenter" width="1024″ height="917″[ /img]

reliable Japanese manufacturer;
durability;
excellent performance parameters;
the ability to reduce fuel consumption when installing these spark plugs in the engine.

low cost;
good workmanship;
convenient installation in the engine;
versatility of use;
ease of replacement.

Minuses:

some copies quickly fail.

How to choose spark plugs

As mentioned above, candles are an important element in any car, so their choice must be approached responsibly. Engine starting, speed and even fuel consumption depend on them. You need to choose based on these points:

the more electrodes, the better, the candle will last a long time;

pay attention to the gap. It should be minimal. When the spark plugs wear out, the gap becomes wider, putting stress on the ignition coil, and it may fail;

focus on price. If you have an inexpensive old domestic car, there is no point in overpaying and choosing expensive spark plugs. All of the above brands also have budget candles;

Don't run into a fake. Buy candles only from trusted places and auto stores or gas stations. There may be counterfeits in online stores or hypermarkets;

If you can’t choose a candle yourself, contact a specialist for help.

Replacement and maintenance points

What are the best spark plugs? The manufacturer strongly recommends installing spark plugs on the VAZ-2190, version 8 valves that meet the standards of the AU17DVRM brand. These products are of domestic origin, or more precisely, they are manufactured at ZAZS Russia OJSC.

Catalog code – “21110-3707010-00”.

If we consider foreign analogues, we should highlight the following:

"WD7DFC", produced by the German giant "BOSCH";
“BCPR6” from the “ES-11” series from the Japanese brand “NGK”;
"DR15YC" from the BRISK corporation (Czech Republic).

Each car owner decides for himself which spark plugs are best.

The entire set (4 pcs.) should be replaced. When choosing the parts you are looking for, pay attention to their technical characteristics. The following set of parameters will be relevant for a candle:

diameter of the threaded section;
its length;
heat number.

The purchased spark plugs must fully comply with the needs of the LADA Granta engine in terms of the indicated characteristics.

How to adjust the gap?

Performing maintenance involves cleaning the electrodes from accumulated carbon deposits and adjusting the gap. This parameter should not be allowed to exceed the manufacturer’s permissible requirements. The process of the spark plug involves reducing the height of the central electrode with the simultaneous formation of a rounded depression on the inner sphere. This implies an increase in the gap, the value of which is subject to adjustment. It is set using probes and corresponds to the limits of 1.0 - 1.5 mm. If the gap is set correctly, the probe will penetrate between the electrodes with a noticeable tension.

Clearing away cinder deposits

You should resort to this procedure if the need arises and cinder deposits have accumulated on the electrodes. Here we do not recommend using pointed objects made of hard steel. Use a wire brush with soft bristles or sandpaper. Alternatively, you can resort to cleaning using a chemical or thermal method.

Inspect the condition of the electrodes after 10 thousand km or earlier, if the engine prompted this by its capricious operation. If the intensity of use of a LADA Granta car is low, then inspect the spark plugs once a season (twice a year).

Replacing spark plugs is very common, and the owner of a Lada Granta is not provided with a full guarantee of the high-quality functioning of the system and, accordingly, the engine. Also, no one will undertake to claim that the new spark plug will withstand the regulatory service life of 30 thousand km.

We change spark plugs if the following circumstances occur:

there were signs of a poor (not the first time) engine starting;
the unit is troit;
traction performance has deteriorated significantly;
mileage exceeded its regulatory limit of 30 thousand.

Be aware of the risk of injury from high voltage traveling through the wires leading from the coil to the spark plug tips. An important element of the spark plug is replacing them, so it must be done carefully.

CHAMPION RN9YC

Price: from 280 rubles.

CHAMPION RN9YC is a mid-range spark plug that is easy to install in your engine. The element fits firmly into a standard seat and allows you to maintain engine operation at the required parameters for a long time. Spark plugs wear out slowly and can serve faithfully for several years without any problems. Moreover, this applies even to those cases when operation is carried out in difficult conditions.

Pros:

unpretentiousness to operating conditions;
durability;
ease of installation into the engine;
ensure uniform and stable combustion.

Minuses:

high price;
It does not work very stable with some engine models.

What is the algorithm in the operation of the ignition unit?

By means of spark plug electrodes, a spark is generated in the combustion chamber, which allows the mixture to ignite. The operation of these components involves harsh conditions involving exposure to very high thermal and electrical loads. The temperature indicator of the spark plug electrodes of working spark plugs can reach 900 degrees. In the Lada Granta ignition system, the spark plug arc discharge, which generates a spark, is characterized by a potential of 30 - 40 kV.

The severity of the operating mode of these elements directly affects the resource. Also very common is the appearance of carbon deposits on electrode surfaces, which is caused by disturbances in the combustion process.

We should not forget an important point related to the detrimental effect of unit overheating on the life of most components of the ignition circuit. It is candles that are subject to increased requirements in terms of ensuring the ability to function under conditions of increased thermal disturbances.

The stability of spark production at the electrodes indicates the normal functioning of both the spark plugs themselves and other components of the ignition unit. To ensure trouble-free operation of system components, the following postulates should be strictly observed:

Trunk size of Lada Granta liftback
Grant's trunk

spark plugs are replaced only with those consumables that are approved by the regulatory requirements of AvtoVAZ;
