After how much you need to change the candles

Automotors have a part of the question, after how much you need to change the candles. Among the masters there is a concept about the period of replacement of spark plugs. It is worth remembering that each case is unique and all individually.

Some cars have enough new candles only by 10,000 km, while others ride them to 100,000 km. To figure out what a paradox should be understood from which the life of the candle may depend on.

Of course, first of all, the term of work depends on the quality of the candles themselves and from the manufacturer. Spark plugs are the following types:

Iridium;
Platinum;
Ordinary;

By design, the candles are installed inside the engine, so they cannot be viewed without extraction.

Why do candles need

Let's remember what purpose candles are needed in the engine. They are needed to use the spark to adjust the fuel-air mixture, which burns in the cylinder of the power unit. The mixture is lit with an electrical charge of several thousand volts, which appears between the electrodes in the candle.

In the diagram below you can see from which components the spark plug consists.

Contact pin - the high-voltage wires of the ignition system are connected here;
Isolator - protects the candle from overheating and has a serious impact on the quality of the candle;
Isolator's ribs - serve to prevent electrical breakdowns on the surface;
The central and side electrode - the spark appears between them, which ignites the fuel and air mixture in the cylinder;
Sealer - does not miss hot gases from the combustion chamber;

An important indicator is the gap between the central and side electrode. It is from them that it depends on how effective the mixture will be in the cylinder. The greater the gap, the more large-scale and powerful will be the zone of ignition. With a good gap, the fuel is perfectly burning, which gives the smooth operation of the engine.

When changing spark plugs

Regular visit to the STR takes place every 10 - 15,000 km. At the same time, it is recommended to change the spark plugs. Car manufacturers imply that the car owner uses original candles, so if you put yourself ordinary candles, change them more often.

If you do not attend regular a hundred, then you can unscrew the candles once every 15,000 km and check what their degree of wear. Candles can quickly fail at one machine, and, on the contrary, working for a long time on another car. If you have, then the native candles will go for a long time. Try to buy candles of similar quality so that they can work several tens of thousands of kilometers.

One of the main reasons for the rapid failure is to use low-quality fuel. It is no secret that most of the refueling are fighting for a place under the sky, so they try to reduce the price of fuel by adding different additives into it. This moment has a negative impact on the operating characteristics of the motor. Conclusion: refuel on proven gas stations - the smaller the likelrost is to buy low-quality fuel.

How to determine the state of spark plugs

When candles are worn out, the first thing that comes to the eye is the engine begins to trim. Other vibrations, noises and unstable turns begin to appear. Before contacting a hundred, you can save money and try to determine the condition of the candles.

First, determine the gap between the electrodes, their size and level of Nagara. Find out what the sizes of the electrodes should be from your grade candles, you can from the instruction. If a big gap, then the candle has already worked out and need to be replaced.

Ideal when there is no Nagar at all. If it is, it means that the fuel burns not as needed. Also look, in what condition are ceramic insulators. They should not have cracks and defects.

Other reasons for which it is worth replacing the spark plugs, look in the video.

If during inspection you have detected damage, replace the candle, and it is best to replace the entire kit. So you will make the engine work more stable. Also, the frequency of replacement of candles depends on their type. Platinum and iridium ignition candles can work flawless up to 80,000 km. The usual works only 10 - 20,000 km of run.
