What can tell candle on candles

In the life of every car enthusiast comes a time when his car does not want to start. Sometimes, he still gives some signs of life, but, often, he just keeps silent and rotates the starter, bringing the dead state and battery. Then a number of measures should be taken.

To ignite the mixture in the combustion chamber, two things are required: the mixture itself and the spark that will ignite it. First of all, in such cases it is necessary to make sure the presence of the first. If it's all right, then you need to unscrew the candles and make sure there's a second one.

In addition, you need to make sure of the cleanliness of the electrodes and find out if there is candle on the candles. The color of the spark plugs in such situations may indicate the origin of the malfunction. Of course, you need a certain skill to determine the shade, but it all comes down to practice and examining the candles in different situations.

For example, black candle on candles, which are cleaned only with coarse-grained emery paper, indicates that the oil gets into the cylinders, which means it's time to think about replacing it, together with the piston rings and oil-sealed caps. As a rule, such a symptom is accompanied by increased smoke of the engine, as well as a sharp drop in power. The first is most evident during start-up and moving from the spot, because at such times the most combustible mixture gets into the cylinders.

The black carbon on the spark plugs, which is rubbed off with a finger or rag, is a consequence of the mixture's over-enrichment, it's just soot. It is logical to assume that in addition to this, the driver should notice an increase in fuel consumption. If the owner of the car does not notice, then he should be pointed to this at the next inspection, as the concentration of harmful emissions significantly increases. Also a clue can serve as black smoke from the exhaust pipe, which is quite rare. Generally, the color of the exhaust gases and the color of the spark plugs are directly related, since the first are deposited on the second, this is what seasoned car enthusiasts and car service masters use.

In addition, the candle burn can be white or with a shade of gray. This color indicates that there is not enough gasoline in the fuel mixture, it is depleted. To eliminate this problem, it is necessary to adjust the carburetor a little, or to check the serviceability of the control unit. Like all other symptoms, this one does not remain alone, as they say "there is no smoke without fire", only here everything is the other way around. In addition to the fact that there is a candle on the candles, there are also smoke clouds of the same color that are especially evident during heavy loads on the engine. It is also difficult to start, it only occurs after 20-30 seconds of crankshaft rotation by a starter. All the matter is that for ignition in a mix there is no enough gasoline.

So what should be the candles? Redheads. This answer may confuse many car owners, but it is so. The color should be sand. An important condition is the purity of the electrodes. On the above symptoms should pay attention to every replacement of candles, this will help extend the life of the engine.
