Surely every car enthusiast thought about how the engine of the internal combustion of his car works. In this article, you will not know about all its work, but only a small but very important item, is the spark plugs. To enormous regret, these details are short-lived and they have to be cleaned over time or change completely.
So, the spark plugs are designed to serve as a spark in the fuel and air mixture. And after a certain time on their surfaces, a flight (Nagar) is formed. In some cases, you can return the candle, just considering this flask, but there are moments in which you have nothing to help the candles and their place in the landfill.
The diagnosis of spark plugs should be carried out in a certain order.
How often change spark plugs - visual inspection
We remove the contacts and unscrew the candles with a special candle wrench from the head of the cylinder block. We visually inspect every candle for Nagara. In thickness and color, you can determine whether the candle comes to operate in the future or not. If the tint of Nagar has a yellowish or brownish color, then it is not worth worrying. Because these shades are allowed when the candles are working. If the nagar layer is very thick and has a shade of black, then it is already worth thinking and make a detailed cleaning or replacement of all candles.
How often can change spark plugs - cleaning candles
If you still decide to clean the candles from Nagar, then you should start with a total cleaning from dirt and dust. To do this, all removed candles are lowered into the solution and leave for a while, and later brushing the tassel. After a few of these cleaning on the candle shell, scratches and cracks appear, which lead to deposit in the future of strong Nagar.
How often to change spark plugs - gaps
- According to maintenance data, the gap between the contacts of the ignition candle should be in the range from 0.5 to 0.6 mm. This work is done using special amplifying probe, each of which has its own thickness in mm. Naturally, when the engine is running, the gap will increase due to contacting contacts. Spark will not appear immediately and increase fuel consumption. It is possible to reduce the gap quickly, begging the top contact using the key.
- At maintenance stations, can conduct diagnostics of candles without removing them with special equipment. It tests every spark plug and measures the scope formation time. If malfunctions are found, the device will definitely show this information by a specialist, which in turn will clean or replace all faulty candles.
The replacement of candles in a compulsory manual card is made after every 30 thousand km. It is worth noting that in the winter period, the diagnosis of candles should be carried out much more often than in the summer.
