In the life of every motorist comes suchthe moment when his car does not want to start. It happens, he still gives some signs of life, but, often, he just is silent and rotates with a starter, resulting in a dead state and the battery. Then should hold a series of activities.
To ignite the mixture in the combustion chambertwo things are required: the mixture itself and the spark that will ignite it. First of all, in such cases it is worth making sure that the first one is available. If everything is fine with her, then you need to unscrew the candles and make sure that the second one is available.
In addition, you must ensure that the electrodes are clean andfind out if there is soot on the candles. The color of the spark plugs in such situations may suggest the origin of the malfunction. Of course, you need a certain skill to determine the shade, but it all comes down to the practice and examination of candles in different situations.
For example, black soot on candles thatthey are cleaned only with coarse sandpaper, it says that oil gets into the cylinders, which means it's time to think about replacing it, together with piston rings and oil scraper caps. As a rule, this symptom is accompanied by increased engine opacity, as well as a sharp drop in power. The first is most pronounced during start-up and starting off, because at such times the most combustible mixture gets into the cylinders.
Черный нагар на свечах зажигания, который rubbed with a finger or a rag, is a consequence of over-enrichment of the mixture, it is just soot. It is logical to assume that in addition to this, the driver should notice an increase in fuel consumption. If the car owner himself does not notice, then he should be shown this at the next technical inspection, since the concentration of harmful emissions increases significantly. Also, a clue can serve as black smoke from the exhaust pipe, which appears quite rarely. In general, the color of the exhaust gases and the color of the spark plugs are directly related, since the former are deposited on the second, and this is used by experienced motorists and car repairmen.
In addition, the soot on candles can be white orwith a shade of gray. This color indicates that there is not enough gas in the combustible mixture, it is depleted. To eliminate this problem, it is worth adjusting the carburetor a little, or checking the operability of the control unit. Like all the other symptoms, this one is not left alone, as they say “there is no smoke without fire,” only here it is the opposite. Besides the fact that there is soot on the candles, there are also clouds of smoke of the same color, which are especially evident during heavy loads on the engine. Starting is also difficult, it only happens after 20-30 seconds of crankshaft rotation by the starter. The thing is that there is not enough gas in the mixture to ignite.
So what should be the candles? RedheadsThis answer may confuse many car owners, but it is. The color should be sandy. An important condition is the cleanliness of the electrodes. It is worth paying attention to the above symptoms with each replacement of candles, this will help to prolong the engine's life.
