Carbon deposits on pistons form quite naturally. In general it is not a problem if the oil and fuel consumption does not increase, the power of the engine does not decrease, ignition and detonation occur as it should. It is necessary to remove soot, but if the car is in good order, you will not have to do it too often. Except that sometimes soot on cylinders is formed at some incredible rate and in quantities. It happens that already at 20 thousand km of run, the engine starts having problems due to contamination of pistons. What can be the cause of such misfortune?
Reason One: Gasoline
One of the most popular reasons for the rapid formation of carbon deposits on engine pistons is low-quality gasoline with malignant impurities. More often than not, such appears in the car after refueling at an untested gas station. Usage of low-quality fuel is fraught with not only abundant soot formation, but many other problems. You can easily get problems with fuel equipment. There is only one way to protect yourself from “dirty petrol” (or diesel) – to fill up your tank in proven locations. There is no need to economize at gas stations. Remember that a miser always pays twice.
The second reason: driving style
If you understand it thoroughly, it quickly becomes clear that the economical driving style is not so economical as it may seem at first sight. Do you abuse the switching on high gear at the first opportunity in hope to save fuel? You will have to pay for calm “pensioner” driving with a great quantity of soot and deposits on pistons of the engine. It occurs because the power unit hardly ever works in a limit mode while such driving. In this mode, the engine sucks crankcase gases, which in turn contain a huge amount of oil vapor.
Reason three: Oil
Another cause of increased formation of soot and carbon monoxide, which should not be forgotten in any case is car oil. Remember that up to 80% of soot is just unburned products from oil composition. However, even high quality expensive lubricant is not a panacea in this case. With time it also starts to accumulate dust, soot, bitumen and wear products. How to get out of such a situation? In fact, it is very easy – it is enough to regularly and timely replace the engine lubricant.
