What is carbon deposition (Dieselpartsworld) 2016-01-17   

Carbon accumulation is in the engine combustion chamber, and sometimes due to inadequate supply of oxygen, fuel combustion is not complete, resulting in the phenomenon of soot. Leave the oil, dust, and other debris engine when working for a long time of sludge. The cylinder oil generally referred to as "coke".
At the same time, the amount of oxygen supply is not sufficient, channeling into the combustion chamber of the lubricating oil can not be completely burned, resulting in the burning of oil particles.
A large number of mixed combustion lubricating oil residue and soot is oxidized into a colloidal liquid light amino acids in the engine.
The further oxidation of the light base acid turns to be a kind of tree vinegar resin and firmly adhere to the surface of the engine parts.
Then under the condition of high temperature, colloid and further polymerization into more complex polymer into hard cemented carbon, commonly known as coke.
