Causes and elimination methods of engine carbon deposition
  • Automotive

Carbon deposition is the product of fuel and lubricating oil under high temperature and oxidation. In the combustion chamber, because of the lack of oxygen supply during the combustion, the fuel and the lubricating oil that flee into the combustion chamber can not be completely burned, producing particles of oil smoke and burning oil, forming hard cemented carbon under the action of high temperature and oxidation, commonly known as carbon deposition. Carbon deposits have volatile substances (oil, base acids) and non volatile substances (asphaltene, oil coke, carbon green and ash). The more volatile matter is not easy to volatilize, the harder the carbon is, the stronger the bond and the stronger the bond with the metal.
