Carbon Deposition- There are some hydrocarbon olefin residues attach on engine intake, cylinder when fuel burn in engine not completely. These residues change into hard black shell in high temperature condition , that called carbon deposition. Carbon deposition will decrease air-fuel ratio, cut down engine output power, increase fuel consumption, engine drastic shake on idle status...all the thing will hurt engine deeply. So normally we should clean carbon deposition after every 40000-50000 KM.
