How to prevent the Ford Ids Vcm engine carbon deposits
Coke is produced after the blow-by gas of the fuel and lubricant mixed incomplete combustion deposits. (Main ingredient is a hydroxy acid, asphaltenes, tars, etc.) and the formation of deposits and cars "fuel" and "lubricating oil" is directly related to: the first is due to the "lubricants" blow-by gas contained in the carbon particles, in the incomplete burning a lot more deposition.
The car itself contain pectin, impurities, or the storage and transportation process into the dust, impurities, etc., accumulate in the vehicle tank inlet pipe and other parts of the formation of sludge-like sediment; Secondly, due to the the gasoline olefin unstable group copies certain temperature, oxidation and polymerization, the formation of gum and resin-like viscous material. These viscous material in the nozzle, intake valve and combustion chamber (cylinder head and the piston top) and other parts of deposition becomes hard carbon deposits. In addition, due to the urban traffic congestion, the car often at low speed and idling state, but also will increase the formation and accumulation of these sediments.
Japanese and Korean models probably 30000KM should be cleared once a low rpm high torque engines, because the majority of the open type of Japan and South Korea for the emphasis on lower revolutions Driving, carbon deposits on engine power and fuel consumption impact is relatively small. In contrast, Europe and the United States Department of models probably 20000KM should want to clear the time, Europe and the United States Department of the models most in high-speed engine reaches a certain speed into the real power output, mostly in high-speed driving, high speed, tried out the low-speed coke engine is reflected in the low-speed acceleration is more obvious.
