Why Does The Car Have Carbon Deposits?

Sep. 25, 2018

What is carbon deposit? The Toyota Cylinder Head Manufacturer simply explains: carbon deposit refers to the colloid (the main component is hydroxy acid, asphaltene, refueling, etc.) produced when the fuel and the lubricating oil strung into the combustion chamber cannot be completely burned, so as to adhere to the inlet/discharge. The valve, the cylinder edge, the top of the piston, the spark plug, and the combustion chamber are continuously accumulated under the action of the engine's repeated high temperature, which accumulates the formed hard cement carbon, that is, carbon deposit. The reason for the formation of carbon deposit: Although the engine technology is quite advanced, the efficiency of the combustion chamber is only 25%--30%. Therefore, the carbon deposit is mainly caused by the phenomenon of the machine itself, and the poor quality of the gasoline. Generally, the quality of gasoline produced by refineries may vary, so the degree of impact is slightly different, but if solvent oil or illegal oil is used, it will lead to more serious carbon deposits.

After the car has been running for a while, the fuel system will form a certain deposit. The formation of sediments is directly related to the fuel oil of automobiles: firstly, because gasoline itself contains colloids, impurities, or dust and impurities brought in during storage and transportation, it forms a sludge-like deposit in the fuel tank and oil inlet pipe. Secondly, the unstable components such as olefins in gasoline undergo oxidation and polymerization at a certain temperature to form a colloidal and resinous viscous material. These viscous deposits become hard carbon deposits in the fuel injectors, intake valves, combustion chambers, (Toyota 4Y Cylinder Head and few tops). In addition, due to urban traffic congestion, cars are often at low speeds and idle speeds, which will increase the formation and accumulation of these deposits.
