How to clean up engine carbon deposit?

Commonly used methods are: disassembling and washing, clearing infusion bottles and fuel additives.

1, disassembly and cleaning

This method is very direct and rude, but it is usually sent to 4s stores. Disassembly of the engine is complicated. No matter what parts are disassembled every time, their performance will be more or less affected. Need to hire a professional master to disassemble. Dismantling and washing can directly see the carbon deposit in the engine, and the cleaning will be cleaner. But the cost will be higher and technology will be needed.

2, infusion bag or infusion bottle cleaning

This method is also quite common. When the cleaning agent is discharged into the air inlet, the carbon deposit is diluted and softened into slurry, and then burned and discharged from the cylinder. General cleaning objects include air intake, throttle valve, intake valve, oil nozzle, cylinder interior and so on. , but the effect is not as obvious as unpacking and washing.

3. Fuel additives

One reason for carbon deposition is that the fuel is not completely burned and adheres to various parts of the engine, and carbon deposition is formed over time. The main function of additives is to drill into the pores of carbon deposits with strong surface activity, destroy its structure, gradually dissolve these carbon deposits from the metal surface, then burn them with fuel at high temperature, and then discharge them through waste gas. In fact, the effect of this magical additive is not obvious.
