How is carbon deposition formed? What is carbon deposition?

Carbon deposition refers to the colloidal substance similar to sludge produced when the fuel and engine oil vapor escaping into the combustion chamber cannot be completely burned. These substances are attached to almost any part of the engine room, including intake valve, exhaust valve, spark plug, oil nozzle, piston top and so on. After continuous accumulation and repeated high temperature of the engine, carbon deposit similar to coal is finally formed.

How to judge automobile organic carbon? It can be judged that the car carbon deposit is serious when the car has the following conditions:

1, the cold car is not easy to start after repeated ignition, and it is normal when it is hot;

2, the engine idle speed is unstable, and the speed is high and low;

3, driving feels weak and sultry, especially when overtaking, the speed response is slow, which is very different from the new car;

4. The automobile exhaust is pungent and the emission exceeds the standard;

The fuel consumption of cars is much higher than before.

How to clean up the car carbon deposit?

Commonly used methods are: disassembly and washing, bottle washing 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. Effective fuel additives, such as PNF stock solution, are non-corrosive, will not block ternary, and have high safety.
