How to clean up the carbon deposit in 12 Tianzhu?

Why is carbon deposition produced? This is because the fuel itself contains colloid, impurities, dust, moisture and so on. And deposits such as sludge are formed in the fuel tank and the oil inlet pipe over time; Secondly, unstable components such as olefins in gasoline undergo oxidative polymerization at high temperature, forming mucilage and resinous viscous substances, which stay in fuel nozzles, intake valves and other parts, and the deposits will become hard carbon deposits during combustion.

In addition, traffic jams often make cars idle at low speed, which will aggravate the formation and aggravation of carbon deposits and sediments. If the carbon deposit is not cleaned up in time, the carbon deposit and deposits will block the needle valve and valve hole of the injector, which will lead to irregular closing of the intake valve, decreased cylinder pressure and even backfire, which will lead to unstable idle speed of the engine, increased fuel consumption and deteriorated exhaust emissions. Carbon deposition on the piston top and cylinder head can easily lead to local overheating and gasoline preheating in the combustion chamber, which may lead to engine knocking and other failures. These faults will shorten the service life of the engine.

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.
