How to deal with carbon deposit

The method of carbon deposition treatment is as follows:

1, automobile infusion bottle. Hang a bottle-shaped tool above the engine, then pour the cleaning agent into the bottle-shaped tool and introduce it into the engine through the conduit to clean the carbon deposit. The price is around 1000 yuan. If the engine has serious carbon deposition, this method will lead to blockage or damage of the three-way catalytic system.

2. Machine wash. Inject the cleaning agent into a machine, then press it into the combustion chamber with the machine, let the cleaning agent react with the carbon deposit to dissolve, and then pump out the waste liquid. This method has a good effect on some serious carbon deposits, and it is not necessary to disassemble the engine, but the cost is high and the oil needs to be changed after cleaning.
