How often or how many kilometers do you clean up the carbon deposits in the combustion chamber?

Generally, the carbon deposit in the combustion chamber is cleaned once every 2 years or 4 weeks.

When the car runs for a long time, the carbon deposits in the air intake, valve and combustion chamber will increase. These carbon deposits will adsorb fuel when the car is cold and release fuel when it is hot, which will lead to the phenomenon that the car is not easy to cool down and the fuel consumption is high when it is hot, which will lead to poor engine performance, idling jitter, poor acceleration, increased fuel consumption and excessive exhaust gas. Therefore, cleaning the carbon deposit in the combustion chamber can reduce the occurrence of the above faults.
