How Often Should Carbon Deposits in the Engine Be Cleaned?

[Chloe]

Generally, 4S shops recommend car owners to perform maintenance every 10,000 kilometers. Here are some methods for cleaning carbon deposits in the engine: Engine Drip Cleaning: A bottle-shaped tool is hung above the engine, and the cleaning agent is poured into the bottle. It is then introduced into the engine through a tube to clean the carbon deposits. If the engine has severe carbon deposits, this method may cause blockage or damage to the three-way catalytic system. Machine Cleaning: The cleaning agent is injected into a machine, pressurized, and sprayed into the combustion chamber. The cleaning agent reacts with and dissolves the carbon deposits, and the waste liquid is then extracted. This method is quite effective for severe carbon deposits and does not require disassembling the engine, but it is more expensive, and the engine oil needs to be replaced after cleaning. Engine Disassembly Cleaning: This method is likely the most effective. The entire engine is disassembled, and cleaning agents, ultrasonic methods, etc., are used to completely and thoroughly remove carbon deposits from the components.
