What are the methods for cleaning carbon deposits in an engine?

[MacAaliyah]

Methods for cleaning carbon deposits in an engine include: 1. "Drip cleaning": A high-pressure atomized cleaning agent is placed in a bottle and injected into the intake valves, fuel injectors, spark plugs, intake pipes, etc. The cleaning agent decomposes the carbon deposits, which are then expelled by running the engine at high RPM. 2. Directly spraying carburetor cleaner into the engine's combustion chamber, where the cleaner causes the carbon deposits to re-burn and turn into liquid, which is then expelled. 3. Disassembly cleaning, which is a very thorough method and can clean vehicles with severe carbon deposits very effectively. Carbon deposits mainly form due to incomplete combustion of fuel in the engine or unburned paraffin and gum substances in gasoline, which remain in components such as fuel injectors, throttle bodies, fuel lines, and spark plugs. Under high temperatures, these substances turn into carbon deposits. Over time, the accumulation of carbon deposits can cause engine components to malfunction, leading to issues such as difficulty starting, unstable idling, reduced power, and sluggish acceleration.
