Is Combustion Chamber Cleaning at 4S Stores Necessary?
1 Answers
Combustion chamber cleaning at 4S stores is actually unnecessary, as stubborn carbon deposits cannot be removed through this method, while minor carbon deposits can be cleaned simply by driving on the highway. Below is relevant information about cleaning carbon deposits in car engines: Carburetor cleaning: Remove the throttle body, clean both sides with carburetor cleaner, and wipe dry with a cloth. It is generally recommended to clean the throttle body once a year or every 20,000 kilometers, though different vehicle models may have varying cleaning cycles, so refer to the maintenance manual. Carbon deposit cleaners: Internal engine carbon deposit cleaning can be done before changing the oil. Open the oil cap, add the cleaner, mix it with the old oil, and let the engine idle for about 10 minutes. Intake system cleaning: For intake system cleaning, purchase a bottle of intake system cleaner, pour it into the reservoir of a dedicated cleaning device, connect it to the intake system, and start the engine to use vacuum to draw the cleaner into the intake passages for cleaning purposes.
