How to Remove Carbon Deposits?
2 Answers
Methods for removing carbon deposits in a car are as follows: 1. "Drip Cleaning" for the car. Hang a bottle-shaped tool above the engine, pour the cleaning agent into the bottle-shaped tool, and then introduce it into the engine through a conduit to achieve the purpose of cleaning carbon deposits. However, if the engine has severe carbon deposits, this method may cause blockage or damage to the three-way catalytic system. 2. Machine Cleaning. Inject the cleaning agent into a machine, then pressurize it into the combustion chamber using the machine to allow the cleaning agent to react with and dissolve the carbon deposits, and then extract the waste liquid. This method is more effective for some 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.
As a veteran driver with 20 years of experience, I have my own traditional methods for cleaning carbon deposits. The easiest way is to regularly use fuel additives—just pour a bottle into the tank before refueling, and running on the highway yields the best results. I've tried several brands, and those with polyetheramine ingredients have stronger cleaning power. For cars frequently driven in urban areas, it's best to use it every 5,000 kilometers to prevent fuel injector clogging. Cleaning the throttle body is also crucial. I keep carburetor cleaner on hand, spray it after disassembling the throttle body, and wipe off the layer of black sludge—the throttle response immediately feels lighter. If the engine is already shaking badly, walnut shell blasting for intake cleaning at a repair shop is the most thorough solution, though it costs a few hundred bucks.
