How to Clean Carbon Deposits in Car Engine?
2 Answers
Here are the methods to clean carbon deposits in a car engine: 1. Disassemble the engine and use cleaning agents or ultrasonic methods to thoroughly remove carbon deposits from the components. This process requires significant time and effort. 2. Machine Cleaning: Inject a cleaning agent into a machine, then pressurize it into the combustion chamber to allow the cleaning agent to react with and dissolve the carbon deposits. The waste liquid is then extracted. This method is effective for severe carbon buildup and does not require engine disassembly, but it is more expensive, and the engine oil needs to be replaced after cleaning.
My old car used to have severe carbon buildup in the engine, causing frequent shaking and increased fuel consumption. I've tried many methods to clean it. The most common one is adding fuel additives—just pour them directly into the fuel tank, and running at high RPMs on the highway can effectively break down the carbon deposits. I regularly use well-reviewed cleaners, like adding them every 5,000 kilometers, but don’t overdo it, as it can harm the engine. Carbon buildup is mainly caused by incomplete combustion, so prevention is key: choose high-quality fuel, avoid frequent short trips with idle time, and take a highway drive once a month to clear deposits. If the problem gets serious, you may need to disassemble the engine for manual cleaning or use professional equipment, but for most household cars, these small daily actions can keep things running smoothly. Cleaning carbon deposits not only saves fuel but also extends engine life—don’t ignore it, or repairs can become a real hassle.
