How to Clean Carbon Deposits in Cars?
2 Answers
Methods for cleaning carbon deposits in cars: 1. Engine disassembly and cleaning, which requires removing the engine and thoroughly cleaning carbon deposits from components using detergents, ultrasonic methods, etc.; 2. Using an engine cleaning kit, where a bottle-shaped tool is suspended above the engine, and cleaning agents are poured into the tool and introduced into the engine through a tube to clean carbon deposits. Methods to reduce carbon deposit formation: 1. Use high-quality fuel, as the main components of carbon deposits are wax and gum deposits from fuel, so the lower the gum content in the fuel, the better; 2. Avoid prolonged driving at low RPMs and periodically drive at high speeds. The principle behind high-speed driving to remove carbon deposits is to accelerate gas flow, which can remove a small portion of loosely attached carbon deposits, increase combustion temperature, and burn off some carbon deposits in the cylinders.
I've been driving for many years and have seen plenty of carbon buildup issues. There are several cleaning methods: first, use fuel additives—add a bottle each time you refuel, and drive a few hundred kilometers to clean carbon deposits from the fuel system and injectors. It's convenient and cost-effective. For severe carbon buildup, it's recommended to go to a professional shop for an IV cleaning or manual engine disassembly and scraping—though time-consuming, the results are thorough. Prevention is key: drive more on highways to let the engine burn off carbon deposits at high temperatures, and use high-quality gasoline and full synthetic oil to reduce carbon buildup. Don’t underestimate it—carbon buildup not only increases fuel consumption but can also cause engine misfires and excessive emissions. It's advised to check every 20,000 km and address it early to avoid major repairs.
