How to Clean Excessive Carbon Deposits in Cars?
2 Answers
There are several methods to clean carbon deposits in cars: 1. Engine disassembly cleaning: In terms of effectiveness, engine disassembly cleaning is undoubtedly the most effective method for removing carbon deposits. However, the entire process requires a significant amount of time and effort. The engine needs to be disassembled, and then cleaning agents, ultrasonic methods, etc., are used to completely and thoroughly remove carbon deposits from the components. Of course, it is also the most expensive option. 2. Intravenous cleaning: A bottle-shaped tool is hung above the engine, and cleaning agents are poured into the bottle. The cleaning agents are then introduced 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 the three-way catalytic system to become clogged or damaged. 3. Machine cleaning: Cleaning agents are injected into a machine, which then pressurizes the agents into the combustion chamber. The cleaning agents react with and dissolve the carbon deposits, and the waste liquid is then extracted. This method has a relatively good effect on some severe carbon deposits and does not require engine disassembly. However, it is relatively expensive, and the engine oil needs to be replaced after cleaning.
Last time my car had weak acceleration, and upon inspection, it turned out to be excessive carbon buildup. As an experienced driver, I've tried several methods: the simplest is using fuel system cleaner, adding it to the fuel tank and driving at high speeds, which burns off the carbon deposits through combustion. However, avoid cheap brands as they might corrode the engine. If the situation is severe, you'll need to go to a repair shop to remove and clean the throttle body and fuel injectors. I had this done once at a 4S shop, costing a few hundred yuan, and the power noticeably recovered. For prevention, avoid idling too long in congested areas and use higher-grade gasoline to reduce carbon buildup. Regular maintenance is crucial; checking related components during oil changes can help detect issues early. In short, clean carbon deposits promptly to avoid bigger problems.
