How to Clean Carbon Deposits in Cars Thoroughly?
1 Answers
Methods for cleaning carbon deposits in cars are as follows: 1. Regular maintenance and cleaning. If possible, during routine car maintenance, use specialized cleaning equipment to perform non-disassembly cleaning on parts prone to carbon deposits, such as the intake manifold and oil passages. 2. Use higher-grade gasoline whenever possible. The wax and gum impurities in gasoline are the main components that form engine carbon deposits. In other words, gasoline with higher cleanliness tends to form less carbon deposits. Higher-grade gasoline has a higher octane rating compared to lower-grade gasoline, burns more completely and cleanly, thus significantly reducing the likelihood of carbon deposit formation. 3. Use appropriate gasoline additives. You can use gasoline additives from reputable brands with good after-sales service or those specified by the car manufacturer. Common gasoline additives on the market are generally divided into two types: one is maintenance-type gasoline additives that primarily aid combustion, and the other is cleaning-type gasoline additives that mainly remove carbon deposits. Be careful not to mix different brands or types of gasoline additives with different functions, and follow the instructions on the product label for the correct usage. 4. Try to increase shift RPM and occasionally drive at high speeds. Shifting at higher RPMs and driving at high speeds both utilize large amounts of air intake to flush the intake passages, preventing and reducing carbon deposit buildup while improving the car's performance. Generally, it is recommended to shift between 2500 to 3000 RPM. 5. Avoid prolonged idling. Frequent idling can easily lead to carbon deposit formation, and insufficient air intake can further promote carbon deposit buildup. For turbocharged engines, the likelihood of carbon deposit formation is higher than that of naturally aspirated vehicles. Therefore, after high-speed driving or climbing, do not turn off the engine immediately; instead, let it idle for about 10 minutes to avoid carbon deposits.
