How to Remove Carbon Deposits?
2 Answers
Clearing carbon deposits is a relatively effective method using walnut shell blasting. Here is relevant information about carbon deposits: 1. Intake system: Every engine will have carbon deposits. It is very normal for carbon deposits to appear inside the engine after prolonged use. Car owners only need to periodically remove the carbon deposits. Carbon deposits are quite harmful to the engine. If carbon deposits are on the intake system, it will cause incorrect air intake volume, leading to an incorrect air-fuel ratio. If the air-fuel ratio is incorrect, it will affect the engine's power output and fuel consumption. 2. Combustion chamber: If carbon deposits are in the combustion chamber, it will increase the compression ratio of the combustion chamber, causing engine knocking. Knocking will affect the engine's power output and fuel consumption, and it can also damage the engine.
I can share my experience in removing carbon deposits, after all, I've been driving for over a decade. Carbon buildup can make the car feel sluggish, increase fuel consumption, and affect performance. The easiest method is regular highway driving: find some free time, drive on the national highway at a speed of 80-100 km/h for half an hour. The high temperature can burn off surface carbon deposits, and it's free! Another method is using fuel additives, such as Bosch or 3M products available on the market. Just add one can to the fuel tank when refueling; doing this monthly can dissolve carbon deposits. Choose products containing polyetheramine for better results, but avoid excessive use. If the engine shakes or the warning light comes on, deeper cleaning is needed: you can buy throttle body cleaner spray, remove the air filter, spray and wipe gently to avoid damaging the wiring. For severe cases, seek professional services like walnut shell blasting at a repair shop—it costs a couple hundred but cleans thoroughly. To prevent carbon buildup: avoid prolonged idling and sudden braking; change the engine oil regularly and use OBD diagnostics to check for error codes. Combining DIY and professional solutions will restore smooth engine performance, improve fuel efficiency, and ensure safety.
