How to Clean Carbon Deposits in Engine Cylinders?

Cleaning carbon deposits in engine cylinders can be done using the walnut shell blasting method. The walnut shell blasting method involves grinding walnut shells into powder and then using a specialized machine to blast the walnut shell particles, which can remove carbon deposits from the engine. It is recommended to seek professional services at specialized institutions. More relevant information is as follows: 1. It is normal for carbon deposits to form inside a car's engine after prolonged use because the combustible mixture in the engine cannot burn completely and thoroughly. Over time, carbon deposits will accumulate in the engine. Carbon deposits can affect the engine's performance, so it is advisable for car owners to clean them regularly. 2. Fuel additives can remove some carbon deposits and help reduce their formation. However, fuel additives cannot completely eliminate carbon deposits, and only genuine fuel additives from reputable brands have the effect of removing carbon deposits. Inferior fuel additives may damage the engine and do not have the effect of cleaning carbon deposits.

There are various methods to clean carbon deposits in the engine cylinders. My car has been running for several years, and unstable idle speed was found to be caused by carbon buildup. The simplest way is to buy a bottle of fuel system cleaner, add it to the fuel tank, and then drive on the highway for about a hundred kilometers at high RPM to burn off the deposits. Carbon deposits often form due to unclean fuel or too much short-distance driving. Regular use of such additives can help prevent buildup. I've used it several times with good results—the engine runs smoother, and fuel consumption has slightly decreased. Make sure to choose a cleaner suitable for your engine to avoid corrosion. Using high-quality fuel can also reduce carbon deposit formation, but never attempt to disassemble the engine yourself—it's too dangerous.

I love working on my own car, and cleaning carbon deposits by hand is quite satisfying. Grab a toolbox, remove the spark plugs, spray the intake system with throttle cleaner, and use a soft cloth to wipe away stubborn residues. Carbon buildup can make the vehicle hard to start—addressing it early saves big money. It's recommended to use a professional cleaning kit and wear gloves to avoid skin corrosion. The process requires patience; doing it every 20,000 kilometers is the most effective prevention. Also, check if the fuel filter is clogged, as it can lead to incomplete combustion. DIY saves a lot compared to going to a shop, but be careful not to damage seals or wiring. After DIY, the engine responds much faster, feeling like it’s restored to its original performance.

For long-term handling of such issues, professional cleaning services are recommended as a priority. Carbon deposits may obstruct airflow and affect performance; using intake manifold cleaning equipment or sandblasting methods can achieve a thorough clean in one go. Such operations require safety tools to avoid fire hazards, as solvents are flammable and explosive. Regular oil changes and maintenance with standard parts are essential to reduce metal impurities that cause carbon buildup. Improper engine disassembly can damage gaskets, so avoid attempting it casually. Professional technicians use diagnostic tools to quickly and reliably locate issues, ensuring high efficiency. Post-cleaning, emissions can be significantly reduced, fuel consumption lowered, and machine lifespan extended. Prices generally range from one to two hundred yuan, making it a worthwhile investment.
