Methods for Cleaning Carbon Deposits Inside Engine Cylinders
2 Answers
Engine cylinder carbon deposit cleaning methods are as follows: 1. For internal engine carbon cleaning, before replacing the engine oil, open the oil filler cap, add cleaning agent, mix it with the old oil, and let the engine idle for about 10 minutes. 2. Cleaning carbon deposits in the intake system mainly refers to cleaning carbon deposits inside the intake manifold and other components. The purpose is to remove carbon deposits inside the intake system, increase intake flow and speed, and reduce engine shaking and unstable idling. Prepare intake system cleaner, use a dedicated cleaning device's liquid storage tank, connect it to the intake system, and use vacuum to draw the cleaner into the intake passages to achieve the cleaning purpose. 3. Remove the throttle body, use carburetor cleaner to clean both sides of the throttle body, and wipe it dry with a clean cloth. It is recommended to clean the throttle body after one year of use or after driving 20,000 kilometers. However, it should be noted that different vehicle models may have different cleaning cycles, which should be determined based on the specific condition of the vehicle.
The most commonly used method for cleaning carbon deposits inside the engine cylinders is fuel additives, commonly known as fuel system cleaners. After adding this to the fuel tank, it enters the combustion chamber along with the gasoline and gradually dissolves the carbon deposits. I've tried it a few times myself, and remember that you need to use at least three bottles consecutively to see results. Another method is called intake manifold cleaning, where the repair shop connects a cleaning agent to the intake pipe, allowing atomized cleaning fluid to enter the engine directly. It takes about half an hour to complete and is suitable for severe carbon buildup. Nowadays, some shops use dry ice cleaning technology, which doesn't require disassembling the engine. Instead, dry ice pellets are used to blast away the carbon deposits, achieving exceptionally clean results. However, the equipment is expensive, so the service cost is high. To prevent carbon buildup, I recommend avoiding prolonged idling in the city and taking regular highway drives, which can also be quite effective.
