Does More Engine Carbon Deposits Cause Noise?
3 Answers
Engine carbon deposits can indeed cause noise, as one of the reasons for increased engine noise is excessive carbon buildup. In urban areas, traffic congestion and idling on the road are common occurrences, but these poor driving habits can lead to carbon deposits inside the engine. If left uncleaned for a long time, it can result in car shaking, reduced power, and increased noise. The engine is the heart of a car, and the quality of a car largely depends on the engine's performance. Engine maintenance is a crucial part of car upkeep, primarily involving oil changes and carbon deposit cleaning. To clean carbon deposits, you can remove the throttle and engine interior, use a carburetor cleaner for cleaning, and then wipe dry with a cotton cloth.
Excessive engine carbon deposits can indeed cause noise, primarily because these deposits accumulate on the piston tops or valves, altering the combustion chamber's shape and increasing the compression ratio, which leads to knocking—a phenomenon that produces a tapping or metallic clanging sound similar to piston slap. This is especially noticeable under high load. In my daily repair work, I often hear car owners complain about this noise, which is not only annoying but also indicates that carbon deposits are interfering with normal combustion, possibly accompanied by sluggish acceleration and increased fuel consumption. It is recommended to use fuel system cleaners regularly to remove carbon deposits and prevent the issue from worsening. Severe carbon buildup can lead to costly overhauls, so any abnormal noise should prompt an immediate inspection. Professional cleaning often eliminates the noise and can extend engine life. Remember, noise is the engine's cry for help.
My car had a similar experience before. There was always a clicking noise from the engine during acceleration. The mechanic diagnosed it as knocking caused by excessive carbon deposits, sounding like small hammers tapping. After the noise appeared, the power also deteriorated, and starting became more difficult. After one engine cleaning, it became much quieter. Carbon buildup can lead to additional wear and tear, with noise being just the surface symptom. It may also be accompanied by excessive oil consumption or abnormal temperatures. For daily maintenance, it's recommended to use high-quality gasoline and add cleaning agents to reduce carbon deposit formation. Don't underestimate any abnormal noises, as they might save you a significant amount on future repairs.
