Is Carbon Deposit Cleaning Necessary?
2 Answers
Cleaning carbon deposits is necessary because there is currently no complete method to prevent their formation. Without regular cleaning, carbon deposits can accumulate indefinitely. Once carbon deposits build up, minor issues such as engine shaking and reduced power may occur; in severe cases, it can lead to engine cylinder scoring, seizure, or even knocking. Therefore, regular cleaning of engine carbon deposits is essential. Causes of carbon deposit formation: 1. Prolonged operation under heavy load; 2. Frequently pressing the accelerator heavily at low RPM; 3. Extended idling or low-speed operation; 4. Excessive warm-up time after cold starts; 5. Driving at high gears with low RPM.
As an automotive enthusiast, I often pay attention to engine maintenance, and carbon deposit cleaning is indeed necessary. Carbon deposits are residues from fuel combustion that accumulate on cylinders or valves. Over time, they can clog the fuel injection system, leading to sluggish acceleration, rough idling, and a surge in fuel consumption. In severe cases, they may cause pre-ignition or knocking, damaging the engine's core components. I recommend professional cleaning or using additives for removal. Additives are suitable for minor carbon buildup, but moderate to severe cases require disassembly for treatment. Frequent short-distance driving with constant stop-and-go is more prone to carbon deposit accumulation, so it's wise to inspect and clean every 20,000 kilometers or so. Neglecting it could escalate into major repairs, costing more money. After cleaning, I personally experienced quicker throttle response, restored power, and overall reduced maintenance costs.
