How Often Should the Combustion Chamber Be Cleaned in Terms of Mileage?

[Wilson]

The combustion chamber carbon deposits should be cleaned approximately every 40,000 kilometers. Over time, carbon deposits accumulate in the intake tract, valves, and combustion chamber. These deposits absorb fuel when the engine is cold and release it when the engine is hot, leading to difficulties in cold starts and increased fuel consumption when the engine is warm. This results in degraded engine performance, manifesting as idle shaking, poor acceleration, increased fuel consumption, and excessive exhaust emissions. Below are the hazards of carbon deposits in cars: 1. Increased fuel consumption: Carbon deposits can reduce engine power and increase fuel consumption. 2. Engine damage: In severe cases, carbon deposits can cause engine knocking, acceleration noise, and damage to pistons and crankshafts, potentially leading to engine oil burning and necessitating major repairs. 3. Impact on exhaust emissions: Carbon deposits directly affect vehicle exhaust emissions, making it difficult to pass annual emission inspections.
