[SawyerRose]

The recommended interval for cleaning carbon deposits in the engine is every 10,000 to 20,000 kilometers, and car owners can adjust this based on their actual usage conditions. The causes of carbon buildup in engines include: 1. Long-term poor driving habits of the owner; 2. Mismatch between fuel octane rating and compression ratio; 3. Aging or damage to the engine carburetor; 4. Prolonged high-load driving; 5. Failure to replace the air filter; 6. Inaccurate ignition timing or fuel injection timing; 7. Low engine temperature; 8. Poor sealing of valves and valve seats. Methods to prevent carbon buildup in engines are: 1. Regularly clean components prone to carbon deposits; 2. Avoid prolonged idling; 3. Use appropriate fuel additives; 4. Use the gasoline specified for the vehicle.
