How to Determine Excessive Engine Carbon Deposits?
2 Answers
Methods to determine excessive engine carbon deposits are: 1. Observe if the car experiences shaking; 2. Monitor if fuel consumption increases; 3. Check if the vehicle's power decreases. Ways to clean engine carbon deposits include: 1. Adding fuel additives when refueling; 2. Disassembling and cleaning the engine; 3. Performing an intravenous drip cleaning for the car. Causes of car carbon deposit formation are: 1. Long-term poor driving habits of the owner; 2. Mismatch between fuel grade and compression ratio; 3. Aging or damage of the engine carburetor; 4. Prolonged high-load driving; 5. Not replacing the air filter; 6. Inaccurate ignition timing or fuel supply timing; 7. Low engine temperature; 8. Poor sealing of valves and valve seats; 9. Prolonged engine idling.
I remember there was a period when the car was particularly difficult to start. During cold starts in the morning, the engine always seemed to struggle, and the idle speed fluctuated up and down, unstable as if dancing. Acceleration was noticeably sluggish, with delayed response when pressing the throttle, making overtaking a challenge. Additionally, fuel consumption increased significantly—previously, a full tank could last 500 kilometers, but now it barely reaches 400. There was also a pungent, unusual smell from the exhaust. These symptoms typically point to carbon buildup, which clogs the intake valves and pistons, affecting airflow and combustion efficiency. To confirm, you can listen for any abnormal noises while the engine is running or visit a repair shop for a professional inspection. Addressing the issue promptly can prevent worse problems, such as engine overheating or damage.
