Is It Necessary to Clean Carbon Deposits in the Engine?
2 Answers
It is necessary to clean carbon deposits in the engine. The causes of engine carbon deposits 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. Methods to prevent engine carbon deposits include: 1. Regularly cleaning parts prone to carbon buildup; 2. Avoiding prolonged idling; 3. Using suitable gasoline additives; 4. Using the gasoline specified for the vehicle.
Honestly, I think cleaning engine carbon deposits is quite necessary, especially for someone like me who drives a decade-old car. When carbon builds up in the engine, you'll notice obvious shaking after starting, sluggish acceleration, and a noticeable increase in fuel consumption. I've experienced this myself—after one carbon cleaning session, the car ran much smoother with reduced noise. Of course, I don't do it every time; I usually check based on mileage—around 30,000 to 40,000 kilometers, I'll inspect components like spark plugs or read fault codes to confirm carbon buildup before cleaning. Method-wise, DIY fuel additives are budget-friendly but offer limited results, while professional walnut blasting is pricier but more thorough. Risks? Long-term neglect can lead to engine component wear, but improper cleaning might also damage cylinder walls. For prevention, using higher-quality gasoline and occasional highway driving can reduce carbon formation. Bottom line: don't wait for major issues—spend a little now to avoid bigger repair bills later.
