How to Prevent Cylinder Scuffing in Cars?
2 Answers
Preventing cylinder scuffing in cars involves the following methods: 1. Ensure the roundness and cylindricity tolerances of the cylinder liner are within the allowable range; 2. Avoid excessively small piston ring gaps; 3. Prevent engine overheating; 4. Avoid severe lack of lubricating oil; 5. Perform a break-in period after an engine overhaul. Cylinder scuffing is one of the common faults in car engines. It refers to deep grooves being formed on the inner wall of the cylinder, causing the piston, piston rings, and cylinder wall to lose their sealing ability during friction. This results in reduced cylinder compression pressure and loss of power. The root cause of cylinder scuffing is the difficulty in forming an oil film between the inner wall of the cylinder and the piston rings or piston, leading to poor lubrication or even dry friction. There are multiple specific reasons for this condition.
Preventing engine cylinder scuffing mainly relies on daily maintenance and driving habits. Since buying the car, I've developed a habit of changing the engine oil every 5,000 kilometers, using the recommended full synthetic oil to reduce friction. In summer, I pay extra attention to the coolant level, adding distilled water or specialized fluid to prevent overheating. When driving, I avoid sudden acceleration or prolonged high-speed driving, especially keeping the speed below 120 km/h during the new car break-in period. I also avoid idling for more than 10 minutes when parked to prevent carbon buildup. Regularly visiting the shop to check the spark plugs and filters, and cleaning cylinder residues is part of my routine. My neighbor once experienced cylinder scuffing due to long-term neglect of oil changes leading to insufficient lubrication, costing several thousand to repair—a profound lesson. Simply put, diligent maintenance and gentle operation ensure engine durability.
