Are There Any Aftereffects After Repairing a Car with Cylinder Scoring?
1 Answers
Generally, there are no aftereffects after repairing a car with cylinder scoring. Below is an introduction to cylinder scoring in cars: 1. Introduction: Cylinder scoring refers to the 'welding' and scuffing of the piston, piston rings, and cylinder liner surface due to high temperatures. 2. Definition: It occurs when the oil film between the piston and cylinder liner is interrupted, leading to dry friction. The intense frictional heat causes microscopic melting and adhesion of the metal, tearing nearby metal particles. 3. Cause: The root cause of cylinder scoring is the interruption of the oil film. To meet gas sealing requirements, the gap between the piston rings and cylinder liner should be as small as possible, which creates unfavorable lubrication conditions. The friction between the cylinder liner and piston rings depends on factors such as piston ring tension, operating temperature, sliding speed, oil film distribution, component quality, and break-in conditions.
