Which outcome is triggered during piston ring failure caused by thermal runaway within an internal combustion engine?

💡 Explanation

Cylinder scoring results because thermal runaway causes localized high temperatures which trigger adhesive wear, due to boundary lubrication breakdown. Therefore, scoring occurs rather than changes in lubricant because the piston ring material yields past design limits.
