Which consequence results when lubricating oil supply fails within an internal combustion engine?

💡 Explanation

Piston scoring and cylinder seizure occur because the oil film normally prevents direct metal contact, a *boundary lubrication failure*. Therefore, increased friction causes overheating and galling, rather than affecting the fuel injectors or catalytic converter due to lack of lubrication.
