Which consequence occurs when lubrication fails in a diesel engine?

💡 Explanation

Increased frictional heat generation happens due to the mechanism of adhesive wear, because without lubrication, surfaces directly contact and generate significant friction. Therefore, heat increases, rather than efficiency, since there's no fluid boundary and energy dissipated is much greater.
