Which operational hazard develops when lubricating oil supply to a turbocharger bearing fails in a diesel engine?

💡 Explanation

When oil supply fails, boundary lubrication transitions to dry friction at the turbine shaft bearings because heat dissipation plummets, leading to rapid temperature rise and differential thermal expansion of the rotor. Therefore rotor seizure occurs, rather than surge, dilution, or pre-ignition, which require related but distinct failure mechanisms.
