Which outcome occurs when engine oil supply to a turbocharger bearing is interrupted during high-speed operation?

💡 Explanation

When oil supply is cut during high-speed, boundary lubrication fails and hydrodynamic lubrication ceases in the turbocharger bearing because of increased friction and heat, causing rapid metal contact and welding. Therefore, turbine shaft seizure results, rather than improved efficiency, EGR blockage or injection increase, requiring different system failures.
