Which outcome occurs when a turbocharger overspins in a diesel engine?

A)Compressor surge damages turbine blades
B)Increased cylinder head temperatures result
C)Fuel injectors inject greater volumes
D)Engine valve float suddenly occurs

💡 Explanation

Compressor surge occurs because exceeding the turbocharger's speed limit causes reversed airflow and pressure fluctuations. Therefore turbine damages transpire, rather than increased head temperatures or injector volumes which require separate failures in those linked systems.
