← TechnologyWhich detrimental outcome occurs when a turbocharger experiences sustained thrust overload?
A)Compressor surge and impeller damage✓
B)Increased catalytic converter efficiency
C)Improved boost response at low RPM
D)Reduced exhaust backpressure overall
💡 Explanation
Compressor surge occurs thanks to the stall of airflow near the blades because the excessive backpressure overwhelms the ability of the turbocharger's impeller to effectively compress air. Therefore, surge damages the impeller rather than increasing efficiency or reducing backpressure.
