Which failure mode is accelerated when a turbocharged engine experiences overspeed?

💡 Explanation

Excessive rotational speed in turbochargers increases centrifugal forces, leading to **creep deformation** of its bearings. This occurs because the material yields under sustained high stress, therefore bearing wear accelerates due to oil starvation, rather than damage to fuel injectors or catalytic converters.
