Which risk increases when a turbocharger impeller overspeeds beyond crankshaft's torsional resonance frequency due to boost control failure?

💡 Explanation

When the turbocharger impeller exceeds the crankshaft's torsional resonance frequency, harmonic vibrations are amplified because the crankshaft's natural frequency is excited, leading to cyclical stress and accelerated fatigue. Therefore, crankshaft fatigue increases, rather than injector clogging, ring failure or lag reduction, which are consequences tied to different operational issues.
