Which issue arises in an internal combustion engine when excessive cylinder pressure causes deformation of the crankshaft throws?

💡 Explanation

Harmonic imbalance and vibration occur because crankshaft throw deformation changes the mass distribution, leading to imbalances that excite resonant frequencies. Therefore, the engine vibrates severely, rather than a localized issue like injector/valve failure or external parts overheating unrelated to crankshaft balance.
