Which risk increases when internal combustion engine misfires consistently in one cylinder?

💡 Explanation

When one cylinder misfires, the unbalanced combustion introduces strong pulsed torques because the power stroke lacks damping, exciting torsional resonance in the crankshaft which can lead to fatigue failure at stress concentration points. Therefore crankshaft torsional resonance amplifies, rather than catalytic converter issues, coolant issues, or fuel pump issues.
