Which outcome occurs when cylinder misfire induces torsional vibration in a diesel engine crankshaft?

A)Harmonic balancer reduced lifetime
B)Catalytic converter thermal runaway
C)Fuel injector nozzle clogging
D)Variable valve timing malfunction

💡 Explanation

Increased stress in crankshaft leads to harmonic balancer degraded performance, because torsional vibration amplifies cyclical stress. The dampers dissipate energy, therefore lifespan reduction, rather than catalytic issues or fuel injector problems, primarily affecting vibration damping.
