Which consequence results when the crankshaft in a ship's diesel generator experiences thermal fatigue?

💡 Explanation

Engine power reduces because progressive cracking due to cyclical thermal stress initiates metal fatigue, causing crankshaft failure and reduced stroke, therefore the torque is affected, rather than changes in related parameters like oil viscosity or fuel pressure within the diesel engine's operational limits.
