Which risk increases when thermal expansion mismatches between different crankshaft sections?

💡 Explanation

When thermal expansion mismatches occur, differential stresses develop within the crankshaft because differing expansion rates cause misalignment and distortion relative to main bearings, disrupting the oil film and leading to potential bearing seizure. Therefore oil film disruption and bearing seizure is the result, rather than valve float, piston increase, or detonation failures arising from distinct mechanisms.
