Which outcome occurs when increased pre-ignition bends a crankshaft?

💡 Explanation

Increased pre-ignition elevates pressures which overload the crankshaft causing plastic deformation; this is known as crankshaft bend. Accelerated bearing fatigue results because the changed geometry increases stress concentrations on the bearing surfaces, therefore, answer A, rather than influencing efficiency or displacement.
