Which outcome occurs when excessive cylinder pressure breaches the design limits of a four-stroke engine piston?

💡 Explanation

When cylinder pressure exceeds design limits, piston ring function degrades because high pressures force rings away from cylinder walls creating ring flutter and blow-by events. Therefore, piston ring flutter leads to blow-by, rather than fracture, valve float or camshaft wear that arise from other failure modes.
