← TechnologyWhich outcome occurs when excessive cylinder head pressure overcomes piston assembly strength?
A)Piston ring flutter and blow-by✓
B)Increased lubrication oil consumption instantly
C)Connecting rod bearing starvation rapidly
D)Detonation rapidly increases in severity
💡 Explanation
High pressure causes immediate increased piston ring flutter because elastic deformation changes ring sealing geometry; therefore increased oil and combustion gases bypass the pistons. Rather than bearing starvation directly impacting the rod, ring malfunction is causative.
