← TechnologyWhich outcome results when extreme pre-ignition forces cylinder pistons?
A)Detonation induced mechanical piston failure✓
B)Increased volumetric combustion equivalence ratio
C)Optimized thermal lower engine efficiency
D)Reduced catalytic converter stoichiometric imbalance
💡 Explanation
Detonation creates shockwaves, inducing mechanical failure resulting from excessive cylinder pressure increases; therefore, the pistons fail rather than combustion optimizing, because the structural material limits are surpassed under abnormal conditions.
