← TechnologyWhich risk increases when fuel injectors remain open after an engine cylinder's piston reaches top dead center?
A)Hydraulic lock from liquid accumulation✓
B)Piston ring failure from thermal shock
C)Catalytic converter overheating from rich mixture
D)Crankshaft bearing damage from detonation
💡 Explanation
When fuel injectors remain open, liquid fuel accumulates in the cylinder compromising compressibility because of phase changes occurring, leading to hydraulic lock. Therefore damage risk increases rather than ring or converter failure that needs other causes or bearing damage relying on engine load and pressure changes.
