← TechnologyWhich outcome arises when hydraulic lock occurs in a diesel engine?
A)Increased connecting rod stress.✓
B)Turbocharger overspeed failure.
C)Elevated fuel rail pressure.
D)Valve timing synchronization error.
💡 Explanation
Increased connecting rod stress results, because water ingestion prevents piston compression, leading to extreme pressure during the compression stroke. This causes catastrophic stress via incompressible LOCKED VOLUME of water, therefore rods can break rather than piston moves freely.
