← TechnologyWhich outcome occurs when excessive cylinder head deformation happens in high-performance diesel engine piston?
A)Piston ring land micro-welding✓
B)Fuel injector nozzle clogging carbon
C)Crankshaft main bearing cavitation
D)Valve stem oil seal deterioration
💡 Explanation
When excessive cylinder head deformation occurs, localized high temperatures and pressures cause the piston ring lands to experience deformation, increasing the risk of micro-welding to the piston rings. Therefore piston ring land micro-welding results rather than clogging, cavitation or deterioration which stem from different triggers and processes.
