← TechnologyWhich condition arises following excessive piston ring wear within a diesel engine?
A)Increased oil consumption and blue smoke✓
B)Decreased compression ratio and misfires
C)Elevated coolant temperature and boilover
D)Premature fuel injector failure and knocking
💡 Explanation
When piston rings wear excessively, blow-by increases because the seal weakens between the piston and cylinder wall causing combustion gases and oil to leak into the crankcase. Therefore, increased oil consumption and blue smoke result, rather than other engine problems which require different failure mechanisms in other subsystems.
