← TechnologyWhich outcome occurs when fuel impinges the cylinder liner?
A)Increased lubricating oil dilution✓
B)Optimized combustion chamber efficiency
C)Decreased thermal NOx formation
D)Reduced peak firing pressures
💡 Explanation
Lubricating oil dilution increases significantly, because fuel washes down the unprotected surfaces, thinning the oil film; piston ring sealing is compromised. Therefore, oil degradation accelerates rather than cleaner combustion, which fuel film formation inhibits.
