← TechnologyWhich consequence results when unburnt fuel washes down cylinder walls?
A)Increased piston ring wear rate✓
B)Reduced turbocharger spooling speed
C)Elevated exhaust valve temperatures
D)Decreased fuel injector nozzle clogging
💡 Explanation
Increased piston ring wear happens due to oil film dilution, because fuel acts as a solvent, stripping away lubrication. The dominant mechanism is abrasive wear. Therefore, ring wear increases, rather than other thermal or fuel-related effects.
