Which risk significantly increases when fuel injectors in a gasoline engine experience incomplete atomization?

A)Elevated exhaust emissions and catalyst damage✓

B)Cylinder misfire due to retarded timing

C)Increased oil viscosity and reduced lubrication

D)Coolant boiling and engine head distortion

💡 Explanation

When fuel injectors incompletely atomize fuel due to nozzle clogging or low pressure, larger droplets persist because the surface area for evaporation is reduced, leading to incomplete combustion and higher unburned hydrocarbon emissions, damaging the catalyst. Therefore, increased emissions and catalyst damage result, rather than misfire, lubrication issues, or coolant boiling.
