Which outcome occurs when inadequate fuel atomization happens?

A)Reduced combustion efficiency.
B)Increased engine knock.
C)Decreased exhaust backpressure.
D)Elevated catalytic converter temperature.

💡 Explanation

Reduced combustion efficiency results from insufficient fuel atomization; the surface area for reaction is reduced, because the fuel/air mixture is less homogeneous, leading to incomplete combustion and lower energy release; therefore, efficiency decreases, rather than a knock arising from pre-ignition.
