A diesel engine failing to atomize fuel efficiently causes which risk?

A)Incomplete combustion, soot formation within cylinders
B)Rapid cylinder cooling induces thermal shock
C)Increased fuel density causes engine stalling
D)Advanced combustion timing creates pre-ignition knock

💡 Explanation

Incomplete atomization leads to incomplete combustion because fuel droplets are too large; this inhibits proper mixing and Oxidation, resulting in soot formation rather than complete oxidation to CO2 and H2O. Therefore soot increases, rather than enhanced combustion, proper atomization, or changed timing.
