4. Better atomization and _____________ will make the engine less knock prone.
a) ignition
b) vapourization
c) condensation
d) none of the mentioned
View Answer

Answer: b
Explanation: Engine knock is dependent on poor atomization and vapourization conditions, so better atomization and vapourization will make the engine less knock prone.
