Quizplus · Accepted Answer

Preignition occurs when the air-fuel mixture in an engine's cylinder ignites before the spark plug fires, while detonation (also known as knocking) happens when the air-fuel mixture explodes instead of burning smoothly after the spark plug fires. These are two distinct phenomena related to improper ignition timing in engines.
