WebWhat is detonation in SI engine? Detonation is spontaneous combustion inside the cylinder AFTER the spark plug fires. It is similar to Pre-Ignition, but it is different. This causes a brief, but intense, spike in cylinder pressure. Detonation is also called an ” Engine Knock”, ” Knocking “, or “Pinging” because of the sound it makes.

"When unburned fuel/air mixture beyond the boundary of the flame front is subjected to a combination of heat and pressure for a certain duration (beyond the delay period of the fuel used), detonation may occur. Detonation is characterized by an almost instantaneous, explosive ignition of at least one pocket of fuel/air mixture outside of the flame front. A local shockwave is created around each pocket, and the cylinder pressure will rise sharply – and possibly beyond its desig… " - Detonation in an engine
