On the other hand, detonation can occur at any point during the combustion process. It is basically a violent and uncontrolled explosion in the combustion chamber. Although folks commonly refer to combustion as an "explosion" it is actually more appropriately termed a "controlled burn". Explosions in the combustion chamber are undesirable, and the violent release of energy can also destroy an engine. Pre-ignition can sometimes lead to detonation because the premature burn is simultaneously compressed. Pre-ignition and detonation are both bad news. Detonation is usually caused by a *lean* A/F mix. (Vacuum leaks) or improper jetting. Also by low octane fuel,over advanced timing, lugging of engine, and of course excessive carbon in the combustion chamber. A rich mixture can lead to detonation due to excessive carbon buildup in the combustion chamber decreasing its volume and raising the compression excessively.
