Detonation

Or pre-ignition is a potentially engine-damaging condition in which part of the fuel/air mixture ignites before the piston is at top dead center (TDC). Pre-ignition is a result of poor ignition timing and can be heard as 'engine knock'. In nitro engines, the proper combination of glow plug and nitro content will prevent this.
