Detonation is:

Explanation:
Detonation is an abnormal, explosive-like combustion in a spark-ignited engine where the remaining unburned fuel–air mixture autoignites and a shock wave forms. This causes a sharp, high-pressure spike in the cylinder and is often heard as a pinging or knocking sound. It’s different from pre-ignition, which is the fuel–air mixture igniting before the spark plug fires due to hot spots or hotspots in the cylinder. It’s also not backfire, which is flames propagating back through the intake or exhaust, or a misfire, which is simply a failure to ignite at all. So, the best description of detonation is that rapid, unintended combustion that creates a damaging pressure rise in the cylinder, commonly referred to as detonation or knock.
