Engine knocking: Abnormal combustion, Knock detection & Normal combustion

In spark-ignition internal combustion engines, knocking (also called knock, detonation, spark knock, or pinging) occurs when combustion of some of the air/fuel mixture in the cylinder results from a source other than the flame front ignited by the spark plug, in other words, when one or more pockets of air/fuel mixture explode outside the envelope of the…
