Knock
Combustion
abnormal combustion in the cylinder — Knock (also called pinging or detonation) is uncontrolled combustion that happens before the spark, caused by hot spots, low octane fuel, or excessive timing. Causes engine damage. ECU detects it via knock sensors and retards timing automatically.
