knoking
Knocking refers to the phenomenon of premature ignition of the fuel-air mixture within an internal combustion engine's cylinder. It occurs when the mixture ignites spontaneously before the spark plug fires, or when multiple flame fronts collide. This uncontrolled combustion results in a sharp, metallic pinging or rattling sound, often referred to as "engine knock" or "detonation."
The primary cause of knocking is excessive cylinder temperatures and pressures, which can be exacerbated by
While a mild, occasional knock might not cause immediate damage, persistent and severe knocking can be detrimental
