A knocking engine sound, often described as a metallic pinging or rattling noise, is a distinct indication of improper combustion occurring within an engine's cylinders. This phenomenon, commonly referred to as "engine knock" or "detonation," arises when fuel-and-air mixture ignites prematurely due to excessive heat and pressure in the combustion chamber, rather than from the spark plug's ignition. The sound resembles someone tapping on the engine with a small hammer, albeit rapidly. This can lead to significant engine damage over time if not addressed. Causes range from using fuel with a lower octane rating than recommended, to advanced ignition timing or carbon deposits. Addressing engine knock typically involves using the correct fuel grade, ensuring the ignition system is properly timed, and keeping the engine well-maintained to prevent carbon buildup.
