knocking
Knocking is a problem that happens in engines when the fuel ignites too early, making a knocking noise. It can hurt the engine, so it's important to keep it from happening.
Knocking, also known as detonation, is an undesirable combustion phenomenon in engines where the air-fuel mixture ignites prematurely, causing a knocking sound and potentially damaging the engine. It can occur when the compression ratio is too high for the fuel being used.
