Knock numbers, also known as octane ratings, are a measure of a fuel's resistance to engine knocking or pinging. Engine knocking occurs when the air-fuel mixture in the combustion chamber ignites prematurely, causing a knocking sound and potentially damaging the engine. The higher the knock number, the greater the fuel's resistance to knocking. In general, higher performance engines require fuels with higher knock numbers to prevent knocking and optimize performance. **
