A » Engine knocking, or detonation, occurs when fuel-air mixture ignites prematurely in the combustion chamber, causing a knocking sound. This can result from low-octane fuel, incorrect ignition timing, or overheating. To prevent it, use higher-octane fuel, ensure proper engine tuning, and maintain cooling systems. Regular maintenance and using manufacturer-recommended fuel and settings are crucial to avoid detonation and ensure optimal engine performance.
