Compressive Stress in Engine Push Rod Formula

What is meant by knocking in engine?

Knocking in an internal-combustion engine, sharp sounds are caused by premature combustion of part of the compressed air-fuel mixture in the cylinder. In a properly functioning engine, the charge burns with the flame front progressing smoothly from the point of ignition across the combustion chamber.
