Engine knock is pinging sound, sometimes it may hear from an operating engine. A rapid auto - ignition of a portion of the fuel mixture in the cylinder generates a local pressure pulse, leading to pressure oscillations, propagating across the cylinder. These oscillations create noise outside the engine, which is called ‘‘knock’’. Knocking in engine has some unfavourable effects such as increa se in engine pollution, decrease in engine efficiency, considerable rise in engine specific fuel consumption and possibility of structural harms to engine in a long - term period. Thus, detection and prevention of this problem is of high importance. For this Analysis, the Experimental work is carried out to measure the vibration fuelled in diesel and biodiesel B20 (Mahua MEOM) at different load (20%, 40%, 60%, 80% and 100%)
