Depleting the sources of petroleum pushes the researchers to find hopeful alternate for future. From the extensive study of many researchers results that, Biofuel having the potential used as fuel in compression ignition engine. Biofuel derived from Ziziphus jujuba (Indian jujube), which is the edible in nature, first time introduced as fuel to run single cylinder, four stroke, variable compression ratio diesel engine. Experimental investigation of diesel engine was made with 20% (B20), 40% (B40) and 60% (B60) blending of Ziziphus jujuba oil with diesel for compression ratio from 15:1 to 18:1 and the results were compared with diesel. Performance parameters such as Specific fuel consumption, Brake thermal efficiency and Exhaust gas temperature for varying compression ratio and blending has been presented.
