Increasing oil prices and global warming activates the research and development of substitute energy resources to maintain economic development. The methyl esters of vegetable oil, known as biodiesel are becoming popular because of their low ecological effect and potential as a green substitute for compression ignition engine. Diesel engines are more efficient and cost effective than other engines. An experimental study was conducted to study the effect of blending esterified vegetable oil (mustard oil) by different volume with diesel fuel. Performance and emissions of a 4- stroke diesel engine comprising of single cylinder. The engine ran at different torque but at a constant speed where diesel is considered to be the base fuel. As mustard oil is highly viscous oil, therefore it is not directly mixed with diesel fuel. Instead velocity must be reduced for the test fuel. This can be done by many methods viz trans-esterification, mixing with very less viscous fuel etc. here trans-esterification was preferred. Three blends were prepared being 10%, 20% and 30% and blended with diesel fuel named B10, B20 and B30 respectively. Performance parameters that were observed involved bsfc, brake thermal efficiency and exhaust gas temperature, whereas emissions that were analyzed were Nitrogen oxides (NOx) and carbon dioxide(CO2), total Hydrocarbon (HC), Carbon monoxide (CO) and smoke opacity (SO). Bsfc got reduced by nearly 4.67% when B30 was used in place of B10 in the blend thus indicating decrease in bsfc when oil percentage was increased. NOx, CO2 and unburnt total hydrocarbon were found to increase with increase in biofuel percentage by 17.25%(B10), 13.46%(B10) and 30%(B20) respectively at full load capacity but CO and SO were were found to decrease by nearly 33.33% and 32.83% (for B10) respectively at full load capacity.
