An Experimental Investigation on Performance and Emissions Characteristics of Jatropha Oil Blends with Diesel in a Direct Injection Compression Ignition Engine
Abstract Continuous effort to reducing pollutant emissions, especially smoke and nitrogen oxides from internal combustion engines, have promoted research for alternative fuels. Vegetable oils, because of their agricultural origin and due to less carbon content compared to mineral diesel are producing less CO2 emissions to the atmosphere. It also reduces import of petroleum products. In the present contribution, experiments were conducted using Jatropha oil blends with diesel to study the effect on performance and emissions characteristics of a existing diesel engine. In this study viscosity of Jatropha oil was reduced by blending with diesel. A single cylinder, four stroke, constant speed, water cooled, diesel engine was used. The results show that for lower blend concentrations various parameters such as thermal efficiency, brake specific fuel consumption, smoke opacity, CO2, and NO x emissions are acceptable compared to that of mineral diesel. But, it was observed that for higher blend concentrations, performance and emissions were much inferior compared to diesel.
