Extraction of Simarouba Biodiesel and Experimental Investigation of its Suitability as Fuel for CI Engine

Bio-diesel is one of the most promising alternatives for diesel needs. Use of edible oils may create shortage of oil for daily food. This required identification of new kinds of non-edible vegetable oil. With this objective, the present work has focused on the performance, combustion and emission characteristics of diesel engine using simarouba oil and its blends with diesel. In this investigation, the blends of varying proportions of simarouba biodiesel with diesel (S20, S40, S60, S80 & S100) were prepared, analyzed, and compared the performance and exhaust emission with diesel using 5.2 kW Single cylinder, 4stroke diesel engine. The performance and emission characteristics of blends are evaluated at variable loads and constant rated speed of 1500 rpm and found that the performance of S20 blend of simarouba oil gives result, that is near to the diesel and also found that the emission CO, CO₂, HC, smoke & NO_X of this blend is less than the diesel.
