EXPERIMENTAL INVESTIGATION ON CHARACTERISTICS OF DI-CI ENGINE FUELED WITH SHEA OLEIN BIODIESEL

The Scarcity for the petroleum resources is getting increasing and its exhaustion makes to search for other alternative fuels. Among the number of other alternate ways of searching the substitution fuels for diesel engines one way is attempting development of Biodiesel as alternative fuel. Here also an attempt was made to develop Shea olein biodiesel and experimental investigation is focused on the DI-CI with different blends of shea olein biodiesel. In the present work performance characteristics like Brake thermal efficiency, Specific fuel consumption, exhaust gas temperature, combustion characteristics like pressure variation, and emission characteristics like CO, NOX, and HC have been investigated. From the results it is observed that all the characteristics of the diesel engine with shea olein methyl ester are similar to that of petroleum diesel fuel. Hence shea olein methyl ester can be used in the existing diesel engine without any modifications.
