Evaluation of performance and emission features of Jatropha biodiesel -turpentine blend as green fuel

An experimental study was conducted to measure the suitability of Jatropha biodiesel-Wood Turpentine blend as a replacement for diesel fuel in a compression ignition engine. Tests were performed in a four stroke, single cylinder, air cooled diesel engine. The results show that the performance factors for various blends were found to be near to diesel, emission features were improved and combustion characteristics were found to be comparable with diesel. The brake thermal efficiency of the blends establishes 9.2% lower than that of diesel at 75% load. Brake specific fuel consumption increases for blends at part load and remains same at full load. Carbon monoxide, Hydrocarbons and Smoke emissions were reduced by 75%, 64-78% and 33- 66% respectively compared to diesel at 75% load. Nitric oxides were increased. Jatropha biodiesel-Wood Turpentine blends offered comparable performance and combustion features, reduced emissions and it is capable of replacing standard diesel in compression ignition engines.
