Abstract: Solvent extraction of karanj seed was found more efficient over traditional mechanical means for oil extraction from raw seed as the former one tested more yield. The extracted oil was subjected to acid catalyst esterification and subsequently followed by alkali catalysed transesterification to produce fatty acid methyl ester. Physical, chemical and petrochemical features of the ester as well as two different blends with diesel (B10 and B20) were measured and compared with neat diesel. Performances of these fuels were tested in an unmodified single cylinder, water cooled, four stroke direct injection type diesel engine. On sample testing it was revealed that, the emission of carbon monoxide and hydrocarbon was less than what noticed during testing diesel alone, although the emission of oxides of nitrogen was somewhat more than what noticed in available diesel engine test results while using diesel only as fuel.
