Abstract

Abstract: : Biodiesel was prepared from Soapnut oil through transesterification process and it was blended with diesel in two concentration ratios of 20% and 30%. Later the performance and exhaust emissions of a Cl engine were experimentally investigated when the engine was fuelled with biodiesel-diesel blends. The experimental data was compared with baseline diesel. The important findings are as follows: BSFC for biodiesel blends is comparable to diesel fuel at different loads. BTE is optimum for biodiesel blends at 830. All blends showed good ITE as compared to diesel. Bio-diesel has shown highest mechanical efficiency compared to diesel. Biodiesel-diesel blends is the least contributor of CO and CO2 emissions when compared to Diesel. Overall, the optimum is found to be regarding blend wise 830 is considered to be better in getting mechanical efficiency.B20 gives the low emissions.
