  • Abstract:
  • The rapid depletion of fossil fuels and environmental concerns make alternative fuels such as biodiesel more attractive. Biodiesel has properties similar to pure diesel. However certain properties of biodiesel such as viscosity, calorific value, density and volatility differ from pure diesel. These properties strongly affect injection, air-fuel mixing and there by combustion and performance characteristics of biodiesel in a diesel engine. The current work has carried out on vertical single cylinder 4-stroke compression ignition (CI) diesel engine, to investigate the performance and emission characteristics of diesel engine using two bio-diesels namely Simarouba bio-diesel and Pongamia bio-diesel in the ratio of (S50+P50),(S75+P25) and (S25+P75). In this study blends B0, B20, B40, B60, B80 and B100 at an engine speed of 1500rpm has tested. It has shown that there is a marginal increase in BSFC and decrease in BTE, in blending bio-diesel at constant injection pressure. Emission of CO, UBHC and NOx are lowered in bio-diesel and diesel blends. The blend (S50+P50) has shown the superior performance than (S75 +P25) and (S25+P75) blends.
