ABSTRACT
ABSTRACT: Biodiesel is a renewable energy source and an alternate fuel for compression ignition engines as an alternative for diesel. Biofuel satisfies the physical and chemical standards of diesel. Hence it can be used as an alternative for diesel in compression ignition engines. Compared with normal diesel, biodiesels cause less pollution. The main objective of this experimental study is to compare the various properties of pure diesel, fish biodiesel, coconut testa biodiesel, coconut testa Biodiesel-Ethanol-Diesel blend (BED), which are made up of 5 vol% of ethanol and 10 vol% of biodiesel to 85 vol% diesel fuels, and coconut testa Biodiesel-Ethanol blend (BE), which are made up of 5% ethanol and 95% biodiesel. Properties such as flash-fire point, density, viscosity, Acid Value (AV), Saponification Value (SV), Iodine Value (IV), and calorific value of different biodiesels were analyzed.
