Bio-Diesel produced from Waste vegetable oil(WVO), straight vegetable oil (SVO) or animal fat is as effective as Petroleum diesel.This study deals with preparation of Bio-Diesel by Transesterification of Sunflower oil (triglycerides) with Methanol and NaOH as catalyst at specific temperature resulting in formation of methyl-esters (Biodiesel). The by-product, glycerol wasseparated and the methyl-ester was washed and dried. The produced biodiesel was tested for its calorific value(38,048 KJ/Kg). The engine performance was studied with 100% biodiesel (B100) and Diesel on a single cylinder, 4 stroke compression ignition engine in terms of Mechanical Efficiency, Break Thermal Efficiency and Specific Fuel Consumption. These parameters were calculated for different loads andcompared for both the fuels. The results showed that both the fuels were very close and similar, however the specific fuel consumption for B100 was slightly higher than the Diesel.
