Performance Evaluation of Diesel Engine Using Biodiesel Fuel Derived from Waste Cooking Refined Soyabean Oil

Brazil is using bio-diesel as an alternate fuel to run cars. Rapid growth of bio-fuels all around the world is mainly due to energy crisis and ecological concerns, and in this dynamic market mechanisms, lot of efforts are being made to facilitate the growth of bio-fuels. In India, the main Goal of the Biofuel Policy is to make sure that, a bare minimum level of bio-fuels turns out to be readily accessible in the marketplace, to meet up the requirement at any given time. A pinpointing objective of 20% blending of bio-fuels, by 2017 was to be achieved, but still we are far behind. Even though raw vegetable oils can also be used in compression ignition engines, however, their high viscosities, poor flow properties in cold and low volatilities have made them unsuitable. Consequently, we need to investigate various other derivatives. In this research, Biodiesel was prepared by the process of trans-esterification, from waste cooking refined soyabean oil. Thereafter, an experimental investigation was carried out on a 4 – stroke Compression ignition engine, with single cylinder which is fueled with blends of Biodiesel and petro diesel. 6 blends of biodiesel were taken for investigating performance characteristics of engine, under different conditions of load. Blend B20 of biodiesel was found most suitable among all blends of biodiesel and petro diesel
