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 r un cars. Rapid growth of bio-fuels all around the wo rld is mainly due to energy crisis and ecological concerns , and in this dynamic market mechanisms, lot of eff orts are being made to facilitate the growth of bio-fuels. In India , the main Goal of the Biofuel Policy is to make sur e that, a bare minimum level of bio-fuels turns out to be readily accessible in the marketplace, to meet up the requi rement at any given time. A pinpointing objective of 20% blending of bio -fuels, by 2017 was to be achieved, but still we are f r behind. Even though raw vegetable oils can also be used in compre ssion ignition engines, however, their high viscosit ies, poor flow properties in cold and low volatilities have made th em unsuitable. Consequently, we need to investigate v arious other derivatives. In this research, Biodiesel was prepare d by the process of trans-esterification, from wast e cooking refined soyabean oil. Thereafter, an experimental investiga ion was carried out on a 4 – stroke Compression ig ition engine, with single cylinder which is fueled with blends of Biodie s l and petro diesel. 6 blends of biodiesel were tak en for investigating performance characteristics of engine, under differ ent conditions of load. Blend B20 of biodiesel was fo und most suitable among all blends of biodiesel and petro diesel
