In view of the threat of unstable supply and cost escalation of petroleum fuel in near future, this being a nonrenewable source of energy, the search for alternate fuel, for compression ignition has assumed great significance. Use of renewable vegetable oil or animal fat based biodiesel appears to be viable alternate to the commercial petroleum diesel. Amongst various biomass based fuel option being searched for diesel, biodiesel blends have considerable promise because of their comparable fuel properties to that of diesel. Biodiesel is an oxygenated, nontoxic, sulphur free, biodegradable and renewable fuel. In this project, evaluation of food based and non-food based biodiesel has been made for four biodiesel blends. Fuel injection pressure plays a very important role in the combustion process of diesel engine and hence affects the engine performance. The injection pressure in diesel engines is usually set at a level recommended for petroleum diesel. Effect of variation of injection pressure on the performance of biodiesel blends and smoke levels at respective pressure is analysed in this project. This will give important perspective on how biodiesels blends can give performance comparable to petroleum diesel.
