Abstract

Increased environmental awareness and depletion of resources are driving industry to develop viable alternative fuel from renewable resources that are environmentally more acceptable. Vegetable oil is a potential alternative fuel. The most detrimental properties of vegetable oils are its high viscosity and low volatility. Biodiesel is a renewable biodegradable and non-toxic fuels derived from vegetable oils and fats by trans-esterification process. As an alternative fuel biodiesel has attracted considerable attention during the past decades. The main hurdle to the commercialization of biodiesel is the cost of raw materials. Use of edible oils as biodiesel feedstock cost about 60-70% of raw materials cost. Non edible, inexpensive, low grade, high free fatty acid rice bran oil as a raw material by continuous trans-esterification process and purification of bio-active compounds from biodiesel as by-product are primary options considered to lower the cost of biodiesel. The present research is aimed to investigate experimentally the performance and exhaust emission characteristics of a direct injection diesel engine having standard piston fuelled with conventional diesel fuel, blend of diesel and rice bran oil biodiesel, and blends of diesel and rice bran oil biodiesel with varying proportions of Nano materials (Al2O3) as additives over the entire range of load on the engine. The piston in the diesel engine is replaced and then fuelled with the above said fuels. The performance parameters such as brake power, specific fuel consumption, thermal efficiencies are calculated based on the experimental analysis and engine emissions such as CO, HC, CO2, and NOx emissions are measured. The data has been analyzed and the results are presented and discussed in this project.
