Abstract
The incomplete combustion that occurs in gasoline or diesel engines, lead to enormous rejection of atmospheric pollutants such as soot particles, CO, NOX, and SO2. These toxic gases contribute to the formation of greenhouse effect. Reducing these GHG emissions are very important in preventing their climate change and hazardous effects on environment and health. Usage of the biodiesel blend as an alternate fuel will reduce the level of emission and helps to build up eco-friendly environment. The present study attempted to produce bio-diesel from fatty leather liquid and solid wastes such as wet back, chamois wash water, degreasing water and evaluated the combustion, performance and emission characteristics using a single cylinder, air cooled, direct injection compression ignition engine. The mixture of leather solid wastes and effluents were heated upto 100 °C and fat content present in the aliquot was extracted. The extracted fat was used in the acid base trans-esterification and the biodiesel was produced. The bio-diesel yield was found to be 0.08L/L of chamois leather processing waste and 0.15kg/kg of pickled fleshing. It was noticed that the addition of biodiesel into the petroleum diesel fuel reduced the Specific energy consumption at no load, part load and 75 % load, but there is no significant difference at full load condition. There is significant rise on heat release rate of B10, B20 and B50 at no load. For B10, B20 and B40 there is significant rise on rate of heat release at 25 % load. There is significant rise on heat release rate for B10, B20 and B50 at part load condition. Similarly for B10, B50 and B20 at 75 % load and B50, B10, and B20 at full load condition than the petroleum diesel fuel. There was a considerable increase in thermal efficiency of biodiesel blends than diesel fuel due to the presence of oxygen in biodiesel. It was also observed that for all blends there is increase in NOx emission at 25 % load and slight variation for the remaining loads. When compared to conventional diesel fuel the CO2 emission increased for all biodiesel blends at all loads. Due to the oxygen content present in the biodiesel the combustion was improved and the emission was reduced. There was a significant reduction in both the CO and HC at all load conditions.
