Effect of Rice husk nanoparticles as additives on the Performance and Emission characteristics of Tannery fleshing waste oil Biodiesel on Compression Ignition Engine
Main Article Content
Abstract
The study is to reduce the exhaust emissions of compression-ignition (CI) engine fueled with tannery fleshing waste oil methyl-ester (TOME)-diesel blends by adding the organic fuel additive called Rice Husk (RH) nanoparticles. The synthesized TOME was mixed with diesel in two ratios such as 10% (TB10) and 20% (TB20) by volume basis. To this TB10 and TB20 fuels, 5 grams (0.5% by mass) of RH nano-additive was blended. The study revealed that the direct use of TB10 and TB20 fuels show higher brake specific fuel consumption (BSFC) and lower brake thermal efficiency (BTE) as compared to the neat diesel (ND). A reduced emission of Hydrocarbon (HC), Carbon monoxide (CO), smoke opacity and an increased emission of NOx is observed in TB10 and TB20 fuels as compared to Neat Diesel (ND). The BTE is found to be improved with TB10+0.5RH and TB20+0.5RH blends in comparison with TB10 and TB20 fuels at peak-load. For TB20+0.5RH at full loads, the smoke, HC and CO emission is decreased about 33.6%, 38.2% and 26.5%, respectively and NOx is increased up to 36.5% as compared to ND.
