Performance and Emission Characteristics of Cotton Seed Oil Biodiesel blend fuel with Nano additives in CI Engine
Main Article Content
Among petroleum products, diesel is a major fuel source, but environmental degradation and depletion of petroleum reserves are serious concerns worldwide. As a result, the search for an alternative to diesel is critical. Biodiesel-diesel blends are currently earning new interest in this regard. The performance of a CI engine with
diesel, B20, B20+50ppm Al2O3, B20+50ppm CeO2, and B20+50ppm Al2O3+50ppm CeO2 fuels was investigated experimentally. For all test fuels, engine tests were; conducted to obtain comparative performance measures such
as brake power (Pb), brake torque (Tb), and BSFC, and emissions such as CO, CO2, HC, and oxygen concentration. From the experiment, the brake power of CI engine with B20+50ppmAl2O3, B20+50ppm CeO2, and B20+50ppmAl2O3+50ppm CeO2 significantly improved by 6.3%, 4.3%, 17.9% respectively. The engine brake torque was higher than diesel with fuels B20+50ppmAl2O3+50ppm CeO2. Furthermore, the engine BSFC of B20 is higher than all the test fuels; however, the addition of nano-particles improved the BSFC of the engine. Moreover for B20, B20+50ppm Al2O3, B20+50ppm CeO2, and B20+50ppm Al2O3+50ppm CeO2 fuels CO emissions reduced by 6.7%, 11.2%, 9.7% and 23.2% and emissions of CO2 reduced by 4.6%, 8.1%, 8.8% and 14.8% as compared with diesel fuel. Additionally, HC emissions from all cotton seed biodiesel blended fuels are lesser than diesel fuel. The experimental results showed that B20+50ppm Al2O3+50ppm CeO2 test fuel has performance and emission improvements compared to all other test fuels.
