Optimization of CI Engine Performance and Emissions Fueled by Blends of Alternative Fuels Methyl Ester Using Taguchi and Multi Regression Analysis 2019-01-1893

Today’s frenetic engine manufacturing and transportation sector and its related traces viz; noise and vibration of our modern societies has adverse effect on environment as well as all of us. Modern research affords us the opportunity to understand the subject better and to develop advance technologies. Widely immediate slogan and goal of all industries might be to improve the performance and reduce emission using alternative fuel while, make the quietest and smoothest running Engines. To, reduce the dependency on diesel fuel (Due to rapid worldwide depletion) Biodiesel is one of the immediate, alternative and complimentary solution. In the Present study, to optimize the operating parameters of the Direct Injection Single Cylinder (5.2 kw) CI engine with respect to Brake Thermal Efficiency (BTE), Carbon monoxide (CO), Oxides of Nitrogen, Hydrocarbons (HC) etc.. For this investigation, we used Biodiesel as an alternate fuel for diesel fuel which possesses low cetane number which is not sufficient to operate existing diesel engine. However, this could be combined with the diesel fuel in the form of blends. For this investigation four levels and four parameters were selected viz; Fuel Fraction (FF), Compression Ratio (CR) Injection Pressure (IP), and Injection Timing (Before TDC). To minimize the number of experiments efforts, L16 orthogonal array (DOE-Design of Experimental) is designed by Taguchi technique. Taguchi Method is used for minimizing the number of experiments and Multiple Regression Analysis is used to find the optimum condition. Outputs variables such as; Brake Thermal Efficiency (BTE), content of HC particles, NOx, CO etc. in the emission are measured were considered its influence on CI Engine performance and emissions. The test was carried out at full load condition and the optimization is carrying out the further experimentation were the optimized condition compare viz; performance and emission with diesel at optimal combination of Input parameters. Keywords; Alternative Fuel, Compression Ignition Engine, Biodiesel, Taguchi, Multiple Regressions, Performance, Emission.
