Analysis of CI Engine Parameters with Used Temple Oil Biodiesel Using Taguchi Method

Today’s world is facing major environmental issue called global warming, the emissions of diesel fuel is one of the major source for the global warming and also for air pollution. The use of biodiesel can reduce diesel fuel consumption and emission of diesel engine, because biodiesel has been considered as a potential alternative fuel for CI (Compression Ignition) engines. Out of many biodiesel derived from various resources, present study deals with usage of Used Temple Oil have been considered as fuel for analysis. The transesterfication process was adopted to condition the raw oil to suit its properties. Properties are evaluated according ASTM standard and properties are found to be computable with diesel. The present work Used Temple Oil biodiesel bends are used to the run thesingle cylinder four strokes diesel engine at different injection opening pressure. To optimize thethree opening pressure, Taguchi method adopted. For forming orthogonal array the experiments have been designed using DOE in Minitab 18 and Taguchi’s L9 array is employed. For identifying the contribution of various factors which significantly affects the response followed by regression analysis to validate the results at optimum set of selected control factors. This study deals with optimal values of BTE and NOx emission. From the results it reveals that NOx reduction is maximum at 200 bar injection pressure, B30 methyl ester blend at 50% load
