Optimization of Diesel Engine Parameters of Performance and Emission by Taguchi Method

Abstract
The present work discus the Taguchi technique to determine the optimum engine parameters at which the diesel engine works effectively fuelled with diesel-biodiesel-ethanol (Ternary fuel) blends operating with different injection opening pressure, 180 bar, 200 bar and 220 bar. The three different Ternary fuel blends were used, B20, B30 and B40. In this technique L9 array is selected and three factors like IOP, Blend and load are analyzed. It was found that 200 bar IOP, B30 and 80% load are the optimum parameters at which DI diesel engine operates effectively. Experiment was conducted with the optimum parameters. The predicted values of brake thermal efficiency (BTE), brake specific fuel consumption (BSFC), exhaust gas temperature (EGT), carbon monoxide(CO), carbon dioxide (CO2), hydrocarbon (HC), and oxides of nitrogen (NO) are comparable with experimental results. Keywords - Taguchi Method, Ternary Fuel Blend, Optimum Parameters.
