【 摘 要 】

The main objective of the present work was to reduce the higher NOx emission of a stationary engine fueled with diesel with less increase in smoke density and compare the results with that of crude rice bran oil methyl ester (CRBME). Design of experiments method was employed to design the experiments and Taguchi’s L9 orthogonal array was used to conduct the engine tests. Experiment results were analyzed by calculating multi response signal-to-noise ratio (MRSN) and the optimum combination level of factors for the chosen objective was obtained simultaneously using Taguchi’s parametric design. Variance of the MRSN ratio was analyzed through analysis of variance method and the most influencing factor for the chosen objective was obtained for diesel and compared with CRBME. Confirmation experiment was conducted for the obtained optimum combination level of factors and the results were compared with normal operating conditions.
