Abstract
Mahua oil ethyl ester was prepared from mahua oil using potassium hydroxide as catalyst by trans-esterification. The important fuel properties of mahua biodiesel blends were compared with those of high speed diesel and biodiesel standards. Variation of brake specific fuel consumption (BSFC), brake thermal efficiency (BTE), Pmax, CO, NOx, hydrocarbons, and smoke opacity across compression ratio, blending ratio and load were studied successfully using response surface methodology based on Central composite rotatable design. The trends similar to general theory of compression ignition engines (CI) were obtained. Optimum performance and emission parameters were determined by considering the significant variables affecting the diesel engine. Significant reduction in emissions at 23% blending ratio were observed as compared to neat diesel at optimum input variables. Hence mahua biodiesel is an environment friendly alternate fuel over diesel and has good scope to run the compression ignition engines.
