Parametric optimization of a direct injection ‐ compression ignition engine fuelled with butanol/diesel blend using response surface methodology

This paper presents results of a simulation study on the performance and emission characteristics of a direct injection compression ignition engine, fuelled with butanol/diesel blend (20% of butanol‐by volume, called as Bu20). The aim of this study is identify optimum values of the engine operating parameters for this Bu20 fuel, which give the best performance with minimum emissions. CONVERGE CFD software was used to carry‐out the simulation...
