Optimisation of energy and exergy parameters of a C.I. engine in dual fuel mode using Taguchi method

Abstract

In this study, the first and second laws of thermodynamics are applied to analyse the quantity and quality of energy and exergy in a compression ignition (C.I.) engine using diesel and biogas in dual fuel mode. The energy and exergy for the engine have been calculated and analysed by Taguchi method for both modes of operation using MINITAB software. The results show the similar energetic performance of dual fuel mode as that of diesel fuel mode. The exergetic performance parameters also follow the similar trends according to the energetic performance parameters. The analyses are based on energy and exergy distribution of dual fuel mode with the varying load and compared with the corresponding values of diesel mode.
