Abstract: Aligning to water-in-diesel emulsion technology, a newer work has been proposed in this study by introducing gomutra-in-diesel emulsion (GMD emulsion) fuel for application in CI engine. Experimental investigations have been performed in this study for ignition delay and combustion duration to understand the underlying mechanisms of combustion with this fuel. The complete work has been performed over a variable compression ratio (VCR) stationary diesel engine. Emulsions of different gomutra-in-diesel (5%, 10%, 15% and 20%) concentrations were taken for the study. The ignition delay was found to be 24°, 27°, 29°, 32°, and 34° crank angle (CA) with diesel, 5%, 10%, 15%, and 20% water-in-diesel emulsions respectively. The effect of injection timing on the engine performance was also analysed. It was observed that the combustion duration got decreased by a maximum of 12 degrees CA with 20% GMD emulsion. It is estimated that after the optimisation of other engine parameters like injection pressure and compression ratio, the performance of the engine could further be improved.
