Abstract: In the present theoretical study, a comparative performance analysis of a single cylinder compression ignition engine with diesel, 5% and 10% water in diesel emulsion as fuels have been investigated. Effect of variation in engine operating parameters like inlet pressure, friction coefficient compression ratio, equivalence ratio, and a residual gas fraction on engine performance parameters, i.e., effective power, effective power density, and total heat loss have been analyzed. Analysis has been carried out on the basis of isobaric heat addition and isochoric heat rejection assumptions with temperature variable specific heats and composition of alternative fuels. Microexplosion phenomenon for secondary atomization in water in diesel emulsion fuels improves the fuel combustion efficiency for better performance.
