To estimate the performance, combustion with emissions characteristic of CI engine powered by diesel with biofuel blend formed from fish processing by-products, the experimental method was used to examine the impact of titanium oxide metal based additives on engine operation with varying titanium oxide concentrations in the biodiesel blends. The fish biofuel was obtained by the fish oil from transesterification method. The titanium oxide additives were combined with the fish biodiesel suspension fuel at changed concentration of 80ppm, 100ppm and 120ppm respectively. The whole experimental investigation was directed in diesel engine by means of 3 different fuels, viz., diesel, fish oil methyl ester and titanium oxide blended fish oil methyl esters. Experimental outcomes discovered that, the performance characteristics like BTE and BSEC. Marginal enhancement in the BTE for the titanium oxide blended fish oil methyl esters (FOME) compared with neat diesel and FOMEB20 with lower BSEC. The concentration of 75ppm of cerium oxide shows the improved combustion characteristics of HRR and peak pressure compare to diesel and FOMEB20. Substantial drop in CO, UBHC and reduction in NOx emission are accomplished with FOMEB20 biofuel blend. But there is a substantial drop in CO and UBHC emission for B20 biofuel blend with titanium oxide as an enhancer associated along FOMEB20 biofuels blends and diesel. The titanium oxide blended biodiesel fuel shows the lower NOx emission compare to FOMEB20 fuel. The smoke opacity also reduced for the blend with titanium oxide fuel compare to diesel and FOMEB20.
