This study investigates the effect of the injection pressure on the spray characteristics and atomization of the fuel. The novelty of the work lies in examining the injection pressure (IP) at four different scenarios such as 180 MPa, 200 MPa, 220 MPa and 240 MPa. A series of test conducted in the single cylinder engine at three different concentrations of B10 (5% Jatropha curcas and 5% Thevetia peruviana-50 ppm of Fe2O3), B20 (5% Jatropha curcas and 5% Thevetia peruviana-50 ppm of Fe2O3) and B30 (5% Jatropha curcas and 5% Thevetia peruviana-50 ppm of Fe2O3). All the samples were tested for performance and emission characteristics. Based on the procured results, the combination of the dual biodiesel blends improvised the production of higher brake power and lowered specific fuel consumption. Adding two blends together reduced the overall viscosity of the Thevetia peruviana (yellow oleander oil) since the viscosity of the jatropha is lower than the yellow oleander oil. As the concentration of the blends is increased there is a marginal drop in the brake thermal efficiency, however there is an improvement in the brake specific fuel consumptions. In terms of the combustion efficiency, the heat release rates were improvised upon addition of Fe2O3. With regard to the emissions, there is no significant change in the NOx. Nevertheless, there is a drastic reduction in the HC and CO formation has been witnessed. Among various blends, B30 at 240 MPa of IP reported lower emissions than B10 and B20. In order to examine the fuel atomization and spray characteristics, numerical modelling was applied. At 240 MPa, the fuel mixing rates were higher compared to the other injection pressure
