Biofuel has been discovered as alternative fuel due to potential of being environmentally friendly. Experimental analysis is limited by high cost, time, and evaluation of engine parameters. This study has numerically investigated potentials of biofuel blends as alternative to diesel fuel in terms of reduction in emissions of NOx, and CO using MATLAB interface. Test engine was chosen and various biodiesels were identified. Developed models were used to obtain various emission characteristics in respect to each of the biodiesels at various blends. Three biodiesels (Jatropha, Waste cooking oil (WCO) and Algae) were explored and investigated with relative increase in NOx emission and ranges from Waste Cooking Oil, Jatropha and Algae as 0.0013, 0.0014 to 0.0015 in increasing order respectively at B20 blends of each of the biodiesels. Respective CO emission reduction in Waste Cooking Oil, Jatropha and Algae with values, 0.0064, 0.0091 and 0.0085 in order for B20 blends of each of the biodiesel. For all the emission gases with better properties using biodiesel, significant decrease occurred at lower blends. The study revealed that blend of B20 Waste Cooking Oil biodiesel is environmentally suitable as biofuel for combustion in diesel engine.
