Continued use of petroleum sourced fuels is now broadly recognized as unsustainable because of the decreasing supplies and the contribution of these fuels to the addition of carbon dioxide and carbon monoxide in the environment. Renewable, carbon neutral, transport fuels are essential for environmental and economic sustainability. Here we will contrast the original fuel with the blends of biodiesel obtained by two stage trans-esterification method from neem oil to evaluate the performance and emission characteristics of diesel engine. The obtained bio diesel is mixed with original fuel in a variety of ratios, including B25 percent, B50 percent, B75 percent, and B100 percent. The reason for choosing different mixes is that they gives different readings from which the engine performance and other operational parameters can be evaluated. Metal-based nano additives have an impact on diesel engine performance and emissions. Iron oxide nanoparticles have been chosen as a biodiesel addition. The experiment was carried out in a single cylinder water cooled diesel engine with neem oil as the sole fuel, and the engine performance and emissions were measured and analysed. The CO, NOx emission are found to decreases for all the biodiesel blend with decrease in smoke emission when compared to that of diesel fuel.
