Investigation on the Droplet Combustion Behaviour of Palm Biodiesel-graphite Oxide Blends

The toxic emissions from diesel fuel are contributing to the environmental issues such as greenhouse effect and air pollution. Toxic emissions are nitrogen oxides (NOx), particulate matter (PM), carbon monoxide (CO), unburnt hydrocarbons (UHCs) and so on. Blended biodiesel can be an alternative fuel...
