This study is focused on recycling used cooking oil from residential dwellings and making it a promising alternative to fossil fuel, where the collected oil is converted into biodiesel and tested on a diesel engine rig. The fuel consumption of biodiesel is slightly higher compared with standard diesel because of the lower heating value of the biodiesel, higher viscosity, and density. Lower emissions of carbon monoxide and hydrocarbons have been observed in biodiesel compared with diesel fuel, whereas the carbon dioxide emissions were almost the same for both fuels. Nitrogen oxides emissions were observed to be higher compared with diesel because of higher oxygen content in biodiesel, short ignition delay, and advances in injection and combustion of the engines.
