Abstract
This study investigates the fuel properties and emission characteristics of biodiesel derived from waste cooking oil (WCO) feedstock utilizing a novel CaO/CaFe2O4 composite catalyst. The biodiesel production process
involves transesterification, yielding a renewable and environmentally friendly fuel source. Fuel properties such
as density, kinematic viscosity, flash point, cetane number, and calorific value of the produced biodiesel and
its blends were determined and compared with the ASTM biodiesel standard. The chemical composition of
the fatty acid methyl ester of the produced biodiesel was confirmed with a Gas Chromatography-Mass Spectrometer and a Fourier Transformed Infrared Spectrometer was used to determine the functional groups and
chemical bonds present in the biodiesel. The characteristics of the exhaust emissions of the different blends of
biodiesel with petro-diesel (B20, B50, and B80) as well as pure biodiesel (B100) and petro-diesel (D100) were
evaluated through the exhaust gas emissions analysis at a constant speed of 1500 rpm in a four-stroke diesel
engine. Exhaust gas emissions such as carbon monoxide (CO), hydrocarbons (HC), carbon dioxide (CO2),
nitrogen oxides (NOX ), were measured. The results indicate that the WCO produced biodiesel meets the ASTM
standard specifications for these properties, showcasing its potential as a feasible alternative to petrodiesel.
Additionally, emission study results indicate that utilizing B20, B50, and B80 blends resulted in reduced CO, HC,
and CO2 emissions when compared to petro-diesel fuel amounting to (7.88, 25.29, and 31.26%), (9.24, 5.54,
and 27.85%) and (10.04, 6.02, and 21.96%) respectively. All biodiesels (blend or raw) emit more NOX than
petro-diesel
