Abstract

Biodiesel was extracted from three different individual sources: waste frying oil, palm oil, and castor oil to find out if significant differences exist among biodiesel fuels within their thermo-physical properties and engine performance characteristics and the resulted exhaust emissions. The study investigated the effect of these biodiesels properties on engine performance characteristics,to determine the appropriate biodiesel source for best engine performance. The tested properties were: kinematic viscosity, density, flash point, heat value, and pour point. The tested exhaust emissions elements were: Oxygen, Sulfur dioxide, Carbon dioxide, Carbon monoxide, and Nitrogen oxides. Engine performance characteristics under evaluation were Brake power, Brake specific fuel consumption, and the Air fuel ratio.
