This study investigates the combustion, emissions, and performance of biodiesel produced from poultry fat FAME (fatty acid methyl esters) in an indirect injection (IDI) engine. The poultry fat FAME blends were evaluated against ultra-low sulfur diesel #2 (ULSD#2) at 2600 rpm at 100% engine load. The tested biodiesel blends of poultry fat FAME included B20 to B50 measured by weight percentage in ULSD#2. Before engine testing, the energy content, dynamic viscosity, and thermal properties were measured for all poultry fat blends, 100% poultry fat FAME, and ULSD#2. Once the preliminary data had been obtained, it was determined that a blend of up to 50% poultry fat FAME would be within ASTM6751 requirements. The ignition delay stayed constant at 13 CAD for all blends tested and the gross heat release for ULSD#2 and B50 were 24.4 and 25.0 J/deg respectively.
