Diesel-powered compression ignition (CI) engines use fossil fuels, which results in increasing greenhouse gas emissions and environmental pollution. Chicken fat, which is attributed to renewable fuels, is one of possible alternatives to diesel. This Article presents an experimental comparative research at various speeds (from 60 km/h to 90 km/h), replacing diesel with chicken fat at 30%, 50%, 70% and 100%. Cold chicken fat is highly viscous, so fuel was heated. Measurements of volumetric fuel consumption and the analysis of pollutant (CO2, HC, NOx and smoke) concentration in engine exhausts were performed revealing that fuel consumption increases with increasing chicken fat concentration in fuel, and the Brake Thermal Efficiency of the engine decreases. CO2 concentration increases, but HC and NOx concentration and smoke decrease. This is due to a change in the combustion process and the chemical composition of fuel having replaced diesel with chicken fat.
