An experimental investigation of the combustion of various kerosene-diesel and alcohol-diesel fuel blends is presented. Tests are conducted in a continuous flow combustor to study the effect of fuel blends on the combustion process and pollutants in the exhaust gases. Exhaust analyses of CO, CO2, O-2, NOx, HC and soot mass concentration are presented. For the ethanol-alcohol-diesel blends, a stabilizer (isobutanol) is added to the mixture to improve and maintain miscibility.
