Abstract: An experimental study of the measurement of performance parameters of a single cylinder four stroke diesel engine using diesel fuel produced in Iraq and blended with ethanol was carried out. The test fuels were used in this study included E0 Beji (100 % diesel Beji fuel), E0 Basra (100 % diesel Basra fuel), E0 Daura (100 % diesel Daura fuel), E8 blended (8% ethanol and 92% diesel Basra fuel in vol.), and E10 blended (10% ethanol and 90% diesel Basra fuel in vol.). The experimental measurements were performed at compression ratio of 22.5 at engine speed ranging from 1100 to 2600 rpm with an increment of 500 rpm, and engine torque ranging from 2 to 10 N.m with an increment of 2 N.m. Brake specific fuel consumption, brake thermal efficiency, brake power, mechanical efficiency, brake mean effective pressure and exhaust gas temperature were studied in this research. The experimental data from engine during test have been saved on the computerized program (ECA 100, VDAS) connected to the unit.The results show that the E8 blended fuel type registered the high value of brake specific fuel consumption .There were about 28.02 % for E8 blended fuel, 20.88 % E0 Beji fuel, 19.2 % for E0 Basra fuel, and 8.24% for E10 blended fuel higher of brake specific fuel consumption than that E0 Daura fuel. E0 Daura fuel type registered the high value of brake thermal efficiency followed by E0 Basra, E10 blended, and other types. E0 Daura fuel type recorded the high value of mechanical efficiency. E10 slightly recorded the higher value of brake mean effective pressure for all torques and speeds. E0 Basra diesel fuel gives higher exhaust gas temperature for all torques and speeds.
