Abstract: An experiment was executed at internal combustion engines laboratory/ Institute of Technology Baghdad – Middle Technical University to evaluate the performance and emission of a single-cylinder, four-stroke naturally aspired gasoline engine. The tested engine was fueled by four types of fuel: imported gasoline (A1), Al-Shuaiba refinery gasoline (A2), AlDora refinery gasoline (A3), and Al-Nasiriyah refinery gasoline (A4). The engine was operated within three levels of speed 1500, 2000 and 2500rpm under three levels of torques 2, 4 and 6Nm. The engine exhaust emissions which include oxygen gas (O2), carbon monoxide (CO), carbon dioxide (CO2), nitrogen oxides (NOx) and unburned hydrocarbons (HC) were measured using a gas analyzer device and smoke meter. The experimental results were statistically analyzed using the Split-Split plot design and SAS (2012) software based on a complete randomized design (CRD) within three replications. The least significant differences (L.S.D = 0.05) under probability of 0.05 was utilized to compare the means of treatments. The results show that the lowest value of O2 that was 20.1% was recorded within the A1 while this gas increased to be 22.95% by using A4. The value of CO with A1 decreased to be 0.1% while it raised to be 6.21% with A4. The CO2 increased within A1 to be 20.11% whereas it declined with A4 to be 11.26%. The rates of HC and NOx decreased within A1 to be 39 and 275.7 parts per million (ppm); however, they increased by using A4 to be 341 and 2393.3 ppm, respectively.
