In this study, three different fuels named G100 (pure gasoline), E20 (volume 20% ethanol and 80% gasoline blend) and ES20 (20% sodium borohydride added ethanol solution and 80% gasoline) were used to test in a gasoline engine. First of all, G100 fuel, E20 and ES20 blended fuels, respectively, were tested in a gasoline engine and the effects of fuels on engine performance and exhaust emissions were investigated experimentally. Experiments were carried out at full load and at five different engine speeds ranging from 1400 to 3000 rpm, and engine performance and exhaust emission values were determined for each test fuel. When the test results of the engine operated with E20 and ES20 blended fuels are compared with the test results of the engine operated with gasoline; engine torque of E20 blended fuel increased by 1.87% compared to pure gasoline, while engine torque of ES20 blended fuel decreased by 1.64%. However, the engine power of E20 and ES20 blended fuels decreased by 2.02% and 5.10%, respectively, compared to the power of pure gasoline engine, while their specific fuel consumption increased by 5.02% and 6.57%, respectively, compared to pure gasoline fueled engine. On the other hand, CO and HC emissions of the engine operated with E20 and ES20 blended fuels decreased compared to the pure gasoline engine, while CO2 and NOx emissions increased.
