Özet
Ethanol has the potential to be used as an alternative fuel to gasoline in the spark-ignited (SI) engines. In this study, ethanol was used as a fuel to reduce the fuel consumption and emissions and to improve the performance of a single cylinder SI engines. The tests were performed for a maximum torque speed (2500 rpm) and maximum engine speed (3250 rpm) at a wide open throttle (WOT) conditions. The results obtained from the use of ethanol gasoline fuel blends (E10, E20, E30, E40 containing 10%, 20%, 30%, 40% of ethanol by volume) were compared to unleaded gasoline fuel. The results indicated that when ethanol gasoline fuel blends were used, the engine torque, power and brake specific fuel consumption (BSFC) were increased; the exhaust gas temperature, the carbon monoxide (CO), carbon dioxide (CO2) and hydrocarbon (HC) emissions were decreased. Also, the flame speed was increased by presence of oxygen in the ethanol fuel molecule. Thus, process of combustion and stability were increased and engine efficiency was improved.
