The Influence of Ethanol–Gasoline Blends on Performance Characteristics of Engine Generator Set

چکیده
The aim of this research is to study the influence of using ethanol-gasoline fuel blends on spark ignition engine performance characteristics and compare the obtained results with those using base gasoline. An electric generator operated by a SI (spark ignition, four stroke, single cylinder, air cooled) engine was used for conducting this study. The tested fuels were gasoline (E0) and gasoline-ethanol blends (E5, E10, & E15). The test was conducted at a constant speed of 3000 revolutions per minute (rpm) under varying electric loading conditions. The experimental results revealed that with the use of ethanol-gasoline blends, the overall efficiency of the engine -generator set and exhaust gas temperature increased while total fuel consumption and specific fuel consumption showed a trend of decreasing. Finally, the E15 blend showed a comparatively good performance compared with that of base gasoline.
