摘要: The main aim of this study is to investigate the performance and pollutant emissions a four stroke SI engine operating on different ethanol-gasoline blends (0-20%). Fuel properties ethanol–gasoline blended were examined by standard ASTM methods. results showed that increasing ethanol content in blend fuel will decrease heating value increase octane number. Exhaust gas evaluated analyzed for Unburned Hydrocarbons (UHC), Carbon Dioxide (CO 2 ), Monoxide (CO), Oxygen (O ) Oxide Nitrogen NO x at speeds loads (1000-5000 rpm). revealed using fuels marginally brake power torque output, thermal efficiency, relative air–fuel ratio volumetric efficiency. Moreover, specific consumption, CO HC concentration. This improvement was due high oxygen percentage ethanol. However , concentration exhaust temperature noticed be increased.
