In this study, the thermodynamic properties, energy release, combustion, and emission variations in a spark ignition (SI) engine fueled with alcohol-gasoline blends and gasoline has been investigated. Test results showed that the net indicated work area of alcohol-gasoline blends was wider than pure gasoline blends and also; this situation affected positively the brake mean effective pressure and engine power output. The mass burn ratio of alcohol-gasoline blends was higher than those of pure gasoline. The exhaust emission level decreased with the increase of ethanol content in the fuel blend, but similar results was not observed with methanol-gasoline blends.
