In this study, the effect of methanol or butanol addition to gasoline on exhaust emissions and noise level has been experimentally investigated. Results showed that the concentrations of CO and NO(x) emissions were decreased depending on the higher alcohol contents and the carbon monoxide concentration of gasoline was higher than that of methanol or butanol-gasoline blends for all engine loads. It was determined that content of the HC was decreased at higher engine load but noise level was increased.
