Abstract

In this study, the availability of methanol instead of ethanol was investigated in terms of performance, emission and combustion characteristics. The experiments were conducted in a single cylinder, four-stroke SI engine for different engine speeds at full engine load. Test fuels were prepared by 10% ethanol and methanol addition into gasoline. According to the experimental results, while methanol addition increased bsfc values by 10.3% compared to ethanol addition, it caused a reduction to the bte values by 6.12%. The methanol addition fuel has shown similar combustion characteristics with ethanol addition fuel. Although the methanol addition decreased CO2, CO, HC and NOx emissions by 6.48%, 26.6%, 4.75% and 9.16% respectively compared to ethanol addition, it has higher oxygen emission values by 15.3% due to its higher oxygen content than ethanol. These results show that methanol can also use as an additive for gasoline like ethanol.
