Summary:Alternative fuels for use in internal combustion engines have become recently in attention due the strict regulations regarding the environmental protection, emissions and to reduce the dependency of the fossil fuels. One choice is the use of methanol as it can be produce from renewable sources and blended with gasoline in any proportion. The aim of this study is to compare the effects of methanol - gasoline blends regarding performance, combustion and emission characteristics with gasoline. Five different blends M5, M10, M15, M20 and M25 were tested in a single cylinder spark ignition engine typically used in scooters applications. The experimental results in engine performance show a decrease of torque and power up to 10 %and in emissions characteristics a CO, CO2, HC. It can be concluded that gasohol is viable option to be used in gasoline engines to replace partially the fossil fuel.
