One of the alternative fuels that are used is methanol. Methanol (CH3OH) is an alcohol that is produced from natural gas, biomass, coal and also municipal solid wastes and sewage. It is quite corrosive and poisonous and has lower volatility compared to gasoline, which means that is not instantly flammable. Usually methanol is used as a gasoline-blending compound, but it can be used directly as an automobile fuel with some modifications of the automobile engine.
This paper refers to the use of gasoline-methanol mixtures in a two-stroke small engine. The mixtures that were used are: gasoline, gasoline-10%methanol 20%methanol, gasoline-30%methanol, without any regulation of the engine relatively to the air/fuel ratio, maintaining the original adjustment that concerned gasoline was maintained. An important reduction of emission(CO, HC) was noted while the percentage of the methanol was increased. During the tests the fuel consumption was recorded for every mixture separately. It was observed a small increase of consumption when the percentage of methanol in the fuel was increased.
