Influence of Gasoline-Methanol Mixtures in a Two-Stroke Engine

Abstract: 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.
