This document summarizes research into designing an eco-friendly gasoline engine that uses biogasoline to conserve energy. The researchers tested blending methanol with gasoline in ratios of 30-70% and 20-80% in a variable compression ratio engine. They found that using a 20% methanol blend reduced fuel consumption and lowered emissions of hydrocarbons, carbon monoxide, carbon dioxide, and nitrogen oxides compared to gasoline alone. The methanol blend also improved the engine's performance. Therefore, the researchers concluded that a 20% methanol-gasoline blend can be an effective alternative fuel that reduces emissions and fuel use while helping address future gasoline shortages.
