The Effect of Gasoline/1-Butanol Blends on Spark-Ignition Engine Performance


Article Preview

Butanol has been considered an attractive alternative fuel for automotive engine. In the present study, a numerical study is conducted in a spark-ignition engine fuelled with blends of gasoline and 1-butanol at different fuel/air equivalence ratios. The effect of fuel/air equivalence ratio on engine performance is analyzed. The results show that the peak pressure and peak temperature increases with the increasing of fuel/air equivalence ratio. With increased 1-butanol proportion, the incylinder pressure and incylinder temperature gradually decreases. In addition, effect of fuel/air equivalence ratio on nitrogen monoxide emission is depended on the proportion of 1-butanol in blended fuels.
