丁醇-汽油混合燃料应用于汽油机的性能实验研究

Performance experiment of N-butanol-gasoline blending fuel applied gasoline engine

本文对不同比例的丁醇-汽油混合燃料在气道电控喷射汽油机台架上进行了性能实验研究。在转速为2 000 r/min和2 500 r/min时,将分别添加体积分数10%、20%丁醇的混合汽油与纯汽油进行了对比。研究结果表明,掺混丁醇后,发动机动力性略有下降,有效燃油消耗率略有增加,在90 N·m时比油耗取得最低值,在实验工况下HC和NOx排放略有下降,对CO影响较小。

We conducted performance experiment for blending fuel of different blending ratios of n-butanol and gasoline applied port fuel injection engine. We compared pure gasoline and the blending fuel of blending ratios of 10% and 20% for 2 000 r/min and 2 500 r/min. Results show that the power of the engine slightly falls and BSFC increases a little. Specific fuel consumption is the lowest for torque moment of 90 N · m. For experimental condition, HC and NOx emission slightly decreases. The effect on CO emission is less.
