摘要
在一台直列四缸汽油机上,研究了乙醇/汽油混合燃料对发动机性能的影响。结果表明在发动机结构、技术参数不变的条件下,动力性能在低转速下降低,高转速下升高,但变化幅度不大;燃油消耗率有所升高;排放性能明显改善。最后,通过模糊综合评价方法确定出最佳掺醇比。
In an inline four-cylinder gasoline engine, the influence of the mixed fuel of ethanol and gasoline on the performance of engine has been studied. The results show that dynamic performance of the engine is lower at a low speed and is higher at a high speed, when the structure and technical parameters of the engine remain unchanged, but modest changes; fuel consumption rate is increased; emission performance improves obviously. At last, the best-mixed ethanol rate is identified by vague comprehensive evaluation method.
