| 摘 要： | 在一YC6J170-21车用六缸发动机上进行了添加助溶剂（正丁醇）情况下,无水乙醇与市售0#柴油的混合燃料对柴油机经济性和排放特性影响的研究。试验结果表明：柴油机燃用乙醇柴油混合燃料的油耗率比纯柴油高,并且随乙醇比例的增大油耗率增大,但混合燃料的等热值当量油耗率与纯柴油相差不大,混合燃料的有效热效率比纯柴油高。柴油机燃用乙醇柴油混合燃料后,NOx和碳烟排放大幅度降低,且随着混合燃料中乙醇比例的增加,下降效果明显。柴油机燃用乙醇柴油混合燃料对CO的排放改善不明显,CO排放与原机相当。柴油机燃用乙醇柴油混合燃料后,HC排放比原机增大,且HC排放与混合燃料中乙醇比例及发动机工况有关,乙醇比例越高,HC排放也基本越大。

| Abstract: | Ethanol and 0# diesel are mixed with solutizer,the effect of the mixing fuel on economy and emission characteristics of YC6J170-21 vehicle using 6-cylinder diesel engine is studied.Results show that: compared with pure diesel,fuel consumption rate of ethanol-diesel blended fuel is relatively high,and it increases as ethanol increases,but the equal-caloric value equivalent fuel consumption rate of mixing fuel has little difference with pure diesel.Effective fuel efficiency of mixing fuel is higher than pure ... |
