| 摘 要： | 进行了丙二醇单丙醚(PGPE)/乙二醇二甲醚(EGDE)混合物用作柴油机含氧燃料的研究,对比了柴油机燃用柴油、PGPE/EGDE体积分数分别为15%和25%的混合燃料时的燃烧和排放特性。试验表明PGPE/EGDE混合燃料的燃烧特性与0号柴油相比,滞燃期、燃烧持续期和热效率等差异较小,最高燃烧压力小幅下降;显著降低柴油机中高负荷时的碳烟和CO排放,降幅分别可达73.9%和37.5%,NOx排放无显著变化,但HC排放增加。 |
| 关 键 词： | 柴油机 含氧燃料 混合燃料 燃烧性能 排放 |

| Abstract: | The blends of propylene glycol monopropyl ether (PGPE) and ethylene glycol dimethyl ether (EGDE) used as oxygenated fuel blends were researched,and the comparisons of combustion and emission characteristics for diesel engine fueled with 0# diesel and PGPE/EGDE blend fuels whose volume fractions were 15% and 25% respectively were made.The results showed that,the ignition delay period,combustion duration and brake thermal efficiency weren't changed obviously,the maximumin-cylinder pressure was slightly decreased,the soot and COemissions were obviously reduced by 73.9% and 37.5% respectively at the mediumand high loads,the NOxemission wasn't increased or decreased,and the HC emission was increased when the engine was fueled with PGPE/EGDE blend fuels. |
| Keywords: | diesel engine oxygenated fuel blend fuel combustion performance emission |
