| 摘 要： | 研究了乙烯-醋酸乙烯酯共聚物(EVA)作为含氧燃料添加剂对燃料性质、柴油机性能和排放的影响。在同一台内燃机车上分别用纯柴油和加0．1％EVA的柴油样品试验，并测定了发动机性能、燃烧特性和各种有害排放物的浓度。结果表明，EVA对降低内燃机排放中的HC、CO化合物和碳烟等有害物质，特别是降低碳烟、HC排放作用显著，随着柴油机负荷增加，碳烟、HC排放浓度降低幅度增大。 |

| Abstract: | To reveal the effects of ethylene-vinyl acetate (EVA) copolymer, as a fuel additive, on engine performances and emissions, the tests on the performance, combustion property and pollution emissions of an engine were carried out. The results show that with 0 1% EVA as additive in diesel oil can remarkably reduce the emissions of hydrocarbon (HC), exhaust smoke and carbon monoxide (CO), especially the first two. As increase of the engine load, the concentrations of HC and exhaust smoke will decrease; when the engine runs at a low load, the reduction extents of these emissions will get smaller. |
