| 8. | The mechanism of fuel saving and emission reduction were discussed in this paper . based on surface chemistry , proper emulsifiers were selected to produce stable emulsified diesel oil , which contains different amount of water . the characters of emulsified fuel such as viscosity , heat value and factors in connect with stability were analyzed 本文以利用乳化油减少柴油机燃油耗和降低排气污染为主要目标,先从理论上分析了乳化油节能和降低排放的机理,然后利用表面化学的知识筛选出适当的表面活性剂,复配出高效的复合型乳化剂并用其配制出不同掺水率的稳定的乳化柴油,对乳化油的物性(粘度、热值等)及影响乳化油稳定性的因素进行了分析。 |
| 9. | When the water dose was 20 % and engine speed was 2000r / min , the maximum fuel saving was 4 . 1 % ; the thermal efficiency of emulsified fuels was higher than that of using pure diesel oil . nox and particulates emissions were reduced greatly by using emulsified fuels . when water dose was 20 % and engine speed was 1500 r / min , the maximum nox reduction was 43 . 4 % ; the average of particulates under all loads was reduced by the extent of 46 % ~ 64 % 结果表明:燃用乳化油节油率有所提高,当n = 2000r min ,掺水率为20时最大节油率可达4 . 1 ;燃用乳化油的热效率也高于燃用纯柴油; no _ x 、颗粒排放比燃用纯柴油时则有大幅度降低,当n = 1500r min掺水率为20时, no _ x排放量下降的最大值可达43 . 4 ;固体颗粒物排放量在整个负荷范围内的平均值比燃用纯柴油时低46 64 ;随着乳化油掺水量的提高,排放效果改善越明显;而thc和co的排放量则比燃用纯柴油时有所升高。 |
