| 摘要:在高压共轨电控柴油机上分别燃用柴油(D)、甲酯(B100)和生物乳化柴油(EB10、EB15和EB20)，进行ESC十三工况稳态测试循环试验，研究了生物乳化柴油中水和丁醇含量对发动机燃烧、动力性、经济性和排放的影响。结果表明:5种油品中EB10的放热率峰值最大;随着生物乳化柴油中丁醇和水掺混比例的增大，其滞燃期延长，燃烧持续期缩短；EB10的有效热效率高于柴油，燃油消耗率低于柴油，EB15和EB20与之相反。NOx、PM排放及烟度随水和丁醇掺混比例增大而降低，HC和 CO排放都有上升趋势但很微小；EB10、EB15和EB20的HC排放略高于柴油，CO排放低于柴油。 |

| Abstract:Diesel(D), methyl(B100) and emulsified biodiesel(EB10、EB15和EB20) were tested according to European Steady-State Cycle (ESC) test on a high-pressure common rail diesel engine.The effect of emulsified biodiesel with different water and butanol fractions on the characteristics of combustion, power performance, fuel economy and emission performance of the engine were investigated. The results show that the peak of heat release rate of EB10 is the highest, with the increase of water and butanol fractions in emulsified biodiesel, ignition delay increases, combustion duration decreases. The effective thermal efficiency of EB10 is higher than that of diesel and its BSFC is lower than that of diesel, but EB10 and EB15 have the opposite effect. NOx , PM and smoke decrease with increasing water and butanol content. HC and CO emissions raise but only raise a little. EB10, EB15 and EB20 have slightly higher HC emissions than diesel, and CO is lower. |
