| 摘 要： | 针对1台大排量电控高压共轨柴油机,在发动机结构和参数不作变动和调整的条件下,研究了5种不同生物柴油含量的混合燃料(B0,B10,B15,B20和B30)对发动机燃烧特性的影响。结果表明,随着燃料中生物柴油含量的增加,燃烧始点、燃烧终点、放热重心逐渐提前,滞燃期和燃烧持续期有所缩短,发动机的缸内最高燃烧压力和放热率峰值逐渐降低,所对应的相位逐渐提前。生物柴油含量对缸内最高燃烧压力影响较小,而对放热率峰值影响较大,在大负荷工况下对放热率的影响更加明显。

| Abstract: | For an electronic-controlled high pressure common rail diesel engine,the influences of five diesel/biodiesel blends,which were B0,B10,B15,B20 and B30,were studied respectively on the same engine.The results show that the combustion beginning,combustion termination and heat release centre advanced with the increase of biodiesel fraction,while the ignition delay period and combustion duration shortened.When the fraction of biodiesel increased,the pressure in the cylinder and the peak value of heat release dec... |
