| 摘 要： | 利用异辛烷与正庚烷配比不同辛烷值燃料,在快速压缩机上进行可控自燃(CAI)燃烧试验,研究了不同边界条件下燃料辛烷值对CAI燃烧特性的影响规律。结果表明,在其他边界条件不变的情况下,随着燃料辛烷值的增加,最大压力升高率降低,最大压力升高率出现时刻延迟,燃烧温度开始迅速上升的时刻延迟,燃烧温度的最大值减小,燃烧始点延迟,燃烧持续期延长。 |
| 关 键 词： | 内燃机 辛烷值 可控自燃 燃烧特性 快速压缩机 |

| Abstract: | The fuel with different octane numbers was acquired by mixing iso-octane and heptane.On a rapid compression machine,the controlled auto ignition(CAI) test was carried out and the influences of fuel octane number on CAI combustion were studied under different boundary conditions.The results show that,with the increase of octane number,the maximum rate of pressure rise decreases and its corresponding timing delays.In addition,the timing of rapid rise for combustion temperature delays,the highest combustion temperature decreases,the timing of combustion delays and the combustion duration extends. |
| Keywords: | internal combustion engine octane number CAI combustion characteristic rapid combustion machine |
