• The results show that DME operation has longer injection delay, lower maximum cylinder pressure, lower ratio of pressure rise, shorter ignition delay in comparison with diesel operation.

    结果表明柴油相比发动机燃用二甲醚时的喷油延迟延长燃期缩短最高爆发压力和最大压力升高均低于柴油机。

  • With increase of bed height, air pressure and power consumption rise, expansion ratio of the bed decreases, but the density stability and critical fluidized velocity of the bed are hardly changed.

    随着高度增加,所需风压功率增大膨胀有所降低床层密度稳定性起始流化气几乎不变。
