分析了有效燃油消耗率及各主要排放污染物( nox 、 pm 、 co 、 hc 、碳烟)的排放量随运转参数(转速n与平均有效压力p _ ( me ) )的变化规律。指出nox与pm是影响增压中冷柴油机排放达标的主要排放污染物，并绘制了排放综合特性图。这为该类型柴油机的性能分析提供了参考。 |
| 8. | In this paper , the author introduces another experimental research on dpf regeneration , which has been conducted by spraying h2o2 into the filter . it features that the temperature at which the soot oxidizes properly by the reaction between carbon and highly active radical species generated from h _ 2o _ 2 become much lower
本文采用了一种新的方法对柴油机微粒过滤器的再生进行了试验研究，即利用h _ 2o _ 2分解产生的活性基团和碳烟进行反应，从而在较低的温度下将碳烟烧掉。 |
| 9. | The results of the experiments has shown : the lpg / diesel dual fuel engine has kept its high power performance and reduced its emissions , especially the soot and nox after the fuel - supplied system has been set up ; the fuel economy performance has been improved at some degree when high load ; however , when lpg ratio increased , the engine showed the trend of violence for high compression ratio
试验结果表明：在采用了自行设计的联动式燃油供给系统后， lpg柴油双燃料发动机在保持原机高功率的同时，排放量，尤其是碳烟和no _ x有大幅度的降低；在高负荷时，其燃油经济性也有相当的提高。但当lpg的掺烧比加大到50以上时，会出现工作粗暴的倾向。 |
