| 摘 要： | 研究了含氧燃料添加剂对柴油机微粒排放的影响。利用静电微粒筛选器和动力微粒筛选器对燃烧不同比例氧化燃料添加剂的柴油机废气中的微粒分布进行了测量。同时，还分别利用红外气体分析仪、火焰离子探测器和化学发光分析仪对相同样气中的一氧化碳、碳氢和氮氧化物的排放特性也进行了测量。研究表明含氧燃料添加剂对柴油机微粒的分布有影响，它能显著地降低碳烟的排放，而对一氧化碳、碳氢和氮氧化物的排放影响不大。

| Abstract: | The effect of oxygenated additive on particle emission is investigated. Particle size distributions in exhausts from a diesel engine fueled by the blended fuel with different proportions of oxygenated additive are measured by a scanning mobility particle sizer and an aerodynamic particle sizer. Coupled with this, emissions of carbon monoxide, hydrocarbon and nitrogen oxide are also measured with an infrared analyzer, a flame ionization detector and a chemiluminescent analyzer respectively. Results show that there is an effect of oxygenated additive on the particle size distribution from diesel engine. Oxygenated additive can significantly reduce particle emission level and slightly modify emission concentrations of carbon monoxide , hydrocarbon and nitrogen oxide. |
