摘要
在一台单缸柴油机上利用TSI 3090 EEPS(发动机排气粒径分析仪)测量不同空燃比下柴油机尾气颗粒物粒径分布。结果表明:随着空燃比的降低,颗粒物数量浓度、质量浓度、表面积浓度和体积浓度随之增大,粒径分布向大直径粒子方向偏移,核态粒子减少,积聚态粒子增加。
Exhaust particle size distributions were measured using TSI 3090 EEPS on a single cylinder diesel engine under different air fuel ratios. The results indicate that the number concentration, mass concentration, surface area concentration, volume concentration distribution increase with the decrease of air fuel ratio. Size distribution moves to the bigger diameter direction. The nuclei mode particle has a slight decrease, Accumulative particulate increases.
