【摘要】 简述了世界上一些柴油车自由加速烟度排放法规。通过大量的试验研究,明确了柴油车自由加速烟度的排放机理,指出自由加速烟度排放的大小并不能真实反映柴油车实际行驶烟度的排放状况,因而自由加速烟度排放法规对改善柴油车实际行驶烟度排放的作用是非常有限的。更多还原

【Abstract】 Regulations on diesel vehicle free accelerating smoke emission around the world are introduced.Through a great number of experimental studies,the mechanism of diesel vehicle free accelerating smoke emission is found out,and it is pointed out that value of free accelerating smoke emission cannot reflect the actual driving smoke emission,so the regulation on free accelerating smoke emission only has limited effects on improving diesel vehicle actual driving smoke emission.更多还原
