摘　　要：我国排放标准的计划升级速度明显快于欧洲,准备用10年时间完成欧洲16年的升级历程（升级到国Ⅴ）。实际上,我国从国Ⅱ升级到国Ⅲ、国Ⅳ分别用了8年和13年,和欧洲标准第2阶段升级到欧Ⅲ、欧Ⅳ时间相同。最近十几年,商用车发动机排放升级让用户应接不暇,大部分用户都是被动接受,对于排放标准的制定依据、排放物限值等并不是很清楚。从本期开始,我们就针对这些话题和大家探讨一下商用车柴油机排放污染物限值和相应技术的发展情况。In the past few year s, t he emission standard of commercial vehicle engine has been gradually raised, which had made most engine producers passively follow the regulations without understanding and knowing exactly the rules and limitation of these standards. From this issue, the <Commercial Vehicle> magazine will conduct a series of review and discussions about the issue of emission limit and current development of relevant technologies.
