部分AdBlue加注站停用：北京国IV公交加注尿素需靠人工

Some AdBlue Refill Stations for Public Buses Are Suspended

随着北京八方达公司的亚星YBL6985和京华BK698081型城市客车的“退休”，以及新车型陆续上路，北京公交基本告别了国Ⅱ公交时代，而代替它们的将是符合国Ⅲ甚至国Ⅳ排放标准的新型城市客车。

Currently, most public buses in Beijing have to be regularly refilled with AdBlue for purpose of meeting the emission level of National Standard Ⅳ. The author found, based on his survey, that though Beijing Public Transport Holdings Ltd has many AdBlue Refill Stations located in public bus terminals and parking stations, most of them have been suspended. This is the author’s analytical report of the survey.
