王意宝是潍柴动力技术中心后处理技术研究室的一名工程师,主要从事后处理技术的研究。在他看来,国Ⅳ标准的实施,在油品和尿素供应两大问题中,保证卡车的尿素供应更为重要。从目前国家储备和产量看,尿素产能问题不大,主要是尿素加注站的普及。“目前公交车的尿素加注站建设相对容易,但真正实施国Ⅳ后,分布更广、运行更分散的卡车怎么办?是否在所有加油站都建立尿素加注站?”王意宝说:“如果不能很好地普及,卡车用户加注尿素就很难实现。”而SCR技术本身存在低 Wang Yi Bao is Weichai Power Technology Center, an engineer in the post-processing technology research laboratory, mainly engaged in post-processing technology. In his view, the implementation of the national IV standard, in the two major issues of oil and urea supply, to ensure that the truck’s urea supply is more important. From the current national reserves and output, urea production capacity is not a problem, mainly the popularity of urea filling stations. “Currently the bus urea urea station construction is relatively easy, but after the actual implementation of Ⅳ, more widely distributed, more scattered operation of the truck how to do? Are all urea stations have been established urea station?” Wang Yibao said: “If not well popularized, it is very difficult for truck users to add urea.” "And SCR technology itself is low
