为使柴油机排放达到国Ⅳ标准,国际上通用的技术方案有两种,即SCR和EGR。而两种技术路线实施的基础,都依赖于高压燃油喷射系统。面对即将实施的国Ⅳ排放法规,燃油系统生产企业有哪些看法?又将如何应对?面临四大困难《商用汽车新闻》记者了解到,在燃油系统生产企业看来,国Ⅳ标准实施面临四方面的困难。硬件方面的困难有二。“降低油品含硫量、提升尿素添加便利性,这两点已是行业内老生常谈的问题,只是到目前为止还看不到能够得到多大程度上的解决。如果这两个问题得不到妥善解决,那能不能找到降低损失的方法?”某企业负责人表示。软件方面的困难同样有
In order to make the diesel engine discharge meet the national IV standard, there are two kinds of international common technical solutions, namely SCR and EGR. The two technical routes to implement the basis, all rely on high-pressure fuel injection system. In the face of the upcoming implementation of the State Ⅳ emission regulations, what are the views of the fuel system manufacturers? And how to deal with? Face four difficulties “Commercial Vehicle News” reporter learned that, in the fuel system manufacturing enterprises, the implementation of national IV standard faces four Difficulties in the area. There are two hardware difficulties. “Reduce the sulfur content of oil, improve the convenience of adding urea, these two points have been the commonplace problems in the industry, but so far still can not see how much can be solved .If these two problems can not be Properly resolved, then we can find ways to reduce the loss? ”An enterprise official said. The same is true with software
