中重型商用车柴油机技术升级的驱动力,一个是排放标准的升级,另一个是用户对于燃油经济性的要求。一个产品核心的竞争力是如何做好排放和油耗的平衡,即获得低油耗的同时,排放要满足法规的要求。对于国Ⅴ和欧Ⅵ来说,主要还是两条路线,即SCR和EGR,实际上从国4发动机到国Ⅴ发动机,现在主流思路是采用SCR的技术路线。而在EGR方面我们也做了很多研究,现将研究数据和大家分享。
The driving force behind the technical upgrading of medium- and heavy-duty commercial vehicle diesel engines is an upgrade of emission standards and the other is the user’s demand for fuel economy. The competitiveness of a product core is how to make a good balance between emissions and fuel consumption, that is, to achieve low fuel consumption at the same time, emissions to meet regulatory requirements. For the country Ⅴ and Europe Ⅵ, the main line or two, namely, SCR and EGR, in fact, from the national 4 engine to the national V engine, the main idea now is to adopt the SCR technology route. In the EGR we have also done a lot of research, research data now and share with you.
