摘要
介绍了满足国IV/国V排放标准柴油机的几种关键技术,同时对各种技术的特点或限制因素作了分析,最后探讨了国IV/国V柴油机发展的两种主流技术路线,并指出只有多种技术的组合使用才能使柴油机满足越来越严格的排放法规要求。
Some effective measures for diesel engines to meet National IV/V Emission Standards are summarized,and the advantages or disadvantages of these technologies are analyzed.Then Two main technical routes for National IV/V Emission Standards,Optimized combustion＋SCR and EGR＋DPF/DOC are discussed and compared in detail.Finally,the combination of several key technologies to realize stricter emission limitations of diesel engines are highlighted.
