国Ⅳ车辆燃用国Ⅲ柴油的影响研究

Influence of national Ⅳ trucks with national Ⅲ diesel

本文通过对国Ⅳ车辆使用国Ⅲ柴油时的整车性能及排放进行试验数据分析及研究,得出国Ⅳ车辆在短期内限定工况下可以使用国Ⅲ柴油,但排放不能完全达到国家第Ⅳ阶段车用压燃式发动机与汽车污染物排放标准,且影响车辆性能不宜长期使用的结论,为国Ⅳ产品的设计、售后服务提供依据和参考。

Through the analysis of experimental data,this article come to a conclusion that the national Ⅳ trucks can use national Ⅲ diesel in short period of time at limited conditions,but the exhaust emission cannot meet all the requirements of the national Ⅳ emission standard,and the long-term use national Ⅲ diesel will degrade vehicles ＇performance.The results of the study can provide the basis and the reference for the design of heavy truck,vehicle maintenance.
