摘要
部分主要城市在2019年开始执行国六排放标准法规,各大主机厂不断对国六燃油汽车的研发,并逐渐由台架试验往整车实际道路试验发展。文章选择满足国五的轻型车,参考法规要求,主要研究实际道路排放试验中CO、NOx和PN的排放结果。研究发现在RDE实验中,CO主要集中在城市与高速工况下生成,激烈驾驶持续时间越长NOx的排放量越大,而国五轻型车在PN控制方面,还面临更多挑战。
Some major cities will start to implement the China six emission legislation in 2019.Major automotive manufa-cturers research and develop the China six vehicles,and gradually develop from test bench to real drive emission test.In this paper,referring to the requirements of C6 regulations,the light vehicle that meet the requirements of C5 emission legislation is selected and the emission results of CO,NOx and PN are mainly studied in the real drive emission test.The research find that CO is mainly generated in urban and motorway conditions.The longer the intense driving lasted,the greater the NOx emission becomes,and the C5 light vehicle is faced with more challenges in PN control.
