摘要
目前,机动车污染物排放已成为一个全球性问题,而在实验室达标的机动车或发动机,在实际使用过程中排放可能会大幅升高。面对这一情况,我国法规对发动机排放要求越来越高。文章通过对第五阶段和第六阶段PEMS试验方法对比,总结不同阶段车辆排放的要求。
At present,the emission of motor vehicle pollutants has become a global problem,and the emission of motor vehicles or engines that meet the standards in the laboratory may be greatly increased in the actual use.In the face of this situation,our country's regulations on engine emissions are increasingly high.By comparing the PEMS test methods in phase 5 and phase 6,this paper summarizes the requirements of different vehicle emission levels.
