摘要
进入7月,汽车行业正在经历一次大变动:全国许多省市宣布提前实施国家第六阶段机动车污染物排放标准(以下简称“国六”),比国家制定的原计划整整提早了一年。相比国五排放标准,轻型车国六排放标准增加了实际道路行驶排放控制要求和更严格的颗粒物数量排放标准,将大幅度加大后处理系统的难度,大量汽车也需使用颗粒捕捉器(Gasoline Particulate Filter,GPF)达到法规要求;且蒸发排放控制要求更加严格,需安装车载加油油气回收系统(Onboard Refueling Vapor Recovery,ORVR),对加油过程的油气排放进行控制;同时引入了严格的车载诊断系统(On-Board Diagnostics,OBD)控制要求。这些对汽车企业的开发要求很高。
Since July 2019,the vehicle industry has undergone one time of great changes.In China,many cities and provinces have announced in advance to implement the national stageⅥemission regulation,before the original national plan for exactly one year.As compared to the national stageⅤemission standard,for the light weight vehicles,in the national stageⅥ,more strict standard for emission of particles and emission control requirement under actual driving roads,are added,this will increase the difficulty of post-processing largely,and a good number of vehicles are in need to use gasoline particulate filter(GPF)so as to arrive at law requirement.Evaporation emission control is required with higher requirement,onboard refueling vapor recovery system is needed to control oil vapor discharge in refueling process.At the same time,strict control requirement for On-Board diagnostics(OBD)is introduced.All these will pose even higher needs for the development of vehicles enterprises.Senshata Technology Co.provides sensors which meet the requirement of national stageⅥemission standard,for clients in the Chinese market.
