After-sales Treatment Measures for Gasoline Engine Exhaust
Wang Zhixin acting Chang'an Zhang Boqian
Abstract:The main components of gasoline engine exhaust gas are CO, HC, NOx, etc. The treatment of automobile exhaust gas is a systematic project. In the field of automobile service, the treatment of exhaust gas generally forms regular treatment plans and measures. The exhaust gas diagnostic instrument can detect cars in real time. At the same time, it also guides front-line maintenance personnel to treat exhaust gas in a targeted manner, and realizes a series of truthful recording and tracking of maintenance process and maintenance quality in the after-sales field, which plays a role in improving the quality of service and the technical quality of internal employees. Good equipment guarantees that the emission of automobile pollutants is controlled from the field of automobile after-sales.
Key words:exhaust gas,HC,CO,NOX,CO2,treatment
1 引言
據交管局最新数据统计,2019年上半年全国汽车保有量达2.5亿辆。纵观近十年,中国汽车的保有量从2009年的7600万辆,到现在的2.5亿辆,增长量超200%。综合测算国内汽车保有量能达到千人450辆,也就是每个人0.45辆汽车,再乘以14.5亿,就是6.3亿辆。按照这个水平,中国汽车保有量有望在2020年会超过美国,成为全球第一。
2 人工智能II代尾气诊断引导系统
随着汽车保有量的增加,在中国大、中型城市,汽车尾气排放已成为主要的大气污染源,对于汽油发动机排放的污染物主要有哪些呢?人工智能II代尾气诊断引导系统可以实时检测汽车尾气的排放的各项数据,并引导4S店维修人员检测、维修,最后形成尾气超标车辆诊断调试报告单。
3 国家针对汽车尾气的排放标准
GB18285-2018及GB3847-2018对汽车尾气排放设置了双怠速排放限制规范、简易瞬态工况法排放限值、加载减速法排放烟度限值以及自由加速法排放烟度限值等。……
