摘　　要：空气质量问题是目前各大城市需要重点解决的环境问题之一,因为其对打造宜居城市环境有非常重要的意义。对现阶段的城市空气环境做分析研究可知汽车尾气的大量排放对空气质量造成了显著的影响,因此在实践中为了改善大气质量,控制排放等措施的采取非常关键。对汽车尾气排放问题做综合讨论可知,要有效的控制排放,需要对柴油机尾气排放当中的碳烟和氮氧化物进行控制,电控高压共轨燃油系统在具体利用中可以有效的改善燃油的喷雾特性以及燃烧进程,在柴油器尾气控制方面发挥着重要的作用,所以文章就相关的内容进行分析,旨在为实践提供帮助与指导。The problem of air quality is one of the environmental problems that need to be addressed in major cities,because it is of great signifi cance for creating a livable city environment.Analysis and research on the current urban air environment shows that the large amount of vehicle exhaust emissions have a signifi cant impact on air quality.Therefore,in practice,to improve air quality,it is critical to take measures to control emissions.A comprehensive discussion on the issue of automobile exhaust emissions shows that to eff ectively control emissions,it is necessary to control the soot and nitrogen oxides in diesel exhaust emissions.The electronically controlled high-pressure common rail fuel system can eff ectively improve fuel spray in specifi c applications.The characteristics and combustion process play an important role in diesel exhaust control,so the article analyzes the relevant content to provide help and guidance for practice.
