机动车尾气中氮氧化物的分析检测技术

Analysis and Detection Technology of Nitrogen Oxides in Motor Vehicle Exhaust

机动车尾气当中的氮氧化物会对生态环境和人类带来影响,对其进行有效分析,可以确认有害气体的排出是否超标。基于此,本文主要介绍了几种常见的机动车尾气氮氧化物分析检测技术工作原理,并构建了一套机动车尾气氮氧化物评价体系,这几种方法均可以对机动车尾气氮氧化物浓度的变化情况进行及时反应,但各有优点,需要通过使用一些辅助设备才能更好地提升氮氧化物的分析效果。

The nitrogen oxides in motor vehicle exhaust can have an impact on the ecological environment and humans.Effective analysis of them can confirm whether the emission of harmful gases exceeds the standard.Based on this,this article mainly introduces the working principles of several common motor vehicle exhaust nitrogen oxide analysis and detection technologies,and constructs a set of motor vehicle exhaust nitrogen oxide evaluation system.These methods can timely respond to changes in the concentration of motor vehicle exhaust nitrogen oxides,but each has its advantages.It is necessary to use some auxiliary equipment to better improve the analysis effect of nitrogen oxides.
