浅析汽车尾气超标成因及M站尾气治理方案

Analysis on the Causes of Excessive Automobile Exhaust and the Treatment Scheme of Exhaust Gas in M Station

分析汽车尾气中有害物质CO、HC和NOx的形成机理以及有害物质给环境与人类带来的危害,阐述三元催化器等净化装置的工作原理;从多个方面分析汽车尾气超标的原因和引起尾气超标的常见故障,通过尾气超标的分析,并结合尾气超标引发的故障,提出相应的M站尾气治理方案。

The formation mechanism of harmful substances CO, HC and NOx in automobile exhaust and the harm of harmful substances to the environment and human beings are analyzed. The working principle of three-way catalytic converter and other purification devices is described. The causes and common faults causing excessive exhaust were analyzed from multiple aspects. Based on the analysis of excessive exhaust gas, combined with the faults caused by excessive exhaust gas, the corresponding exhaust treatment scheme of M station is proposed.
