双排气管车辆排气取样检测研究

Related Research on Dual Trachea Vehicle Exhaust Sampling Detection

双排气管汽油车进行尾气检测时,环保监管部门的监管要求与环保尾气检测机构的实际操作常存在分歧。对于双排气管汽油车究竟插入几个取样探头测试,才能准确、科学地检测出尾气中的含量浓度,从而对尾气检测结果做出公正准确的判断,从检测标准要求、比对实验方法验证、排气管构造图解析3个方面对该问题进行了讨论。

While discussing the actual number of probes used in inspecting dual exhaust pipes car, there existed many different points between requirements from the environment sector and actual operation of environmental inspection carried out by inspection agent. We need to find out how many probes should be used during actual inspection so as to get an accurate concentration data exactly in a scientific way. We therefore could give out a fair judgment based on the inspection result of exhaust gas. Here by in this article, we demonstrated in the following three aspects： inspection specification; verification based on comprehension; detailed analysis of the construction image of exhaust pipe.
