The present invention discloses a motor vehicle exhaust
monitoring system, which belongs to the field of monitoring technology, and includes a sampling head
assembly, a collection monitoring
assembly and a micro
air pump. The collection monitoring
assembly includes a first six-way, an adsorption assembly, an absorption
bottle, an integrated
detector, a box-type sampling assembly and a second six-way. A one-way valve is provided between the adsorption assembly, the absorption
bottle, the integrated
detector and the box-type sampling assembly and the first six-way. A flow controller is provided between the adsorption assembly, the absorption
bottle, the integrated
detector and the box-type sampling assembly and the second six-way. The first pipeline is connected to the first six-way, the second pipeline is connected to the second six-way, the first pipeline is provided with a
dilution assembly, and a heat preservation area is provided outside the pipeline between the sampling head assembly and the one-way valve, and a
refrigeration area is provided outside the adsorption assembly and the absorption bottle. The present invention can realize rapid monitoring of
exhaust gas, improve the monitoring range of
exhaust gas components, and realize detailed analysis of each component of
exhaust gas.
