| titleOfInvention | A vehicle exhaust gas test system |
| abstract | The utility model provides a vehicle exhaust gas testing system, comprising: a sample gas input pipeline, which is sequentially provided with a heating sampling pipe, a particle filter, a swirling condenser pipe and a first electromagnetic three-way valve along the airflow direction; a drying pipeline connected to the first electromagnetic three-way valve, the drying pipeline is sequentially provided with a steam-water separator, a liquid barrier, a constant temperature heater, a membrane dryer and a second electromagnetic three-way valve along the airflow direction; and The detection pipeline connected to the second electromagnetic three-way valve is provided with a flow sensor, an infrared gas sensor, an ultraviolet gas sensor and an oxygen sensor in sequence along the airflow direction. The beneficial effects of the utility model are as follows: the influence of environmental factors and the factors of the gas itself is eliminated, the components of the gas are tested under the same internal environment under different environments, the consistency of the test results of the optical devices is effectively guaranteed, and the machine is improved. The detection accuracy of motor vehicle exhaust gas reduces the dependence on the test environment. |
