[0002] As a clean energy source, hydrogen has the characteristics of high combustion efficiency, no pollution, and no decarbonization emissions, but it is also colorless, odorless, flammable and explosive. A small amount of gas emissions will still be generated during use, including hydrogen and methane gas. In order to protect the environment, countries have formulated corresponding atmospheric emission standards. The impact of exhaust gas generated after the use of hydrogen energy on the atmosphere needs to be evaluated through specific usage methods and actual exhaust gas component detection, such as the authorized patent CN202020104155.0, a fuel cell engine test system, which is tested through a series of processes. Since the research and use of hydrogen energy vehicles has just started in China, the exhaust gas detection devices of many hydrogen energy engines are relatively bulky and inconvenient and inflexible to use. Therefore, it is necessary to provide a more flexible solution for the detection of exhaust gas components of hydrogen energy vehicle engines. Utility Model Content

[0023] The heads of the exhaust gas inlet pipe 32 and the exhaust gas outlet pipe 33 are both provided with quick-connect hose clamps 34, the middle of the exhaust gas outlet pipe 33 is a telescopic pipe, a switch valve 36 is provided between the connecting pipe 35 and the collecting box 4, and a liquid level meter is provided in the collecting box 4.

[0025] The exhaust gas discharge pipeline of the tested hydrogen engine is connected to the exhaust gas intake pipe 32. After the exhaust gas enters, the moisture carried in the gas will condense to the bottom of the condensation tank 31, and the condensed water will be discharged to the collection box 4 through the connecting pipe 35 and the switch valve 36 at the bottom. The switch valve 36 can disconnect the connection between the collection box 4 and the condensation tank 31.

The exhaust gas enters the monitoring instrument 2 through the monitoring air inlet 21 to monitor whether the hydrogen and methane content in the exhaust gas meets the emission standards. Then it is discharged into the condensing tank 31 through the monitoring air outlet 22. The exhaust gas outlet pipe 33 at the top of the condensing tank 31 has a retractable hose, which is used to connect the exhaust pipes of different heights in actual use to the exhaust gas treatment equipment, and then discharge. The retractable hose is provided with a quick-connect hose clamp 34 to facilitate the rapid and effective connection of the exhaust pipe.
