Description

Technical Field

[0001] The utility model relates to the technical field of testing devices, in particular to an engine tail gas emission testing device. Background Art

[0002] In order to reduce environmental pollution, relevant departments need to test the exhaust gas emitted by automobile engines within a certain period of time to ensure that the exhaust gas generated by the automobile engine will not cause significant pollution to the atmospheric environment. Existing technology uses automobile exhaust analyzers to test engine exhaust emissions.

[0003] When the automobile exhaust analyzer is in use, the detection head and the handle are combined, and then the detection head is inserted into the tube body used for engine exhaust emissions. The bent part of the handle can be snapped onto the outer wall of the tube body, so that the detection head can be relatively stably connected to the tube body. Then the main body of the automobile exhaust analyzer is opened, allowing the detection head to detect the engine exhaust emissions. However, during this process, the detection head is easily separated from the engine exhaust emission tube body under the pulling force of the handle, thereby affecting the accuracy of the detection result.

[0004] The main reason for the above problems is that the automobile engine exhaust emission pipe is at a certain height relative to the ground, and only one end of the handle is connected to the engine exhaust emission pipe, and the other end of the handle is connected to the connecting cable. In addition, most parts of the handle are suspended in the air. When the engine starts, it will generate a large vibration force. At this time, under the action of the vibration force and the gravity of the suspended part of the handle, it is easy to cause the handle and the engine exhaust emission pipe to separate, thereby affecting the stable connection between the detection head and the pipe body. To address the above problems, we propose an engine exhaust emission test device. Utility Model Content
