Description

Technical Field

[0001] The utility model relates to the technical field of motor vehicle exhaust gas testing, and particularly relates to an auxiliary device for testing motor vehicle exhaust gas emissions. Background Technique

[0002] Automobile exhaust gas is the waste gas generated when an automobile is in use, containing hundreds of different compounds. The pollutants therein include solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead, sulfur oxides, etc. While directly endangering human health, automobile exhaust gas will also have a profound impact on the environment in which humans live. The sulfur dioxide in the exhaust gas has a strong pungent smell, which is likely to cause acid rain, resulting in acidification of soil and water sources and affecting the growth of crops and forests.

[0003] However, when the existing exhaust gas detection device for automobile testing detects automobile exhaust gas, it is easy for the exhaust gas to leak, resulting in the exhaust gas being emitted into the air, thereby affecting the environment and personnel. Moreover, when the existing exhaust gas detection device for automobile testing is in use, it is difficult to be installed on the tailpipes of different automobiles, and the adaptability is poor.

[0004] For example, in an exhaust gas detection device for automobile testing disclosed in Chinese Patent CN212031400U, by connecting a wide mouth and a detector, an intake pipe is fixedly sleeved at one end of the connecting wide mouth. When this exhaust gas detection device for automobile testing is in use, by sleeving the connecting wide mouth onto the automobile tailpipe and inserting the intake pipe and the airbag into the automobile tailpipe, the two clamping rings are driven to move relative to each other by rotating the bolt, so as to firmly fix the connecting wide mouth on the automobile tailpipe, and by starting the air pump to input compressed air into the airbag, the gap between the intake pipe and the automobile tailpipe is filled by the inflated airbag, thereby realizing the seal between the automobile tailpipe and the intake pipe. During detection, automobile exhaust gas leakage can be avoided. This device avoids the leakage of automobile exhaust gas during detection, and at the same time can adapt to the detection of different automobile tailpipes, with strong adaptability and convenient use.
