Problems solved by technology

[0003] The traditional exhaust gas connection method is to directly connect the exhaust exhaust pipe to the exhaust outlet of the vehicle, and directly pump it. Using this method will cause exhaust gas leakage during the test process because the exhaust recovery pipe is not in close contact with the exhaust outlet of the vehicle. , which has a great influence on the fuel consumption and emission test data of the whole vehicle; and it is impossible to carry out exhaust exhaust work on the models with two exhaust outlets on the whole vehicle
During the test, the exhaust outlet was not in full contact with the exhaust outlet of the vehicle, causing the vehicle exhaust to be unable to be recovered by the exhaust recovery pipe normally, which easily made the test personnel uncomfortable due to the influence of the vehicle exhaust

Abstract

The invention discloses a dual-pipe automobile tail gas transfer tool, and belongs to the technical field of tail gas detection devices. The dual-pipe automobile tail gas transfer tool comprises a first pipeline and a fixed ring sleeve, wherein a first high temperature resistant rubber pipe is connected to one end of the first pipeline in a sleeving mode; the part, connected to the first pipelinein a sleeving mode, of the first high temperature resistant rubber pipe is fixed in a clamping mode through a throat clamp; the first pipeline is welded to an inverted-V-shaped welded pipe; a metal hose is welded to a second pipeline, and another metal hose is welded to a third pipeline; the second pipeline and the third pipeline are correspondingly connected and fixed to a second high temperatureresistant rubber pipe and a third high temperature resistant rubber pipe by using a connecting mode between the first pipeline and the first high temperature resistant rubber pipe; and the fixed ringsleeve is fixedly clamped to the surface of the inverted-V-shaped welded pipe through a bolt being matched with a threaded hole. According to the dual-pipe automobile tail gas transfer tool, the structure is simple, the pipelines are fixedly installed by the rubber pipes being matched with the throat clamps, the air impermeability is good, the influence on the collection accuracy of automobile tail gas caused by the leakage of the automobile tail gas cannot occur, and the accuracy of test results is improved.

Description

technical field [0001] The invention relates to the technical field of exhaust gas detection devices, in particular to a double-pipe automobile exhaust transfer tool. Background technique [0002] With the rapid development of the automobile industry and the enhancement of environmental awareness, the fuel consumption and emission requirements of the vehicle are getting higher and higher. During the fuel consumption and emission test of the whole vehicle, the exhaust gas pipe of the vehicle is connected with the exhaust gas recovery pipe of the emission analysis instrument. Then collect and analyze the collected vehicle exhaust storage samples to analyze the fuel consumption and emissions of the whole vehicle, and provide data on vehicle exhaust emissions. The tightness of the connection between the exhaust pipe of the automobile and the exhaust gas recovery pipe of the emission analysis instrument directly affects the data results of the fuel consumption and emission of th...
