The invention relates to the technical field of automobile exhaust treatment, in particular to a testing device of an automobile exhaust purifier. The device comprises a frame body and two feeding mechanisms arranged on the frame body in a spaced mode; each feeding mechanism comprises an air supply assembly, each air supply assembly comprises an annular clamping frame set, and each annular clamping frame set comprises at least one annular clamping frame used for clamping a filter element. Identical arc-shaped holes are formed in the annular wall of each annular clamping frame in the axial direction; the air supply assembly further comprises sealing barrels, each sealing barrel is provided with a tail gas communicating hole, each sealing barrel comprises a sealing plate corresponding to thecorresponding arc-shaped hole, and the sealing plates can penetrate through all the annular clamping frames of one feeding mechanism. The device also includes a tail gas testing mechanism communicated with the air supply assemblies formed by the annular clamping frame sets and the sealing barrels. The problems that in the prior art, when comparison testing is conducted on two sets of filter elements, the filter elements need to be replaced frequently, and efficiency is low can be solved.
Description
technical field [0001] The invention relates to the technical field of automobile exhaust gas treatment, in particular to a testing device for an automobile exhaust gas purifier. Background technique [0002] Ceramic catalytic converters for automobile exhaust treatment are used to control the exhaust pollution of automobiles and reduce the emission of carbon monoxide, black smoke and other toxic gases. In the development, production and application stages of automobile exhaust purification catalysts, it is necessary to conduct performance tests on automobile exhaust purification catalysts in terms of automobile exhaust conversion efficiency and catalyst light-off performance, in order to screen out efficient automobile exhaust purification catalysts. In the process of testing the automobile exhaust purifier, it is often necessary to conduct a comparative test on the filter elements. [0003] However, most of the existing automobile exhaust purifier test devices can only te...
