The invention relates to the technical field of automobile exhaust gas treatment, in particular to a testing device for an automobile exhaust gas purifier. The device includes: a frame body; also includes two feeding mechanisms, the two feeding mechanisms are arranged on the frame body at intervals, each feeding mechanism includes an air supply assembly, and the air supply assembly includes a set of ring clamping frame groups, Each group of ring holders includes at least one ring holder for clamping the filter element, and the same arc-shaped holes are arranged in the axial direction of the ring wall of each ring holder; the air supply assembly also includes a seal Barrels are provided with exhaust communication holes, and each sealed barrel includes a sealing plate corresponding to the arc-shaped hole, and the sealing plate can pass through all the annular clamping frames of a feeding mechanism; it also includes an exhaust gas testing mechanism, which is connected to the annular The air supply assembly formed by the clamping frame group and the sealed barrel is in communication. The invention can solve the problem of low efficiency due to the need to frequently replace the filter elements when comparing and testing two sets of filter elements in the prior art.
Description
technical field [0001] The invention relates to the technical field of automobile exhaust gas treatment, in particular to a test 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 test ...
