Abstract

The invention relates to the technical field of automobile tail gas treatment, in particular to a catalyst core of an automobile tail gas catalyst. The catalyst core of the automobile tail gas catalyst comprises a fixed plate, a mounting hole, a first catalytic core body, a second catalytic core body, and catalyst coatings, wherein the fixed plate is fixed into a shell, the mounting hole is formed in the fixed plate, the first catalytic core body and the second catalytic core body are arranged in a spaced mode along the axial direction of the mounting hole, and the catalyst coatings are arranged on the first catalytic core body and the second catalytic core body. According to the catalyst core of the automobile tail gas catalyst and a manufacturing technology of the catalyst core, the structural design is reasonable and novel, in the manufacturing technology, the catalytic core bodies are subjected to pretreatment so that the catalytic efficiency of the catalyst core can be remarkably improved, and therefore, the catalytic effect of the automobile tail gas catalyst is better and stronger.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust gas treatment, in particular to a catalyst core body of an automobile exhaust gas catalytic converter. Background technique [0002] Catalyst refers to a catalytic device that converts harmful gases such as CO, HC and NOx emitted from automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction. The exhaust gas treatment efficiency and effect of existing catalytic converters are poor. And it cannot reflect the working state of the catalytic converter in real time. [0003] In addition, the catalysis of the existing exhaust gas catalytic converter is not very ideal. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an automobile exhaust gas catalytic converter, which can improve the exhaust gas treatment efficiency and exhaust gas treatment effect of the catalytic converter, and can refle...
