Automobile three-way catalyst

Abstract

The invention relates to the technical field of automobile catalysts, and discloses an automobile three-way catalyst. An upper shell is included. A lower shell is arranged at the bottom of the upper shell. A fixing sleeve is arranged at one end of the upper shell and one end of the lower shell. First bolts are arranged on the top of one side of the fixing sleeve. A bottom plate is arranged at thebottom of an inner cavity of the lower shell, a catalysis frame is arranged on the top of the bottom plate, a protection plate is arranged on one side of the top of the bottom plate, a sliding grooveis formed in one side of the front face of the lower shell, a limiting block is arranged on one side of the bottom of the lower shell, a filter plate is arranged on one side of the limiting block, a sliding rod is arranged on one side of the top of the filter plate, and a clamping block is arranged on one side of the bottom of the lower shell. According to the automobile three-way catalyst, through mutual cooperation of the limiting block, the filter plate and the clamping block, water in the lower shell can be better discharged conveniently, the lower shell is cleaned when blockage happens, accordingly, complexity during oil dirt blockage removing is avoided, and the cleaning convenience is improved.

Description

technical field [0001] The invention relates to the technical field of automobile catalytic converters, in particular to a three-way catalytic converter for automobiles. Background technique [0002] The automobile three-way catalytic converter is the most important external purification device installed in the automobile exhaust system. It can convert harmful gases such as CO, HC and NOx emitted from automobile exhaust into harmless carbon dioxide, water and Nitrogen, today's three-way catalytic converters are mostly welded in the process of connecting with other components, which makes it take more time to disassemble and replace the three-way catalytic converters during maintenance. At the same time, the interior of the three-way catalytic converter When clogging occurs, it takes a lot of time to clean up to remove the clog inside the three-way catalytic converter, and it is difficult to clean the clog. Contents of the invention [0003] (1) Solved technical problems ...
