Abstract

The invention discloses a three-way catalyst assembly, and relates to the technical field of manufacturing of three-way catalysts. The three-way catalyst assembly comprises a barrel body in which a catalyst assembly is arranged, wherein one end of the barrel body is connected with an air outlet flange through an air outlet end cover; the other end of the barrel body is connected with an air inlet pipe through an air inlet end cover; an air inlet flange is arranged at the front end of the air inlet pipe; the air inlet pipe is formed by assembling and welding an air inlet pipe half shell I and an air inlet pipe half shell II; a plurality of mounting brackets are arranged at a position, located at the joint of the two half shells, on the air inlet pipe; a heat insulation cover is arranged outside the air inlet end cover and the barrel body; a plurality of grooves are formed in the outer surface, positioned on the barrel body section, of the heat insulation cover. Compared with the prior art, the three-way catalyst assembly disclosed by the invention has the advantage that the problem that the air inlet end cone of the three-way catalyst of a conventional turbocharged engine is easy to break can be solved.

Description

technical field [0001] The invention relates to the technical field of manufacturing a three-way catalytic converter, in particular to a three-way catalytic converter assembly for a turbocharged engine. Background technique [0002] The three-way catalytic converter for automobiles is the most important external purification device installed in the exhaust system of automobiles. It can convert harmful gases such as CO, HC, and NOX emitted from automobile exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction. . In order to ensure that the parts around the catalytic converter are not affected by heat damage, it is usually necessary to install a heat shield on the catalytic converter for heat insulation treatment. However, most of the existing automotive catalytic converter heat shields are rectangular screen panels, which have poor heat resistance and deformation resistance. , Once the heat exceeds its tolerance range, it is very easy to be...
