An automobile three-way catalytic converter assembly and its manufacturing and packaging process

Abstract

The invention discloses a three-way vehicle catalytic converter assembly and a manufacturing and packaging technology thereof, and belongs to the field of machine manufacturing. The three-way vehicle catalytic converter assembly comprises an assembly barrel, a catalytic converter generator, a muffler cavity, a water discharge structure, an air intake pipe, an air escape pipe and thermal shrouds, wherein the catalytic converter generator is arranged inside the assembly barrel; the muffler cavity is adjacent to the catalytic converter generator; the water discharge structure is arranged on the lateral wall of the assembly barrel where the muffler cavity is placed; the air intake pipe is arranged at one end of the assembly barrel; the air escape pipe is arranged at the other end of the assembly barrel; the thermal shrouds are arranged at two sides of the assembly barrel where the catalytic converter generator is arranged. By providing a pressure tank structure, the problem that a honeycomb carrier easily displaces is solved; the liquid inside the assembly barrel is automatically discharged under the gravity action by providing the water discharge structure; the liquid accumulated inside the three-way catalytic converter is avoided; the problems that sundries such as sludge are easily attached to the barrel of the three-way catalytic converter assembly to affect the catalytic effect and the service life are solved by providing the thermal shrouds; the service life of the three-way catalytic converter assembly is prolonged; the catalytic effect of the three-way catalytic converter assembly is improved.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to an automobile three-way catalytic converter assembly and its manufacturing and packaging process. Background technique [0002] Automobile exhaust emissions are the main source of air pollution in modern cities. To reduce pollution emissions, it is mainly to rely on the installation of three-way catalytic converters containing catalysts to allow CO, NO X Wait for the harmful gas to become a gas suitable for being discharged into the atmosphere. The selection of liner and the packaging of ceramic carrier are the key processes in the production of three-way catalytic converters, mainly relying on the liner with thermal expansion function to wrap the fragile ceramic carrier coated with precious metals, through molds and briquettes , press the wrapped ceramic carrier into the barrel to form a firm and reliable assembly. Under the current conventional technical conditions, du...

AI Technical Summary

Problems solved by technology

The effusion cannot be discharged from the cylinder, which will corrode the cylinder and shorten the life of the cylinder, thus affecting the service life of the entire three-way catalytic converter

The existing three-way catalytic converter, because it is located at the bottom of the vehicle and used for a long time, will inevitably stick to sludge and other debris, which will affect the heat dissipation of the three-way catalytic converter, so its catalytic effect will be greatly affected , its service life will be shortened; there is to eliminate the resonance problem of the connection
