CATALYTIC CONVERTER AND CATALYTIC UNIT Russian patent published in 2023 - IPC F01N3/28 

FIELD: catalytic converters.

SUBSTANCE: invention is related to systems for the exhaust gases of internal combustion engines (ICE), in particular to catalytic converters. The catalytic converter comprises a housing, an expanding inlet pipe with a flange, and catalytic blocks located inside the housing. The housing and the inlet pipe have rectangular sections, and the catalytic blocks are connected to each other and to the body in the form of a honeycomb reactor. The housing on both sides and the expanding inlet pipe on the side of docking with the housing have borders along the perimeter, forming flanges, for docking with each other with a detachable connection. Inside the expanding inlet pipe, a guide is installed in the form of two diffusers connected to each other and to the inlet pipe by vertical plates and horizontal plates forming a permanent connection. The vertical plates are spaced apart along the edges of the upper and lower planes of the diffusers, and the horizontal plates are located in the plane of the longitudinal axis of symmetry of the catalytic converter. The catalytic blocks are connected to each other and to the housing by a detachable connection.

EFFECT: implementing the invention provides an increase the service life and reduction of operating costs, reduction of energy resources by reducing the list of equipment used, reduction of manufacturing time, including the use of ready-made elements for assembling a catalytic converter.
