SECTIONAL CATALYTIC CONVERTER Russian patent published in 2006 - IPC F01N3/28 

FIELD: mechanical engineering; compression ignition internal combustion engines.

SUBSTANCE: proposed sectional catalytic converter has housing with catalytic filtering elements, cross partitions with slots and inlet and outlet branch pipes. Catalytic and filtering elements installed in slots of cross partitions are made in form of assembly sections of radial plates made of porous permeable cermet materials with filtering oxidizing and or filtering reducing properties. Cross partitions are made in from of sector-shaped plates alternating with slots so that slot of other end face of this section is arranged opposite to sector-shaped plate of other end face of assembly section. Each radial plate is fitted in slots of sector-shaped plates.

EFFECT: improved efficiency of cleaning of exhaust gases by developing areas of filtering and catalytic elements, reduced fuel consumption by decreasing counterpressure at engine exhaust and provision and provision of high quality of exhaust gas cleaning.
