CASSETTE CATALYST CONVERTER Russian patent published in 2005 - IPC

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: invention can be for cleaning exhaust of compression ignition internal combustion engines. Proposed cassette catalyst converter has housing with external and internal walls with thermal insulation between said walls, solid particles filtering unit, porous penetrable cerement catalyst oxidizing, reducing and oxidizing-reducing units, cross partitions with through and blind ports, inlet and outlet branch pipes. Porous filtering unit for solid particles and porous penetrable cermet catalyst oxidizing, oxidizing-reducing and reducing and installed in series in pairs into through and blind ports of cross partitions to form cassettes. Each following partition is turned relative to longitudinal axis of converter, relative to preceding partition, through angle equal to 180°. Each unit is arranged in through and blind ports of partitions of its cassette.

EFFECT: improved efficiency of cleaning of exhaust gases, increased economy of engine, reduced consumption of fuel, increased service life and improved manufacturability.
