Claims (1)

Каталитический нейтрализатор отработавших газов двигателей внутреннего сгорания, содержащий корпус, образующий перепускной канал с размещенными в нем реактором, имеющим по крайней мере два последовательно расположенных сотовых каталитических блока, образующих между собой полость, которая сообщается с перепускным каналом перепускными окнами, сообщенным с впускным органом, отличающийся тем, что перепускной канал сообщается с полостью между блоками проходными каналами, образованными, по крайней мере, двумя соосными цилиндрами, размещенными таким образом, что часть одного цилиндра перекрывает часть другого цилиндра, а в проходных каналах размещены сужающие устройства.A catalytic converter for exhaust gases of internal combustion engines, comprising a housing forming a bypass channel with a reactor disposed therein, having at least two successive honeycomb catalytic units forming a cavity therebetween that communicates with the bypass channel bypass windows in communication with the inlet body, characterized the fact that the bypass channel communicates with the cavity between the blocks of the passage channels formed by at least two coaxial cylinders nnym so that a portion of one cylinder overlaps part of the other cylinder, and has flow channels narrowing device.
