Abstract

Кожух (102) для устройства (100) последующей обработки для обработки выхлопных газов из двигателя внутреннего сгорания содержит ступенчатый канал (126), выполненный с возможностью расположения над верхней поверхностью устройства (100) последующей обработки и продолжающийся, по существу, по всей длине устройства (100) последующей обработки, причем ступенчатый канал (126) выполнен с возможностью направления потока очищающего воздуха продольно вдоль наружной и верхней поверхности устройства (100) последующей обработки, при этом внутренняя поверхность ступенчатого канала (126) образует по меньшей мере первую продолжающуюся вниз ступень (134, 136, 138) и вторую продолжающуюся вниз ступень (134, 136, 138), которые разнесены по длине устройства (100) последующей обработки, для направления по меньшей мере части потока очищающего воздуха вниз.The casing (102) for the after-treatment device (100) for treating exhaust gases from an internal combustion engine contains a stepped channel (126) configured to be located above the upper surface of the after-treatment device (100) and extending essentially along the entire length of the device ( 100) post-treatment, wherein the stepped channel (126) is configured to direct the flow of cleaning air longitudinally along the outer and upper surface of the post-treatment device (100), wherein the inner surface of the stepped channel (126) forms at least a first downwardly extending stage (134 , 136, 138) and a second downwardly extending stage (134, 136, 138) which are spaced apart along the length of the post-treatment device (100) to direct at least a portion of the cleaning air flow downward.
