| 摘要 |
The invention relates to a device for treating exhaust gases of internal combustion engines, including a housing, at least one gas treating body, a first support material, an internal shield, and a second support material. The housing includes an inlet, an outlet and an interior chamber between the inlet and the outlet. The gas treating body or bodies are located within the chamber, and the first support material is located between the outer surface of the gas treating body or bodies and the inner surface of the chamber. The internal shield is coupled with the inner surface of the housing via the second support material, which is located between the outer surface of the internal shield and the inner surface of the housing. The cross sectional area of the housing is generally constant in the region proximal to the internal shield. |
