| 摘要 |
The invention concerns a catalyzer housing (21) and a corresponding catalyzer support (26), in particular for a catalyzer located near the engine of a motor vehicle. The housing (21), which can preferably be a casting, has a larger cross-section than the catalyzer support and has an approximately rectangular opening through which the catalyzer support (26) can be inserted. The catalyzer suport (26) is fastened to a flat or convex holder plate (24) which closes the opening in the housing (21) like a lid. The catalyzer support (26) projects into the interior (28) of the housing (21). The arrangement permits cost-effective and independent manufacture of housing (21) and catalyzer support (26) and facilitates insertion and interchange of catalyzers. In particular, a catalyzer can be rotated at mid service life through 180 DEG and hence more profitably exploited. |
