Abstract
A metal engaging plate is arranged at an inlet side of a core. A tooth portion of the engaging plate engages with end edges of catalyst carriers. Mutual separation of the stacked catalyst carriers can be suppressed by the tooth portion of the engaging plate. Accordingly, an aperture opening phenomenon that the catalyst carriers are separated from one another by a flowing-in pressure of the exhaust gas can be prevented from being generated. As a result, purification performance of the exhaust gas can be improved.
Claims23
A catalyst converter comprising:
- a tubular member having a wall;
- a carrier contained in the tubular member, the carrier including a series of sheets, sheets being superposed with each other, a respective sheet extending transversely between a respective point and respective another point on the wall;
- and
- an engaging plate crossing the respective sheet, the engaging plate being engaged with the series of sheets.

A catalyst converter comprising:
- first and second honeycomb cores, the first and second honeycomb cores being made of first and second corrugated catalyst carriers respectively, the first and second catalyst carriers having first and second series of sheets, first and second sheets extending in substantially parallel to overlap with each other so that first cells are partitioned between the first sheets and second cells are partitioned between the second sheets;
- a tubular member for containing the first and second honeycomb cores therein, the tubular member having an inlet and an outlet;
- and
- a metal partitioning member for partitioning an interior of the tubular member into first and second container spaces, both the first and second container spaces being connected to the inlet and the outlet respectively, the first and second honeycomb cores being arranged in the first and second container spaces respectively such that the first and second sheets extend in a direction intersecting with the partitioning member, and a gas flowing in from the inlet and then flowing into the cells from an inlet side end faces of the first and second cores and then flowing out from the outlet.
