| 摘要 |
The invention concerns a device for the catalytic conversion of exhaust gases in an exhaust system, in particular for the exhaust system of an internal combustion engine and preferably for spark ignition engines. The proposed device comprises at least two honeycomb elements (2, 3) mounted in an outer casing pipe (1) and through which the exhaust gas (G) flows in succession; one honeycomb element (3) is connected to the next by means of struts (12) which protrude into the honeycomb elements (2, 3). The honeycomb element (2) is arranged so as to leave a gap between itself and the outer casing pipe (1) and is provided with at least two shells (4, 5) which are connected to the mantel surface of the honeycomb element (2), and each of the shells is attached to an electrical current connection (6, 7). The device is also provided with electrically insulating connecting elements (15), one end of each connecting element (15) being connected to the shell (5 or 4, as appropriate), the other end being connected to the adjacent honeycomb element (3). The outer casing pipe has at least one beading (16) around its circumference, the beading resting in contact with the casing pipe (14) of the adjacent honeycomb element (3). |
