摘要 |
A catalyst arrangement comprises a combustion chamber (16) for burning a gas mixture for the exhaust gas arrangement of an IC engine, a housing (100) for the combustion chamber and built into the exhaust gas arrangement of the engine in a predetermined flow direction, a catalyst (10) arranged in the housing, an ignition device (18) for igniting the gas mixture, and a flame stabilizing device (50) arranged in the housing upstream of the ignition device. The flame stabilizing device has a flow-permeable structure having a number of openings with a maximum cross-section structured so that flame spread is prevented upstream of the ignition device. An Independent claim is also included for an exhaust gas arrangement containing the catalyst arrangement. Preferred Features: The housing widens on both sides from the cross-section of the exhaust gas arrangement to a maximum cross-section of the catalyst. The flame stabilizing device comprises a wire grid, a wire mesh, a non-coated catalyst or a sintered body. |
