Abstract
A catalyzer arrangement for the exhaust gases of an internal combustion engine in which the catalyzer body (6, 7) is formed from a weave, knit or fabric of metal fibers, metal chips, metal wires, metal powder or a mixture of them which is pressed together in several layers (11) to form a pack in the outlet region (4) of the cylinder of the internal combustion engine in front of the exhaust gas manifold (5) and/or in the inlet region of the exhaust gas manifold (5). In addition, or as an alternative, the cylinder crown (8) in the cylinder (2) of the internal combustion engine can also be provided with a catalyzer body (9).
Claims22
Catalyzer arrangement for the exhaust gases of an internal combustion engine, in which the catalyzer body is formed from a structure selected from the group consisting of weave, knit and fabric of a material selected from the group consisting of metal fibers, metal wires and a mixture of said materials being pressed together in at least one layer, said layer having a grid structure and forming a pack in the outlet region of the cylinder of the internal combustion engine in front of the exhaust gas manifold, said layer being offset an adjacent layer, and said layer being doped with items selected from the group consisting of chips, small wire pieces and fillers, said items being connected to said material.
Catalyzer arrangement for the exhaust gases of an internal combustion engine, in which the catalyzer body is formed in a structure selected from the group consisting of a weave, knit and fabric and formed of a material selected from the group consisting of metal fibers, metal wires and a mixture of said materials, said materials being pressed together in at least one layer, said layer being doped with said materials so they connect to said structure and form a pack in the outlet region of the cylinder of the internal combustion engine before the exhaust gas manifold.
Catalyzer arrangement for the exhaust gases of an internal combustion engine, in which the catalyzer body is formed from a structure selected from the group consisting of weave, knit and fabric of a material selected from the group consisting of metal fibers, metal wires and a mixture of said materials being pressed together in at least one layer, said layer having a grid structure and forming a pack in an inlet region of the exhaust gas manifold, said layer being offset an adjacent layer, and said layer being doped with items selected from the group consisting of chips, small wire pieces and fillers, said items being connected to said material.
