Abstract
The catalytic converter has an axis and a housing having an inlet and an outlet. The housing contains hollow cylindrical catalyst means having an inner surface, an outer surface and passages for the exhaust gas which run from the inner surface to the outer surface. In a cross-section at right angles to the axis, the catalyst means surround an inner space of the catalyst means, with which space the inlet communicates and which space contains a limiting and/or guide member. This has a limiting and/or guide surface which approaches the inner surface of the catalyst means in a direction away from the inlet and distributes the exhaust gas, flowing into the inner space of the catalyst means during operation, uniformly over the passages of the catalyst means.
