1. A gas conduit, in particular for an internal combustion engine. 2.1 The invention proposes a gas conduit section (1), in particular an exhaust manifold, for an internal combustion engine, and also an internal combustion engine with an exhaust-gas catalytic converter arranged in the exhaust system. 2.2 According to the invention, the conduit section (1) has a porous inlay (2), preferably in the form of a sintered shaped body, which at least partially bears against its inner wall and forms a hollow body through which gas can flow freely; the internal combustion engine according to the invention has in its exhaust system, upstream of the exhaust-gas catalytic converter arranged therein, a conduit section which in particular includes a porous sintered shaped body through which gas can flow freely. 2.3 Use in particular in motor vehicles with an internal combustion engine.
1-11. (canceled)
A gas conduit section of an exhaust manifold for an internal combustion engine, comprising an inner wall and a porous inlay which at least partially bears against the inner wall and forms a hollow body through which gas can flow freely.
An internal combustion engine having an exhaust system in which an exhaust-gas catalytic converter is arranged, the exhaust system comprising a conduit section upstream of the exhaust-gas catalytic converter having an inner wall, and a porous, sintered, shaped body which at least partially bears against the inner wall of the conduit section and through which gas can flow freely, the sintered, shaped body being formed from sintered material particles which are predominantly metallic in form.
