Abstract: A manifold system for an internal combustion engine, having a housing, which is designed as a collecting manifold and which has two inlet openings and an outlet opening for the flow connection of two outlets of an internal combustion engine to an exhaust system and at most two connection openings provided on the housing for connecting a double-shell inner air-gap-insulated manifold. An exhaust system is developed in such a way that, at the same time, the tone of the exhaust gas noise and thus of the exhaust system is optimized over a plurality of important rotational speed ranges of the internal combustion engine by a modular assembly. For this purpose, at least one separate inner air-gap-insulated manifold having a connection opening, an inlet opening, and an outlet opening is provided, which is connected to the housing by the outlet opening, and at least one separate outer air-gap-insulated manifold having an inlet opening and an outlet opening is connected to the connection opening of the inner air-gap-insulated manifold. All air-gap-insulated manifolds are completely formed of sheet metal, and each air-gap-insulated manifold has a separate one- or multi-part inner shell and a one- or multi-part separate outer shell. All inner air-gap-insulated manifolds are structurally or geometrically identical and all outer air-gap-insulated manifolds are structurally or geometrically identical, wherein the inner air-gap-insulated manifolds are not structurally identical and not geometrically identical to the outer air-gap-insulated manifolds.

Abstract: An exhaust pipe flange with an exhaust gas pipe and with a flange plate fastened to the exhaust gas pipe, wherein the flange plate has an inner side which can be turned toward a cylinder head with a sealing surface which can be placed directly or indirectly against a cylinder head, and a seat in which the exhaust gas pipe is received. The exhaust gas pipe is joined to the flange plate and sealed in the region of the seat on the inner side by a welded connection.

Abstract: A multipart gas pipe flange for connecting to a counter-flange of an internal combustion engine, having at least one flange plate designed as an outer flange, and having a flange inner part that can be received in said flange plate and is used for attaching a gas pipe which is connected downstream of the inner part in the flow direction and which is fluidically connected. The flange plate has at least one recess for the flange inner part, said recess having at least one inner surface and an inner diameter Di, and a mounting surface which can be placed at least indirectly on the counter-flange. The flange inner part has an outer surface which corresponds to the inner surface and which has an outer diameter Da. The outer surface and the inner surface have a basic shape which tapers in the flow direction, and when being clamped against the counter flange, the outer surface and the inner surface can be clamped relative to each other at least partially in a direction (R) which runs radially in relation to a central axis of the outer surface and/or the inner surface.

Abstract: A flange plate for a manifold of an exhaust-gas system for internal combustion engines, which flange plate can be fixed via at least one holding device to an exhaust-gas outlet connecting piece of the internal combustion engine by a first outer layer, formed as a mounting layer, which can be placed at least partially directly or indirectly against the exhaust-gas outlet connecting piece via a seal, and the flange plate can be applied to the holding device by a second outer layer, formed as a holding layer, in order to generate a holding force F, acting at a right angle to the mounting layer, for sealingly placing the mounting layer against the exhaust-gas outlet connecting piece, and the flange plate having at least a first intermediate layer which is arranged, relative to the holding force F, between the mounting layer and the holding layer. Here, the first intermediate layer is formed as a cavity structure, wherein the cavity structure has single- or multiple-part wall parts which extend in a direction parallel to the mounting layer and are arranged adjacent to one another, the wall parts having a width b1, measured in a direction parallel to the mounting layer, and having a height h1, measured in a direction at a right angle to the mounting layer, where h1>b1, wherein the different wall parts delimit a plurality of cavities which are open towards the mounting layer or towards the holding layer or, together with the mounting layer and the holding layer, delimit an open-ended channel.

Abstract: A housing for fluidically connecting an exhaust gas line to an exhaust gas heat exchanger, wherein the main flow channel of the housing extends in the direction of a central axis (X), from an inlet opening to an outlet opening, with an average flow cross section (SQ). In the main flow channel, at least one opening is provided in the housing for a valve shaft, and on the housing, at least one bypass opening formed by a connecting piece is provided between the inlet opening and the outlet opening. The housing is formed by a maximum of two deep-drawn sub-shells made of sheet metal, wherein the connecting piece is formed circumferentially around the bypass axis (Y) for connecting an exhaust gas heat exchanger via the upper shell and/or via the lower shell.
