The disclosure relates to a gas-carrying exhaust gas housing of an internal combustion engine comprising: a manifold section, having a central axis and multiple manifold pipe connectors, for securing on a flange plate for connecting to a cylinder of an internal combustion engine; a catalyst housing section having a central axis; and an exhaust pipe connector section provided downstream of the catalyst housing section, for connecting to an onward-conveying exhaust system. In addition, together with catalyst housing section and exhaust pipe connector section, the manifold section forms a two-shell exhaust housing having a first half shell and a second half shell, wherein the two half shells have a separation plane (T) running parallel to the central axis at least in sections, wherein the manifold section has multiple integral manifold pipe connectors which can be attached directly to a flange plate.

A two-piece, stamped muffler having an integrally-attached aerodynamic shield having a flat bottom shape is disclosed. The muffler may be formed with a substantially flat lower surface. The aerodynamically-improved muffler set forth herein is provided as an aerodynamic shield that is incorporated into an extended flange provided in the shell blank, as a deflector that is attached to a muffler lower shell body and the clamshell flange such as by welding, that is separately attached to the clamshell flange only such as by welding, or that is separately attached to the lower shell only, again possibly by welding. For dual stamped mufflers, the shield may be used jointly with an incremental shield separate from, or integrated into, the spare tire well to connect the twin dual muffler shields to achieve vehicle aerodynamic requirements. A muffler having the aerodynamic shield deflects underbody air flow outside of the rear fascia cavity.

An aftertreatment system includes an inlet conduit assembly, an aftertreatment component cartridge, and an outlet conduit assembly. The inlet conduit assembly receives an exhaust gas and includes an inlet coupling flange portion. The aftertreatment component cartridge is coupled to the inlet conduit assembly and receives the exhaust gas from the inlet conduit assembly. The aftertreatment component cartridge also includes an adaptor. The outlet conduit assembly is coupled to the aftertreatment component cartridge and receives the exhaust gas from the aftertreatment component cartridge. The outlet conduit assembly includes an outlet coupling flange portion. The inlet coupling flange portion, adaptor, and outlet coupling flange portion cooperate to suspend the aftertreatment component cartridge within the aftertreatment system.

A manufacturing method of a sub-muffler outer cylinder is provided. The manufacturing method includes pushing one push roll toward two receive rolls, and then bending a plate-shape workpiece to form the sub-muffler outer cylinder made of a cylindrical-shaped body. A push-in amount in a part of the workpiece corresponding to a corner part of the cylindrical-shaped body is made larger than a push-in amount in a part of the workpiece corresponding to a side part of the cylindrical-shaped body to form the cylindrical-shaped body having a polygonal cross-sectional shape.

An exhaust pipe structure includes an exhaust pipe, a branching portion including an inflow port, a first flow path, a second flow path, a first discharge port, and a second discharge port, a first muffler, a first pipe, a second muffler, and a second pipe. The second flow path is lower in position in an up-down direction of a vehicle than the first flow path at a downstream side part of the second flow path including at least a portion of the second discharge port. The second pipe is lower in position in the up-down direction of the vehicle at an upstream side part connected to the second discharge port than an upstream side part of the first pipe connected to the first discharge port.

An exhaust gas heat recovery device includes an inner cylinder, a first fluid passage that is formed in the inner cylinder and in which first fluid flows, an outer cylinder that is formed by at least two divided bodies to surround the inner cylinder, and a second fluid passage that is formed between the inner cylinder and the cuter cylinder and in which second fluid flows.

A soundproof cover (30) is equipped with: multiple unit soundproof covers (31R, 31L) forming a portion of the circumferential cross section (30s); and connecting parts (35) provided on the periphery of the circumferential cross section (30s), and connecting the multiple unit soundproof covers (31R, 31L) in a detachable manner. The multiple unit soundproof covers (31R, 31L) are configured so as to be capable of being attached and detached with respect to a muffler (20) by moving the unit covers in a direction (the radial direction (R)) orthogonal to the axial direction (A) of the muffler (20).

A pipe (11), carrying exhaust gas, of an exhaust system (1) of an internal combustion engine (9), with a tubular body (15) carrying exhaust gas, and with at least one attachment part (12) separate with respect to the tubular body (15), which is added laterally to the tubular body (15) so that externally on the tubular body (15) a cavity (13) is arranged delimited at least partially by the attachment part (12), which extends in the circumferential direction (14) of the tubular body (15) over less than 360.

A tank for motor vehicle includes a tank wall, a fill opening, an outlet opening, a plurality of functional components, and a plurality of attachment formations.
