A diesel engine includes an exhaust-gas purification device and allows the exhaust-gas purification device to be disposed at the upper face side of the diesel engine. The exhaust-gas purification device purifies exhaust gas discharged from the diesel engine. The direction of a long side of the exhaust-gas purification device is perpendicular to the direction in which a crankshaft, included in the diesel engine, extends. An exhaust throttle device is disposed between an exhaust manifold, included in the diesel engine, and an exhaust gas inlet, included in the exhaust-gas purification device.

An internal combustion engine, includes: an engine main body; a structural member disposed around the engine main body; a bracket including a support plate and a plurality of leg pieces depending from the support plate and connected to the structural member; a turbocharger including a turbine and a compressor, the turbine being connected to a side of the support plate opposite to the structural member; an exhaust pipe connected to a central part of the turbine and extending in a direction away from the compressor; and an engine auxiliary disposed between the structural member and the support plate, wherein the leg pieces are arranged unevenly to provide a higher heat shielding performance on a side of the exhaust pipe than on a side of the compressor with respect to the support plate.

A muffler for an exhaust system of an internal combustion engine includes a muffler housing having a peripheral wall elongated along a longitudinal housing axis. The muffler has an end wall on each axial end region of the peripheral wall and a muffler insert, surrounded by the peripheral wall and supported on the peripheral wall. A retaining wall extends substantially in the direction of the longitudinal housing axis and a first exhaust-gas routing pipe is positioned with a first end region engaging in an opening in the peripheral wall and is secured to the peripheral wall and retained with a second end region on the retaining wall. The first exhaust-gas routing pipe is retained in its second end region on the retaining wall by force closure or interlocking.

A vehicle, internal combustion engine, exhaust system, housing includes housing shell areas (10, 12), which are connected together in a folded connection area (32). The folded connection area includes a folded edge area (20, 22), extending along a folded edge longitudinal axis (L), and a plurality of spaced apart crimped sections (24, 26), which extend essentially at right angles to the folded edge longitudinal axis (L) and away from the folded edge area (20, 22) and provide intermediate spaces (28, 30). Some of the crimped sections (24, 26), of one housing shell area mesh with an intermediate space formed between two crimped sections (24, 26) of another housing shell area and overlap the folded edge area (20, 22) of the other housing shell area (10, 12) such that the folded edge area (20, 22) of the other housing shell area (10, 12) is held between the crimped sections (24, 26).

A muffler for an exhaust system of an internal combustion engine includes a muffler housing with a peripheral wall which extends longitudinally in the direction of a housing longitudinal axis. At least one base wall is surrounded by the peripheral wall or/and retained on the peripheral wall and delimits a chamber in the muffler housing. At least one base wall opening is surrounded by an opening edge region which is bent at an essentially plane base wall region of the base wall essentially in the direction of the housing longitudinal axis. The at least one base wall opening receives an exhaust pipe with a press fit in at least one base wall.

An exhaust system and a method of joining components of an exhaust system comprises obtaining an outer sleeve, a first pipe with a first end, and a second pipe with a second end. The method includes inserting the first end of the first pipe within the outer sleeve to define a first overlap, inserting the second end of the second pipe within the outer sleeve to define a second overlap, and radially inwardly deforming the outer sleeve and the first pipe at the first overlap. The outer sleeve and the second pipe are radially inwardly deformed at the second overlap. The outer sleeve and the first pipe as well as the outer sleeve and the second pipe are pressed into engagement with one another along the length of first overlap and the second overlap to define a pipe joint.

In one embodiment, there is disclosed an apparatus for decontaminating exhaust gasses. The apparatus includes a monolith catalytic substrate having a length and a width. The substrates length separates first and second opposed ends. The first end and second ends each have a one piece retention ring fitted thereon. The apparatus includes a housing having a length separating opposed, spaced apart open first and second ends. The housing has a side wall extending substantially unbroken there between to define a body having an interior space. The monolith catalytic substrate is disposed in said interior space. The housing has a greater length than said monolith catalytic substrate. The substrate is centered in the housing and the housing is swaged at the first and second ends respectively to engage the retention rings and retain the monolith catalytic substrate within the interior space in said housing.

An aftertreatment system comprises a SCR system. The SCR system includes a housing having an inlet, an outlet and defining an internal volume. At least one catalyst can be positioned within the internal volume. A mounting support is positioned around at least a portion of a perimeter of the housing. A heat shield is positioned around the perimeter of the housing such that the housing is positioned substantially within the heat shield. A portion of the heat shield is disposed on and in contact with the mounting support. A clamp is positioned around a heat shield perimeter. The clamp is positioned on the portion of the heat shield disposed on and in contact with the mounting support. The mounting support is configured to transmit a clamping force of the clamp on the heat shield to the housing to prevent buckling of the heat shield from the clamping force.

An apparatus, system and method for seaming an end cap to an end of a target object using a fixed, rigid roller carriage that is configured to move along a direction that is orthogonal to a rotation axis of the end cap and the target object. The end cap seaming apparatus and system preferably comprise servo motors that move the roller carriage and rotate the end cap and the target object. The end cap seaming apparatus and system may be configured to learn the shape of the end cap and the target object by learning a shape of an end cap holding member on which the end cap is held. An automated method of seaming the end cap to the target object is executed based on the learned shape of the end cap holding member.

The catalyst module is designed for use in an emission control system of a stationary incinerator. It comprises a stack frame, into which several mounting units are inserted strung together. The mounting units have a peripheral side wall as well as several partitions, which are entangled with one another and form a lattice with a plurality of mounting shafts, in which in each case one catalyst is inserted. The catalysts are pressed into position preferably with the interposition of an elastic fitting element.
