A heating apparatus for a fluid flow system having a container body includes a heater element and a strip. The heater element is within the container body and includes an electrical resistance element, a sheath, and an insulating material. The sheath extends along a predefined path through the container body and surrounds the electrical resistance element along the predefined path. The insulating material is disposed about the electrical resistance element between the electrical resistance element and the sheath. The insulating material electrically insulates the electrical resistance element from the sheath. The strip is disposed inside the container body and defines a tortuous geometry that follows the predefined path. The strip defines a plurality of openings at discrete locations along the strip. The heater element extends through the plurality of openings and is configured to contact the strip at the discrete locations.

A process manufactures an exhaust gas treatment device including a tubular circumferential wall (14) elongated along a longitudinal axis (L) with two axial end areas, an exhaust gas treatment unit (52) arranged in the circumferential wall and a closing element (20, 38) connected to the circumferential wall at the two axial end areas. The exhaust gas treatment unit is held at the circumferential wall by a supporting material layer (54) enclosing the exhaust gas treatment unit and supporting same in relation to the circumferential wall. The process includes arranging a first of the two closing elements at one of the axial end areas of the circumferential wall, pushing the exhaust gas treatment unit enclosed by the supporting material layer into the circumferential wall from the other axial end area (18), and arranging a second of the closing elements at the other axial end area of the circumferential wall.

An assembly for treating gaseous emissions has a ceramic substrate body through which extend passages. The assembly has metal wires in selected ones of the passages, a first section of each wire electrically connected at one end thereof to an end of a second wire section and a distal end of the second section electrically connected to one end of a third wire section. The first and third wire sections are composed of a material having a lower electrical resistance than that of the second wire section. Part of each second wire section is located in a respective one of the selected passages.

An insulating device for a thermal and/or acoustic insulation of an exhaust system of a vehicle has a first half shell including at least a first connection rim and a second half shell including at least a second connection rim, the first half shell and the second half shell being connected by a welded joint at the connection rims. The connection rims are reshaped into a multiple fold. Further disclosed are a vehicle exhaust system having an exhaust gas-carrying duct and an insulating device circumferentially surrounding the duct, as well as a method for producing an insulating device for a thermal and/or acoustic insulation of an exhaust system of a vehicle.

In an exhaust gas processing device, an air-fuel ratio sensor is provided such that a measuring portion is located in a region surrounded by a downstream-side end surface of a TWC, an upstream-side end surface of a GPF, and an inner wall surface of a case against which the exhaust gas G that has passed through the TWC flows, that is the region a region on the GPF side of the center of the TWC.

A silencing apparatus is provided with a shell, ventilation pipes communicating with the inside of the shell, insertion holes which are respectively formed in the shell so as to have sizes smaller than surrounding skirt parts and allow the ventilation pipes to be loosely inserted in, and partitions partitioning the inside of the shell. In the silencing apparatus, at least, a sound-absorbing chamber partitioned by the partition and positioned adjacent to the insertion hole is filled with a sound-absorbing fiber material, and a sound-absorbing fiber material filling gap between the insertion hole and the ventilation pipe is closed by an annular closing member. To provide a silencing apparatus allowing a sound-absorbing chamber to be filled with sound-absorbing fiber material without a gap, even in a complicated configuration having the inside of a shell partitioned by a partition.

An exhaust component for a motor vehicle with improved corrosion resistance, including an internal volume, an inlet for receiving exhaust gas, and an outlet for expelling exhaust gas. The exhaust component includes at least one wall that is made of a diffusion surface alloyed metal sheet. The diffusion surface alloyed metal sheet comprises a secondary metal that is formed to a primary metal substrate by diffusion. A weld bead is applied to at least one of the edges of the diffusion surface alloyed metal sheet for edge protection or to join the edge of the diffusion surface alloyed metal sheet to another diffusion surface alloyed metal sheet. The weld bead includes a high chromium content filler metal to protect the weld bead and the primary metal substrate at the weld joint from corrosion.

A panel assembly includes a panel member, a frame member, and at least one first bar member, and at least one second bar member. The at least one first bar member and the at least one second bar member divide the panel member into a plurality of first areas defining a first height and a first width. The panel assembly also includes a plurality of support arrangements for dividing each first area into a plurality of second areas. Each support arrangement includes a first support member defining a first length such that the first width defined by the first area is greater than the first length. Each support arrangement also includes a second support member defining a second length such that the first height defined by the first area is greater than the second length.
