An assembly for coupling thermally a thermoelectric generator (TEG) to an exhaust manifold includes a first heat-exchanger, a first dielectric-layer, a TEG, and a direct-bond-copper-arrangement (DBC). The first dielectric-layer overlies a portion of the outer surface of the first heat-exchanger. The first dielectric-layer is formed by firing a thick-film dielectric material onto the stainless steel of the first heat-exchanger. The TEG defines a first contact suitable to be coupled thermally and electrically to the first conductor-layer. The DBC is interposed between the first dielectric-layer and the first contact of the TEG. The DBC is formed by an adhesion-layer formed of high-adhesion-copper-thick-film in contact with the first dielectric-layer, a bond-layer formed of copper-thick-film that overlies and is in contact with the adhesion-layer opposite the first-dielectric-layer, and a copper-foil-layer that overlies and is in contact with the bond-layer opposite the adhesion-layer.

An aftertreatment system includes a dosing module. The aftertreatment system includes a selective catalytic reduction unit disposed fluidly downstream of the dosing module. The aftertreatment system includes a conduit fluidly connecting the dosing module to the selective catalytic reduction unit. The conduit has a coating disposed on a surface thereof. The coating is exposed to exhaust passing through the conduit and to the selective catalytic reduction unit. The coating is configured to capture and deactivate platinum passing through the conduit.

An assembly for treating gaseous emissions includes a substrate body having cells for the passages of emissions gas. Lengths of metal wire are located in selected ones of the cells and an induction heating coil is mounted adjacent the substrate body for generating a varying electromagnetic field for inductive heating of the assembly including gaseous emissions passing along the cells. Within the cells, parts of the cell walls and parts of the wire surfaces are exposed to the passage of the gaseous emissions and both the cell wall parts and the wire surface parts have pollution treating catalyst at their surfaces.

Described is a method of coating the inside of an exhaust gas purification catalyst filter with a predetermined amount of catalyst slurry while adjusting the distribution of catalyst components in or on a cell wall of the filter. A predetermined amount of catalyst slurry can be injected into an internal channel of a filter to solve conventional problems caused by excess or surplus slurry injection. The predetermined amount of slurry injected into the internal channel of the filter is coated on or in the cell wall, depending on the viscosity and particle size of the slurry. This enables a coating profile in which the slurry distribution at a front portion of the filter and the slurry distribution at a back portion of the filter differ from each other. In addition, the coating profile on the inner surface of the cell wall or in the pores of the cell wall can be adjusted through the subsequent air blowing, so that the back pressure of the filter and the performance of the catalyst filter, such as catalytic activity, can be improved. In addition, the coating length in the filter can be adjusted by controlling the pressure of air during the air blowing.

An assembly for treating gaseous emissions includes a substrate body having cells for the passages of emissions gas. Lengths of metal wire are located in selected ones of the cells and an induction heating coil is mounted adjacent the substrate body for generating a varying electromagnetic field. In this way the metal wires are heated, resulting in heating of the substrate body and heating of exhaust gas flowing in the cells. The metal wires are distributed non-uniformly through the substrate body to obtain a desired heating pattern.

Inductance heating metal is located in the substrate body and an induction heating coil is mounted adjacent the substrate body for generating a varying electromagnetic field for inductively heating the metal and thereby heating the substrate body. A greater concentration of the metal is located near the front of the substrate body than near the rear.

A circumferential coating material contains colloidal silica, silicon carbide, and titanium oxide different in particle diameters from silicon carbide, coats a circumferential surface of a honeycomb structure monolithically formed by extrusion, including as a main component, cordierite having a porosity of 50 to 75%, and forms a circumferential coating layer. A circumferentially coated honeycomb structure has a honeycomb structure comprising latticed porous partition walls defining and forming a plurality of polygonal cells forming through channels and extending from one end face to the other end face, and a circumferential coating layer formed by coating at least a part of a circumferential surface of the honeycomb structure with the circumferential coating material.

The surface coating layer is provided on the outer circumferential surface of the metal pipe. The surface coating layer contains an inorganic glass base material and has concave portions and convex portions on an outer surface of the surface coating layer. The concave portions and the convex portions are constructed using electrocoating with an electrocoating resin. The concave portions have a virtually circular shape when seen in a direction perpendicular to the outer circumferential surface of the metal pipe and are lower than a first reference surface. The first reference surface has an average height of the outer surface of the surface coating layer. The convex portions are located on peripheral edge portions of the concave portions and surround the concave portions.
