Abstract:
A mounting mat (4) for an exhaust gas treatment device (10), the mounting mat (4) comprises two opposing main surfaces (5, 6) and at least one edge surface (7) extending between the main surfaces; at least one portion of the at least one edge surface comprises a protection coating comprising inorganic particles (15), and the inorganic particles have an average diameter of at least 1 µm.
Abstract:
Mounting mat (4) for holding a substrate (2) of a pollution control element or chemical reactor (10), the pollution control element or chemical reactor (10) comprising more than one substrate (2), wherein the substrate (2) comprises a front face (2f), a rear face (2r) and at least three flat side faces (4) extending between the front (2f) and the rear face (2r), and wherein the mounting mat (4) is shaped such that it covers at least partially an edge (5) enclosed by two flat side faces (4).
Abstract:
Erfindungsgemäß wird eine Abgasnachbehandlungsvorrichtung für ein Abgassystem einer Brennkraftmaschine vorgeschlagen, mit zumindest einem austauschbaren AGN-Modul (1), das dazu vorgesehen ist, in einem Abgasstrom angeordnet zu werden, das zumindest eine Dichtfläche (2) zur gasdichten Verbindung mit einem benachbarten Bauteil (3) aufweist, die dazu vorgesehen ist, entlang einer zumindest im Wesentlichen senkrecht zu der Dichtfläche (2) wirkenden Dichtrichtung (5) mit dem benachbarten Bauteil verpresst zu werden, und mit einer Montagefuhrung (4), die dazu vorgesehen ist, für das AGN-Modul (1) eine von der Dichtrichtung (5) abweichende Vormontagerichtung (6) vorzugeben.
Abstract:
The present invention relates to an arrangement for fitting an exhaust cleaning unit (2) in an exhaust passage (1b). The arrangement comprises an annular resilient component (7) which is fitted round the exhaust cleaning unit (2) at a distance from the gasket (5). The annular resilient component (7) has a first contact portion (7a) adapted to coming into contact with a wall surface (3) of the exhaust cleaning unit (2) and a second contact portion (7b) adapted to coming into contact with a wall surface (1b) of the exhaust passage when the exhaust cleaning unit (2) is in a fitted state in the exhaust passage, and that the annular resilient component (7) has the characteristic of keeping the exhaust cleaning unit (2) in a centred position in the exhaust passage with a spring force.
Abstract:
An exhaust treatment device includes an inner shell, an outer shell and insulation material positioned between the inner shell and the outer shell. An inlet tube has an end in communication with a cavity defined by the inner shell. A substrate for treating engine exhaust is positioned within the inner shell. A baffle plate includes a plurality of apertures positioned such that the exhaust passes through the apertures prior to entering the substrate. The baffle plate supports an end of the inner shell and the inlet tube.
