Abstract
An exhaust aftertreatment device has a unitary cast inlet that is configurable to have a 90° or 180° entry of combustion gasses relative to flow through tubular elements housing a diesel oxidization catalyst and a diesel particulate filter. The cast component provides the primary structural support for a tubular element connected to the casting element.
Claims15
An exhaust aftertreatment device comprising:
- a structural component receiving an internal combustion engine combustion gasses through an inlet integral with the said structural component, having a mounting surface formed about a given axis on a closed face of said structural component, said structural component having internal flow passages directing flow of said combustion gasses from said inlet toward a direction substantially parallel with said given axis and exiting said structural component at a circumferential surface;
- a tubular shell structurally connected to said circumferential surface;
- and, at least one exhaust aftertreatment device positioned in and carried by said tubular shell, wherein the exhaust aftertreatment device is substantially supported by said structural component, wherein said structural component is a casting, and wherein said casting has multiple mounting bosses for providing a structural interconnection between the exhaust aftertreatment device and the frame of a vehicle with which the exhaust aftertreatment device is utilized.
A vehicle comprising:
- a frame;
- an exhaust aftertreatment device comprising a structural component receiving an internal combustion engine combustion gasses through an inlet integral with the said structural component, having a mounting surface formed about a given axis on a closed face of said structural component, said structural component having internal flow passages directing flow of said combustion gasses from said inlet toward a direction substantially parallel with said given axis and exiting said structural component at a circumferential surface;
- a tubular shell structurally connected to said circumferential surface;
- and, at least one exhaust aftertreatment device positioned in and carried by said tubular shell;
- and,
- said structural component being adapted to be mounted to said frame whereby the exhaust aftertreatment device is substantially supported by said structural component, wherein said structural component is a casting, and wherein said casting has multiple mounting bosses for providing a structural interconnection between the exhaust aftertreatment device and said frame of the vehicle with which the exhaust aftertreatment device is utilized.
