Exhaust system thermal enclosure

Abstract

An exhaust system for a power system contained in an engine compartment. The exhaust system includes a mount for two or more exhaust treatment devices and an enclosure surrounding the two or more exhaust treatment devices. The enclosure defines a space with a higher temperature than a space defined by the engine compartment during steady state operation of the power system. At least one electronic or fluid device is coupled to the enclosure or mount and located on an exterior of the enclosure.

1 . A portion of an exhaust system for a power system contained in a engine compartment, comprising:
 a mount for two or more exhaust treatment devices;   an enclosure surrounding the two or more exhaust treatment devices and defining a space with a higher temperature than a space defined by the engine compartment during steady state operation of the power system; and   at least one of an electronic and fluid device coupled to the enclosure or mount and located on an exterior of the enclosure.   
   
   
       2 . The exhaust system of  claim 1 , further including a plate coupled to the enclosure or mount and supporting the at least one electronic or fluid device. 
   
   
       3 . The exhaust system of  claim 1 , wherein the at least one electronic or fluid device connects to one of the two or more exhaust treatment devices. 
   
   
       4 . The exhaust system of  claim 1 , wherein one of the two or more exhaust treatment devices includes a diesel particulate filter and one of the two or more exhaust treatment devices includes a regeneration device. 
   
   
       5 . The exhaust system of  claim 4 , wherein a head portion of the regeneration device is not surrounded by the enclosure. 
   
   
       6 . The exhaust system of  claim 5 , wherein the at least one electronic or fluid device connects to the head portion of the regeneration device. 
   
   
       7 . The exhaust system of  claim 5 , wherein the at least one fluid device includes fuel or combustion air used by the regeneration device. 
   
   
       8 . An enclosure surrounding two or more exhaust treatment devices but not surrounding the engine, the enclosure comprising:
 at least one removable panel to provide access to at least one of the two or more exhaust treatment devices.   
   
   
       9 . The enclosure of  claim 8 , wherein the enclosure includes at least a front, a back, a top, a bottom, a first side, and a second side to form a box structure. 
   
   
       10 . The enclosure  claim 8 , wherein at least one removable panel is a port configured to provide access to a sensor used in connection with one of the two or more aftertreatment devices. 
   
   
       11 . The enclosure  claim 8 , wherein one of the two or more exhaust treatment devices includes a diesel particulate filter and one of the two or more exhaust treatment devices includes a regeneration device. 
   
   
       12 . The enclosure  claim 11 , wherein at least one removable panel is configured to provide access to the regeneration device. 
   
   
       13 . The enclosure of  claim 11  wherein at least one removable panel is configured to provide access to the diesel particulate filter. 
   
   
       14 . An enclosure surrounding two or more exhaust treatment devices supported on a mount, the enclosure comprising:
 at least one mount opening configured to expose a footing of the mount.   
   
   
       15 . The enclosure of  claim 14  wherein the mount openings are located on a bottom of the enclosure. 
   
   
       16 . The enclosure of  claim 14  wherein the footings are mounted to a machine. 
   
   
       17 . The enclosure of  claim 14  wherein the footings are mounted to an engine. 
   
   
       18 . The enclosure of  claim 14  further including:
 an exhaust conduit configured to receive exhaust from an engine.   
   
   
       19 . The enclosure of  claim 14  further including:
 an exit conduit configured to deliver exhaust to the atmosphere.   
   
   
       20 . The enclosure of  claim 14  not surrounding an engine.
