Exhaust assembly for a prime mover of a transport power system

Abstract

Exhaust assemblies for emitting an exhaust from a prime mover while in transit are disclosed. The exhaust assembly can include a tail pipe that includes a raiser portion, a soot portion and an undercut outlet. The raiser portion is inclined at a first angle relative to a vertical axis of the exhaust assembly. The raiser portion is configured to receive the exhaust. The soot portion is connected to the raiser portion and is configured to receive the exhaust from the raiser portion. The soot portion is inclined at a second angle relative to the vertical axis. The undercut outlet is disposed at a tail end of the soot portion. The undercut outlet has an upper lip shielding fluid or debris from entering the exhaust assembly via the undercut outlet.

What is claimed is: 
     
         1 . An exhaust assembly for emitting an exhaust from a prime mover while in transit, the exhaust assembly comprising:
 a tail pipe that includes a raiser portion, a soot portion, and an undercut outlet;   wherein the raiser portion is inclined at a first angle relative to a vertical axis of the exhaust assembly, the raiser portion being configured to receive the exhaust,   wherein the soot portion is connected to the raiser portion and configured to receive the exhaust from the raiser portion, the soot portion is inclined at a second angle relative to the vertical axis, and   wherein the undercut outlet is disposed at a tail end of the soot portion, the undercut outlet having an upper lip shielding fluid or debris from entering the exhaust assembly via the undercut outlet.   
     
     
         2 . The exhaust assembly of  claim 1 , wherein the second angle is greater than the first angle. 
     
     
         3 . The exhaust assembly of  claim 1 , wherein an inclining direction of the soot portion and an inclining direction of the raiser portion are disposed along a same plane. 
     
     
         4 . The exhaust assembly of  claim 1 , further comprising a muffler outlet pipe elbow that is configured to receive the exhaust in a direction of the vertical axis and direct the exhaust to exit the muffler outlet pipe elbow at an inclining direction of the raiser portion. 
     
     
         5 . The exhaust assembly of  claim 1 , wherein the tail pipe includes a raiser portion elbow disposed between the raiser portion and the soot portion, wherein the raiser portion elbow is curved to receive the exhaust travelling in an inclining direction of the raiser portion and configured to direct the exhaust to exit the raiser portion elbow at an inclining direction of the soot portion. 
     
     
         6 . The exhaust assembly of  claim 1 , wherein the undercut outlet further comprises a lower lip disposed below the upper lip, the lower lip recessing into the soot portion such that the upper lip shields the lower lip from falling fluid or debris. 
     
     
         7 . The exhaust assembly of  claim 1 , wherein the tail pipe does not include a fluid drain. 
     
     
         8 . A transport power system for providing power while in transit, the transport power system comprising:
 a diesel engine having an engine exhaust outlet configured to release an exhaust; and   an exhaust assembly connected to the engine exhaust outlet, the exhaust assembly comprising a tail pipe, the tail pipe including:
 a raiser portion inclining at a first angle relative to a vertical axis of the exhaust assembly, the raiser portion being configured to receive the exhaust; 
 a soot portion connected to the raiser portion and configured to receive the exhaust from the raiser portion, the soot portion inclining at a second angle relative to the vertical axis; and 
 an undercut outlet disposed at a tail end of the soot portion, the undercut outlet having an upper lip shielding fluid or debris from entering the exhaust assembly via the undercut outlet. 
   
     
     
         9 . The transport power system of  claim 8 , wherein the second angle is greater than the first angle. 
     
     
         10 . The transport power system of  claim 8 , wherein an inclining direction of the soot portion and an inclining direction of the raiser portion are disposed along a same plane. 
     
     
         11 . The transport power system of  claim 8 , further comprising a muffler outlet pipe elbow receiving the exhaust in a direction of the vertical axis and curving the exhaust to exit the muffler outlet pipe elbow in an inclining direction of the raiser portion. 
     
     
         12 . The transport power system of  claim 8 , wherein the tail pipe includes a raiser portion elbow disposed between the raiser portion and the soot portion, wherein the raiser portion elbow is curved to receive the exhaust travelling in an inclining direction of the raiser portion and configured to direct the exhaust to exit the raiser portion elbow at an inclining direction of the soot portion. 
     
     
         13 . The transport power system of  claim 8 , wherein the undercut outlet further comprises a lower lip disposed below the upper lip, the lower lip recessing into the soot portion such that the upper lip shields the lower lip from falling fluid or debris. 
     
     
         14 . The power of  claim 8 , wherein the tail pipe does not include a fluid drain. 
     
     
         15 . The transport power system of  claim 8 , wherein the prime mover is configured to provide generate power for a transport climate control system. 
     
     
         16 . The transport power system of  claim 8 , wherein the prime mover is configured to generate power for an auxiliary power unit.
