Abstract

An exhaust flow apparatus including an exhaust carrier having first and second opposing end portions, the first and second end portions each including and terminating at an end, the end of the first end portion defining an exhaust inlet, and the second end portion defining a plurality of exhaust carrier outlets, wherein at least the second end portion of the exhaust carrier is configured to be housed within an exhaust pipe of an exhaust stack. The exhaust flow apparatus further includes an exhaust deflector oriented on or in proximal relation to the end of the second end portion of the exhaust carrier such that the exhaust deflector directs exhaust toward one or more of the plurality of exhaust carrier outlets during use of the apparatus.

Claims

exact text as granted — not AI-modified
1 . An exhaust flow apparatus, comprising:
 an exhaust carrier having first and second opposing end portions, the first and second end portions each including and terminating at an end, the end of the first end portion defining an exhaust inlet, and the second end portion defining a plurality of exhaust carrier outlets, wherein at least the second end portion of the exhaust carrier is configured to be housed within an exhaust pipe of an exhaust stack; and   an exhaust deflector oriented on or in proximal relation to the end of the second end portion of the exhaust carrier such that the exhaust deflector directs exhaust toward one or more of the plurality of exhaust carrier outlets during use of the apparatus.   
     
     
         2 . The exhaust flow apparatus of  claim 1 , wherein the exhaust deflector is a cap integral with or mounted onto the end of the second end portion of the exhaust carrier. 
     
     
         3 . The exhaust flow apparatus of  claim 1 , wherein each of the outlets in the plurality of exhaust carrier outlets is a slot defining a longitudinal axis and the plurality of exhaust carrier outlets includes first and second sets of slots oriented such that the longitudinal axes of substantially all the slots in the first set of slots are not coaxial with any of the longitudinal axes of the slots in the second set of slots. 
     
     
         4 . The exhaust flow apparatus of  claim 1 , further comprising a particulate carrier having first and second end portions each including and terminating at an end, wherein at least the second end portion of the particulate carrier is configured to be housed within the exhaust carrier. 
     
     
         5 . The exhaust flow apparatus of  claim 4 , wherein the exhaust carrier includes a flow restriction portion configured to cause a Venturi effect between the first and second end portions of the exhaust carrier during use of the apparatus, and wherein at least the end of the second end portion of the particulate carrier is configured to be housed within the flow restriction portion of the exhaust carrier. 
     
     
         6 . An exhaust flow apparatus, comprising:
 an exhaust carrier having first and second opposing end portions, the first and second end portions each including and terminating at an end, the end of the first end portion defining an exhaust inlet, and the second end portion defining a plurality of exhaust carrier outlets, wherein at least the second end portion of the exhaust carrier is configured to be housed within an exhaust pipe of an exhaust stack;   a cap integral with or mounted onto the end of the second end portion of the exhaust carrier such that the cap directs exhaust toward one or more of the plurality of exhaust carrier outlets during use of the apparatus;   a particulate carrier having first and second end portions each including and terminating at an end, wherein at least the second end portion of the particulate carrier is configured to be housed within the exhaust carrier.   
     
     
         7 . The exhaust flow apparatus of  claim 6 , wherein each of the outlets in the plurality of exhaust carrier outlets is a slot defining a longitudinal axis and the plurality of exhaust carrier outlets includes first and second sets of slots oriented such that the longitudinal axes of substantially all the slots in the first set of slots are not coaxial with any of the longitudinal axes of the slots in the second set of slots. 
     
     
         8 . The exhaust flow apparatus of  claim 6 , wherein the exhaust carrier includes a flow restriction portion configured to cause a Venturi effect between the first and second end portions of the exhaust carrier during use of the apparatus, and wherein at least the end of the second end portion of the particulate carrier is configured to be housed within the flow restriction portion of the exhaust carrier. 
     
     
         9 . An engine exhaust system, comprising:
 an exhaust carrier having first and second opposing end portions, the first and second end portions each including and terminating at an end, the end of the first end portion defining an exhaust inlet, and the second end portion defining a plurality of exhaust carrier outlets;   an exhaust deflector oriented on or in proximal relation to the end of the second end portion of the exhaust carrier, the exhaust deflector being configured to direct exhaust toward one or more of the plurality of exhaust carrier outlets; and   an exhaust stack comprising an exhaust pipe defining an exhaust pipe outlet, wherein the exhaust pipe is oriented such that the exhaust pipe outlet is downstream from the exhaust carrier outlets and is configured to house at least the second end portion of the exhaust carrier.   
     
     
         10 . The engine exhaust system of  claim 9 , wherein the exhaust deflector is a cap integral with or mounted onto the end of the second end portion of the exhaust carrier. 
     
     
         11 . The engine exhaust system of  claim 9 , wherein each of the outlets in the plurality of exhaust carrier outlets is a slot defining a longitudinal axis and the plurality of exhaust carrier outlets includes first and second sets of slots oriented such that the longitudinal axes of substantially all the slots in the first set of slots are not coaxial with any of the longitudinal axes of the slots in the second set of slots. 
     
     
         12 . The engine exhaust system of  claim 9 , further comprising a particulate carrier having first and second end portions each including and terminating at an end, wherein at least the second end portion of the particulate carrier is configured to be housed within the exhaust carrier. 
     
     
         13 . The engine exhaust system of  claim 12 , wherein the exhaust carrier includes a flow restriction portion configured to cause a Venturi effect between the first and second end portions of the exhaust carrier during use of the system, and wherein at least the end of the second end portion of the particulate carrier is configured to be housed within the flow restriction portion of the exhaust carrier. 
     
     
         14 . The engine exhaust system of  claim 12 , wherein the exhaust deflector is a cap integral with or mounted onto the end of the second end portion of the exhaust carrier. 
     
     
         15 . The engine exhaust system of  claim 12 , wherein each of the outlets in the plurality of exhaust carrier outlets is a slot defining a longitudinal axis and the plurality of exhaust carrier outlets includes first and second sets of slots oriented such that the longitudinal axes of substantially all the slots in the first set of slots are not coaxial with any of the longitudinal axes of the slots in the second set of slots.
