Engine system with air diverter

Abstract

A disclosed engine system includes an engine having upper and lower portions, an ancillary component positioned above the upper portion of the engine and having upper and lower portions, and an air diverter adjacent to both the upper portion of the engine and the lower portion of the ancillary component.

1 . A engine system, comprising:
 an engine having upper and lower portions;   an ancillary component positioned above the upper portion of the engine and having upper and lower portions; and   an air diverter adjacent to both the upper portion of the engine and the lower portion of the ancillary component.   
     
     
         2 . The engine system of  claim 1 , wherein the air diverter is oriented in substantially non-parallel relation to a longitudinal axis defined by the engine. 
     
     
         3 . The engine system of  claim 2 , further comprising an engine compartment and an exhaust stack in fluid communication with the engine compartment, the exhaust stack including an exhaust pipe and an exhaust tube residing at least partially within the exhaust pipe, the exhaust stack being configured to cause air to flow in a direction substantially parallel to the longitudinal axis defined by the engine during operation of the engine. 
     
     
         4 . The engine system of  claim 1 , wherein the ancillary component is an exhaust aftertreatment component connected to the engine. 
     
     
         5 . The engine system of  claim 4 , further comprising an engine compartment and an exhaust stack in fluid communication with the engine compartment, the exhaust stack including an exhaust pipe and an exhaust tube connected to the exhaust aftertreatment component and residing at least partially within the exhaust pipe. 
     
     
         6 . The engine system of  claim 1 , wherein the air diverter is a first air diverter and the engine system further comprises a second air diverter. 
     
     
         7 . The engine system of  claim 1 , wherein the air diverter comprises a baffle attached to a baffle housing. 
     
     
         8 . The engine system of  claim 7 , wherein the baffle and the baffle housing cooperate to define a port. 
     
     
         9 . The engine system of  claim 8 , wherein the baffle housing includes a top panel and first and second opposing side panels. 
     
     
         10 . The engine system of  claim 9 , wherein the top panel of the baffle housing is attached to a cradle configured to carry the ancillary component. 
     
     
         11 . The engine system of  claim 10 , wherein the ancillary component is an exhaust aftertreatment component connected to the engine. 
     
     
         12 . The engine system of  claim 11 , wherein the exhaust aftertreatment component is a canister. 
     
     
         13 . An engine system, comprising:
 an engine housing defining an engine compartment; and   an engine substantially residing in the engine compartment, having upper and lower portions, and defining a longitudinal axis;   an exhaust stack in fluid communication with the engine compartment, the exhaust stack including an exhaust pipe and an exhaust tube residing at least partially within the exhaust pipe;   an ancillary component positioned above the upper portion of the engine and having upper and lower portions; and   an air diverter adjacent to both the upper portion of the engine and the lower portion of the ancillary component and oriented in substantially non-parallel relation to the longitudinal axis defined by the engine, the air diverter comprising a baffle attached to a baffle housing.   
     
     
         14 . The engine system of  claim 13 , wherein the air diverter is a first air diverter and the engine system further comprises a second air diverter. 
     
     
         15 . The engine system of  claim 13 , wherein the baffle and the baffle housing cooperate to define a port. 
     
     
         16 . The engine system of  claim 13 , wherein the baffle housing includes a top panel and first and second opposing side panels. 
     
     
         17 . The engine system of  claim 16 , wherein the top panel of the baffle housing is attached to a cradle configured to carry the ancillary component. 
     
     
         18 . The engine system of  claim 17 , wherein the ancillary component is an exhaust aftertreatment component connected to the engine. 
     
     
         19 . The engine system of  claim 18 , wherein the exhaust aftertreatment component is a canister. 
     
     
         20 . An engine system, comprising:
 an engine housing defining an engine compartment; and   an engine substantially residing in the engine compartment, having upper and lower portions, and defining a longitudinal axis;   an exhaust stack in fluid communication with the engine compartment, the exhaust stack including an exhaust pipe and an exhaust tube residing at least partially within the exhaust pipe;   an exhaust aftertreatment component connected to the engine, positioned above the upper portion of the engine, and having upper and lower portions; and   a cradle configured to carry the exhaust aftertreatment component;   first and second air diverters, each air diverter being adjacent to both the upper portion of the engine and the lower portion of the exhaust aftertreatment component and oriented in substantially non-parallel relation to the longitudinal axis defined by the engine, and each air diverter comprising a baffle attached to a baffle housing comprising a top panel and first and second opposing side panels, the top panel of the baffle housing of each air diverter being attached to the cradle.
