Abstract
A hood assembly for a machine includes an enclosure within which at least one exhaust aftertreatment device is mounted. The engine hood assembly may be preassembled so that the exhaust aftertreatment system is integrated into the enclosure. This may allow the hood assembly to be assembled to the machine and the exhaust aftertreatment system mated to an exhaust pipe from the engine as a unit while the machine is being built on an assembly line. The engine hood assembly may include ventilation openings to assist in heat rejection from the engine compartment and from the exhaust aftertreatment devices. The hood assembly of the present disclosure finds particular application in assisting large track type tractors in meeting ever more stringent exhaust emission requirements without extensive and expensive redesign alternatives.
