  • Publication number: 20190280555
    Abstract: An enclosure for a generator includes an air inlet formed at a first end of the enclosure, and an air inlet opening formed in a sidewall of the enclosure. The air inlet includes an air inlet duct formed in an interior space of the enclosure, and in fluid communication with the air inlet opening. The air inlet duct receives the airflow from the air inlet opening to direct the airflow towards an air outlet of the enclosure. The air outlet includes an air outlet duct formed at a second end of the enclosure which receives the airflow from the air inlet opening. The air outlet duct directs the airflow towards an air outlet opening formed in a top plate of the enclosure which provides an exit for the airflow to escape from the interior space to an ambient environment of the enclosure.

  • Patent number: 9650932
    Abstract: An insulated reductant tank that is arranged so that it has an insulated upper portion and a tapered lower portion, the reductant tank configured to allow frozen reductant to move into the insulated upper portion and reduce the damage that frozen reductant can cause to a reductant tank when the frozen reductant expands. The insulated reductant tank can include at least one header configured to draw reductant from the reductant tank and supply the reductant to an exhaust aftertreatment system, an insulation layer lining an upper portion of the reductant tank, a tapered lower portion, and at least one baffle configured to control a flow of reductant.

  • Publication number: 20160032810
    Abstract: An exhaust gas aftertreatment system includes an exhaust conduit having an inner wall, and a mixer mounted inside the exhaust conduit. The exhaust conduit defines a passage along a length of the exhaust conduit for exhaust gas flow therethrough. The mixer includes first bars coupled to second bars. Each first bar includes deflectors on a straight section, a first end, and a second end. The one or more of the first bars include a curved section at the first end and the second end. Each second bar includes a straight section, a third end, and a fourth end. The one or more of the second bars include a curved section at the third end and the fourth end. The mixer is mounted inside the exhaust conduit by coupling the curved section of the first bar and the second bar to the inner wall of the exhaust conduit.
