    摘要: A dosing system for dosing diesel exhaust fluid (DEF) into an inlet of a selective catalytic reduction (SCR) aftertreatment module of a diesel engine is described. The dosing system may comprise a DEF supply line configured to deliver the DEF from a pump to a first injector and a second injector at the inlet. The DEF supply line may include a tri-axis connector configured to split the DEF from the pump into two portions each exiting one of a first outlet port and a second outlet port, a first delivery conduit configured to deliver the DEF exiting the first outlet port to the first injector, and a second delivery conduit configured to deliver the DEF exiting the second outlet port to the second injector. The first injector and the second injector may dose the same quantity of the DEF into the inlet of the aftertreatment module.

    摘要: A header unit for a reductant tank is provided. The header unit includes a reductant draw conduit extending into an interior space of the reductant tank. The reductant draw conduit is configured to draw a reductant from the reductant tank. The reductant draw conduit includes at least one expansion opening provided along a length thereof. The header unit also includes a valve element coupled to the reductant draw conduit. The valve element includes a main body member defining a channel therethrough. The main body member circumferentially surrounds at least a portion of the reductant draw conduit corresponding to the at least one expansion opening. The main body member is made of an elastomeric material configured to accommodate an expansion thereof.

    摘要: 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.
