A panel assembly includes a panel member, a frame member, and at least one first bar member, and at least one second bar member. The at least one first bar member and the at least one second bar member divide the panel member into a plurality of first areas defining a first height and a first width. The panel assembly also includes a plurality of support arrangements for dividing each first area into a plurality of second areas. Each support arrangement includes a first support member defining a first length such that the first width defined by the first area is greater than the first length. Each support arrangement also includes a second support member defining a second length such that the first height defined by the first area is greater than the second length.

Panel assembly and aftertreatment assembly including panel assemblies

A fluid system for a machine includes a tube assembly and a sock filter enveloping the tube assembly. The fluid system also includes a filter protector adjacent to a fastener in the tube assembly and including a first connector fitted with a first tube, a second connector fitted with a second tube, and a wall that arcs between the first connector and the second connector and limits contact between a sock filter enveloping the tube assembly and the fastener.

An inlet filter is disclosed for use with a reductant tank having a fill spout. The inlet filter may have a generally cylindrical base portion with an open top end and an open bottom end and configured for mounting inside the fill spout. The inlet filter may also have a mesh bag with a top connected to the generally cylindrical base portion, a folded bottom, and open side edges. The inlet filter may further have a bag carrier configured to close the open side edges.

Fluid reservoir having inlet filtering

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.

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.

A fluid reservoir includes a reservoir body forming a reservoir volume and a header opening. A header seals the header opening and includes at least a heater disposed within the reservoir volume and a fluid draw conduit. A bag filter is connected to the header such that it completely encloses the heater and the fluid draw conduit such that, when fluid is drawn from the reservoir volume through the sump location, the fluid is filtered by the bag filter.

Filter system and filtration method for fluid reservoirs

A fluid delivery system includes a fluid reservoir having an inlet screen and a main reservoir filter. The fluid reservoir is adapted to enclose a fluid therewithin and includes a reservoir body forming a reservoir volume that is fluidly connected to an inlet conduit, a supply conduit, and a return conduit. The inlet screen is disposed fluidly along the inlet conduit and adapted to filter a fluid provided to fill the reservoir through the inlet conduit. The main reservoir filter is disposed fluidly along the supply conduit and adapted to filter a fluid drawn from the reservoir volume and provided through the supply conduit to a pump.
