Abstract: According to an exemplary embodiment of the present disclosure, a system for removing matter from a filtering device of a work machine includes a gas pressurization assembly. An element of the gas pressurization assembly is removably attachable to a first orifice of the filtering device without removing the filtering device from a work machine to which the filtering device is connected. The system also includes a heat source fluidly connected to the gas pressurization assembly.

Abstract: An internal combustion engine system includes an engine having an engine housing. The engine system further includes an exhaust system, and a turbine disposed within the exhaust system. A particulate reduction device is disposed in the exhaust system upstream of the turbine. The particulate reduction device includes an exhaust retarder having a flow property which is based at least in part on a residence requirement for combustion of particulates in exhaust gases passing therethrough. The flow property may be a flow restriction property, and the exhaust retarder may include a flow restricting trapping element configured to trap particulates in the exhaust gases. The flow restricting trapping element defines a combustion efficacy to exhaust mass flow and temperature coefficient for the particulate reduction device which is based at least in part on a combustion initiating residence requirement for particulates passing through the particulate reduction device.

Abstract: An engine exhaust treatment system. The treatment system includes and a reductant injector adapted to deliver a reductant composition into an exhaust stream moving along an exhaust flow path. A selective catalytic reduction device is disposed downstream from the reductant injector. The selective catalytic reduction device is adapted to reduce an amount of NOx in exhaust gases produced by an engine by reaction of the NOx with ammonia. A basic and/or amphoteric oxide contact surface is disposed along the exhaust flow path.

Abstract: A particulate filter and a method for reducing pollutants are provided. The particulate filter comprises at least one first piece, said first piece comprising non-linear channels, and at least one second piece adjacent to the at least one first piece. The particulate filter is configured such that either the at least one first piece or the at least one second piece comprise either sintered metal fibers or porous metallic foam. The method comprises the steps of providing a particulate filter, said filter comprising, at least one first piece, said first piece comprising non-linear channels and at least one second piece adjacent to the at least one first piece, catalyzing the particulate filter with a catalyst, passing exhaust stream through the filter, filtering at least some soot from the exhaust stream, and chemically converting at least some NOx from the exhaust stream with the catalyst.

Abstract: An exhaust emission control regeneration system regenerates a particulate filter by combusting trapped particulate and producing a combustion product from such combustion, and uses the combustion product to assist regeneration of a downstream catalyst, such as CO assisting regeneration of a downstream NOX adsorber, located in sufficiently close proximity to a diesel particulate filter.
