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.

Filter service system and method

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.
