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.

A particulate removal tool and method are provided to remove the particulates such as ash and soot from a particulate filter. The particulate filter can be placed on a filter holder in a housing of the tool where a quick burst of air can be provided to clean the particulate filter. The air then can travel to a container which includes additional filter to filter the air. A vacuum can be used to remove additional particulates from the container.
