Engine system having particulate reduction device and method |
摘要 |
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. |
