Patent ID: 8082730

Claim:
An internal combustion engine system comprising: an engine, including an engine housing; an exhaust system, including an exhaust manifold coupled with the engine housing; a turbine disposed within the exhaust system; a particulate reduction device disposed in the exhaust system at a location which is fluidly between the turbine and the exhaust manifold; the particulate reduction device including 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 through the particulate reduction device; wherein the engine system further includes a rotary mechanism rotatable via the turbine to generate energy, an energy storage device coupled with the rotary mechanism, and a regeneration device coupled with the particulate reduction device and with the energy storage device; and wherein the engine system has a higher load state at which the particulate reduction device self-regenerates such that particulates passing through the particulate reduction device are oxidized via residence therein, a first lower load state at which the particulate reduction device regenerates via energizing the regeneration device with the energy storage device such that particulates trapped within the particulate reduction device are oxidized via supplemental heat of the regeneration device, and a second lower load state at which the rotary mechanism charges the energy storage device.
