    摘要： Various methods and systems are provided for an engine system for a vehicle. In one example, the engine system includes a turbocharger including a turbine, the turbocharger configured to be driven via exhaust gas from an engine during a turbocharger mode and via the exhaust gas from the engine and mechanical output from the engine during a supercharger mode. The engine system further includes a bypass control element to decrease an amount of energy extracted from exhaust flow through the turbine in a regeneration mode of operation and to increase an amount of energy extracted from exhaust flow through the turbine during a non-regeneration mode of operation, and an aftertreatment system disposed downstream of the turbocharger and including a particulate filter.

    摘要： A method is provided including determining a first power level required from a diesel powered system. The first power level corresponds to a first proportion of a maximum power. The method also includes determining an emission output for a mission based on the first power level. The method further includes determining a second power level corresponding to a second proportion of the maximum power, wherein alternate use of the second power level and at least one of the first power level or a third power level results in a lower emission output for the mission, with the overall resulting power being proximate the minimum power required. The method also includes automatically controlling operation of the diesel powered system by using the second power level alternately with at least one of the first power level or the third power level.

    摘要： An aftertreatment system is provided for reducing particulate matter emission and chemical emissions in diesel engine exhaust gas. The system includes a diesel particulate filter including a plurality of diesel particulate filter units configured to engage respective cross-sectional regions of the diesel engine exhaust gas including particulate matter. Each diesel particulate filter unit includes a plurality of channels aligned in a flow direction of the diesel engine exhaust gas. The channels are selectively configured with a distinct cross-sectional area density. Additionally, each diesel particulate filter unit includes a plurality of walls separating adjacent channels of the plurality of channels, where the walls have a respective thickness. A plurality of pores are configured to vacate a distinct ratio of the area of the walls.
