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.

摘要： A system is provided for removing particulate matter from a diesel particulate filter. The system includes an engine controller coupled to the diesel engine, and to a locomotive controller. The locomotive controller includes an algorithm to create a trip plan to optimize the performance of the locomotive along a route in accordance with a power setting of the diesel engine at each location along the route. Each sensor is configured to output a first alert signal to the engine controller once the trapped particulate matter exceeds a predetermined threshold. Upon receiving the first alert signal, the engine controller communicates with the locomotive controller to determine a time region or distance region within the trip plan when the power setting exceeds a power threshold. The engine controller increases the temperature of the diesel exhaust gas entering the diesel particulate filter during the time region or distance region.
