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.

System and method for reducing particulate matter emission in diesel exhaust gas

A diesel combustion system with a re-entrant piston bowl utilizes momentum interaction with the bowl at multiple locations to cause recirculation of the partially burned fuel and combustion products in a toroidal flow so as to consume soot formed during an earlier portion of the combustion process, while reducing the formation of NOand improving fuel efficiency of the engine.

A locomotive includes an engine (), an intercooler (), and an oil cooler (), each having respective cooling passages formed therein. The locomotive also includes a cooling system () in selective communication with the respective cooling passages for selectively providing a first coolant () and a second coolant () at a higher temperature than the first coolant to the cooling passages. A method of operating the cooling system includes providing, in a first mode, a first coolant flow () to the intercooler and a second coolant flow () to the oil cooler at a first temperature different than the first coolant flow to achieve preferential cooling of the intercooler. The method also includes providing, in a second mode, the first coolant flow to the intercooler and the second coolant flow to the oil cooler at a second temperature different than the first coolant flow to achieve preferential cooling of the oil cooler.
