SYSTEM AND METHOD FOR REMOVING PARTICULATE MATTER FROM A DIESEL PARTICULATE FILTER

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.
