Beschreibung
Zusammenfassung:	A system is provided for removing particulate matter from a diesel particulate filter. The diesel particulate filter includes at least one diesel particulate filter unit to filter particulate matter from diesel engine exhaust gas received from a diesel engine. The system includes a sensor positioned adjacent to at least one diesel particulate filter unit, where the sensor is configured to determine the extent of particulate matter trapped within the diesel particulate filter unit. The system further includes an engine controller coupled to the sensor and the diesel engine, where the sensor is configured to output a first alert signal to the engine controller upon determining that the trapped particulate matter exceeds a predetermined threshold. The engine controller is configured to increase the temperature of the diesel exhaust gas entering the diesel particulate filter upon receiving the first alert signal.
