20080196389 | Soot filter regeneration software, methods and systems - One embodiment is a method including maintaining a count based upon an engine operating condition, determining a soot level based upon a characteristic of a diesel particulate filter, and requesting deSoot based upon the count meeting or exceeding a threshold, or the soot level meeting or exceeding a threshold, or both. Further embodiments, forms, objects, features, advantages, aspects, and benefits shall become apparent from the following description and drawings. | 08-21-2008 |
20080196392 | Flexible fuel injection for multiple modes of diesel engine exhaust aftertreatment - One embodiment is a system including a controller operable to control fuel injection events. The system is operable in a base mode, and at least one of a deNOx mode, a deSOx mode, and a deSoot mode. The base mode includes a pilot injection pulse, a main injection pulse, a post injection pulse, and a second post injection pulse. The deNOx mode includes a pilot injection pulse, a main injection pulse, and a post injection pulse. The deSOx mode includes a pilot injection pulse, a main injection pulse, a post injection pulse, a second post injection pulse, and a third post injection pulse. The deSoot mode includes a pilot injection pulse, a main injection pulse, a post injection pulse, a second post injection pulse, and a third post injection pulse. Further embodiments, forms, objects, features, advantages, aspects, and benefits shall become apparent from the following description and drawings. | 08-21-2008 |
